Zipper's Performance Terms and Conditions

The installation of certain performance parts may not be legal for use or installation on pollution controlled motor vehicles operated on public highways and may be restricted to closed-course competition use only in the State of California or other States where similar emission control laws for pollution controlled motor vehicles may apply.  The user shall determine suitability and assumes responsibility for installation and use of the product for his or her use.  Installation and use of such products on a pollution-controlled vehicle constitutes tampering under the U.S. EPA guidelines and can lead to substantial fines and penalties to the installer and user.  Review your application and check your local laws before ordering or installing.



Orders that are in-stock and placed before 3PM EST (US) during the business week will ship the same business day. Orders placed after 3PM EST (US) will ship the next business day.



We accept VISA, MASTERCARD, DISCOVER and AMERICAN EXPRESS credit cards.  We security check all credit card orders.  Some credit card orders may require special procedures.  We reserve the right to refuse payment by credit card on purchases.  Payment may also be made by bank wire; contact us for details.  Components made to order require a non-refundable deposit.  Parts modified or altered at your request must be paid for before any modifications are performed and are not returnable.


All orders placed on will ship via UPS unless other arrangements are made in advance. View the UPS Shipping map below to see what your estimated delivery time is.

Orders over $50 inside the continental US, ship free via UPS Ground. If you wish to receive your order faster, service may be upgraded to UPS Next Day and Second Day service at additional cost.


Customers are responsible for all shipping costs, including any international boarder Tariffs/Taxes/VAT or duty that may occur.

If you would prefer we ship your package via a different service, please call a Zipper’s Sales Representative or include this information in the comments/additional information in Bike Info in your order. You are still responsible for the full shipping payment and any/all Tariffs/Taxes/VAT that may occur, regardless of the freight carrier chosen.


Refused orders will result in a 20% restocking fee plus all freight costs, which must be paid before any future orders will be shipped.  You are ultimately responsible for this cost, regardless of the reason.


Shipments that arrive damaged due to rough handling must be noted with the freight carrier immediately upon arrival. Obviously damaged shipments should be refused, with the reason for refusal clearly noted as damaged on arrival. If an order is unpacked and found to be damaged during shipment, contact the freight carrier immediately and save the carton and its packing contents, as you will need these for your claim. We will assist you with this process.


Prices are subject to change without notice.  We will do our best to hold prices, but with fuel and raw material costs rapidly escalating, many of our vendors are regularly increasing prices.  We will notify you in advance in the case of a price increase before shipping. 


Every effort is made to supply you with the correct parts.  If you suspect you have received an incorrect part STOP!  DO NOT ATTEMPT TO CONTINUE INSTALLATION OR MODIFY THE COMPONENT AS MODIFIED COMPONENTS ARE NOT RETURNABLE! Contact us immediately and we will make every effort to work with you to resolve any problem you may have.

Contact Zipper’s Performance Products immediately for a Return Goods Request Form.  Fill out this form and fax it to 410.579.2835, or email it to your contact person at Zipper’s Performance.  You will be contacted with a Return Goods Authorization (RGA) number and form to send back with the item.

2. Double-box items whenever possible to preserve the original manufacturer’s packaging.  Pack the part carefully – no rattles or shakes!  Parts damaged due to improper packaging will not be credited.  Prepay the return shipping and insure the part for the full amount.

3. Write the RGA number on the outside of the shipping box and include the RGA form and a copy of the original invoice.

Return all original packaging and instructions with the product.  Do not write anything on the part or deface the packaging.  In order for us to credit you, the returned part must be in resalablecondition.  No credit will be issued on parts that have been installed, used, altered, modified or otherwise changed from their original state.  If you suspect that you have an incorrect part, STOP installation and call us.  We will make every effort to work with you to resolve any problem you may have. 

Please be sure of your purchase.  A re-stocking fee of 20% may apply on items returned for credit or refund, less any freight paid by Zipper’s on the original sale and delivery of freight-paid items.

Zipper’s reserves the right to make changes in design, materials and specifications on products and kits without incurring liability or obligation with respect to similar products previously manufactured or sold.  Our R&D program never stops; improvements may be made at any time. 


Zipper’s Cycle, Inc has always been a leader in the manufacture and sale of the highest quality performance parts for Harley-Davidson® based motorcycles. We continually strive to provide services and products in support of racing and high performance, which reflect our reputation and ongoing efforts at improving the sport of motorcycling.

Zipper’s Cycle, Inc. warrants all parts and accessories produced for and by Zipper’s Performance to be free from defects in design and workmanship.  Should the parts be found to be, or become, defective during any stated warranty period, Zipper’s will, at its option upon physical inspection, repair or replace any, or all, defective parts.  Zipper’s will maintain no obligation under the terms of this warranty in the event the parts become defective as a result of improper assembly, installation, break-in, maintenance or use, or any other misuse or mistreatment of the parts including, without limitation, operation of the parts with fuels, oils or lubricants not conforming to specifications published by Zipper’s or continued operation of the parts after a defect or malfunction occurs, is identified or suspected.

Zipper’s will have no obligation under this warranty for parts defective due to alteration including, but not limited to, chroming, polishing, powder coating, painting, removing and modifying components, shot peening, bead blasting, modification, repair or unauthorized service, even when such services or modifications may be performed by Zipper’s at the request of the end user.

All items not manufactured by Zipper’s Cycle, Inc. are warranted to be free from defects under the terms outlined by the specific manufacturer.  Any parts determined to be defective will be repaired or replaced, at the option of the manufacturer, in a prompt and just manner.

Parts identified or intended as racing components carry no warranty, regardless of installation.

There is absolutely no warranty on the following:

     •  Any parts used in a racing application

     •  Any part that has been physically altered, improperly installed or maintained

     •  Any product used in improper applications, abused or not used in conjunction with proper
          related parts

All items sold for installation by the end user, are considered by law to be customer assembled items and carry no liability to the distributor or maker. 

This warranty does not cover any consequential, incidental, or special damages arising out of the use of, or inability to use, parts, components or vehicle to which the parts or components are installed.  Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above exclusion may not apply to you.


Motorcycles can be dangerous.  The products on this website are intended primarily for racing or high performance use by experienced and skilled riders, which imply that these products will be pushed to severe and unusual limits.  Zipper’s has no control over the installation and usage of these items and in no way can Zipper’s Cycle, Inc. assume any liability or responsibility for damage or injury of any type resulting from their use. 

Zipper’s Cycle, Inc. shall not be liable for any indirect or consequential damages whatsoever.

Prices listed are for Labor Only and assume components to be modified are in working, serviceable condition.  Previously modified components may require additional labor at additional cost, or in some cases may not qualify for a Zipper’s-engineered service or kit.  If there is any question concerning your parts and this policy please call before shipping your parts.  Prices listed do not include return shipping charges.

To protect the integrity of the work we perform and the price structure of our kits, we cannot use parts that we do not, or did not, supply in any machine shop job we perform.  Unless you have Zipper’s products or parts that were previously purchased from Zipper’s, do not send parts with your job to Zipper’s.

Most components require some important cleaning and/or preparation steps before work can be performed.  Because improper cleaning methods can actually do more harm than good, we suggest you allow us to properly prepare your parts for modification.  Extreme care is taken during our preparation process to preserve component finishes.  Reasonable additional charges do apply for these services.  Engine and transmission components should be washed free of oil and wrapped in heavy newspaper before being put in protective cartons.  A standard charge is billed to each work order to cover shop costs for chemical disposal and other materials used during the processing of a job. 


Sometimes we receive boxes from our customers that contain parts and major components without any note of instruction on what is asked of us, sometimes without even a return address or a phone number!  Unfortunately, we have to just sit on the parts until somebody starts wondering why it’s taking so long for us to get back with them.  So, before you ship something to us for Machine Shop Services, please read the following instructions.

1. Download the “Zipper’s Job Order Sheet” from our site, or request a PDF from us.  Be sure to fill it out entirely, or enclose a note with the following:

1. Year, make, model, engine size, mileage and current modifications, if any.  It gives us somewhere to start if we have questions.

2. Explain the nature of the work you want performed.

3. Include a cell phone number, daytime and evening phone numbers with fax or e-mail if available.

 If we have questions or need more information, or just want to let you know we’re ready to ship your parts back, these numbers come in really handy.

Package parts carefully.  Items such as heads and cylinders should be first washed clean of oil and individually wrapped in heavy newspaper (a whole section per part works well), then placed in individual boxes or at the very least separated by strips of heavy cardboard and more newspaper padding. Remember your box is going to be thrown around during shipping a lot and could be damaged beyond use if not packaged properly.  Heavy cardboard boxes and cardboard barriers between the parts to protect them are essential (UPS requires at least 2” of padding around packaged components).  Neither the Freight Company nor Zipper’s Performance can take responsibility for poorly packaged parts.  Don’t use bubble wrap on top end parts!  A top end wrapped in bubble wrap will get to us sounding like a big, heavy baby rattle, with all the bubbles popped long before the boxes reach us.  At any rate, always insure your parts for replacement value, but remember, even if your parts are insured, you may not be reimbursed for damages if they are not properly packaged.

Allow for shipping and receiving time.  We receive calls checking the progress of jobs we have not even received yet.  Ask your shipper how long it will take to get your parts to Maryland.  We strive for fast service and quick turn-around, however, in season our workload, like everyone else’s, gets heavy.  Call for current shop time; please be aware that this can change with our daily influx of work.  If you’re in a jam and just can’t wait, consider an outright purchase or exchange (available on many services we offer).  We want to make sure you get quality work on your job, in a reasonable time, so please plan ahead.  Call checking progress may take up to 24 hours to return.  We’ll do our best to give you great service.
