There’s Power in These Pushrods! Admittedly, the weakest link in a Harley® performance engine is the valve train stiffness, or rather the lack of it. These high performance adjustable pushrods add much needed stiffness to the valve train.
Our Pro-Taper pushrods are also available for the professional engine builder who wants the stiffest adjustable pushrods available. The weakest link in an adjustable pushrod is the adjuster itself; keeping the pushrod adjuster as short possible helps maintain the highest resistance to deflection. For this reason we offer the Pro-Taper pushrods, sold each, in the fully collapsed lengths listed below so you can order exactly the lengths you need to keep the adjuster extension at a minimum, for maximum rigidity. Pushrods are chrome moly, .095” wall, 7/16” diameter at the bottom tapering to 3/8” at the top with a full radius rocker ball tip. Adjuster thread is 5/16” x 1.250” length, 32 TPI.
Note - Pushrods are sold each. Depending on your tappets and pushrod tube length the length of the lower adjuster may not be ideal for ease of adjustment.
Need custom length pushrods? These solid pushrods are made from heat treated .065” wall seamless 3/8” chrome moly tubing and are supplied with full radius “Mae West” tips (drilled for oil flow) for use with the highest lift cams. They are supplied extra-long with one end unfinished, to be custom fitted by the engine builder. Cut, drill end .250”, ream 17/64”, press in tip. Use with adjustable lifters or customize length for hydraulic lifter pre-load. Sold each.
S&S “Quickee” Chrome Moly Adjustable Push RodsFits: Harley Davidson Twin Cam- M8 Engines
These Quickee pushrods can be both installed and removed easily. The S&S® design permits a simple, trouble free installation that does not require removal of the gas tank, rocker assemblies, or even the rocker box cover! This especially pertains to M8 models that have a coolant line that covers the rocker boxes. Use of these pushrods allow you to leave the coolant lines undisturbed on M8 models.
OEM pushrods may be cut to permit removal without rocker disassembly. The threaded adjuster screws into the pushrod until the threads disengage and the adjuster simply slides into the pushrod, making installation or removal a snap. Once the pushrod is installed and adjusted, the locknut prevents the adjuster from moving.
Adjustable to accommodate all tappets, cam base circle diameters and cylinder head-engine heights. 1984-'99 style pushrod covers are required for access to the Quickee Adjustable Pushrod adjusters in 2007-'12 Twin Cam.
#713-901 Building specialty engines can require making special length pushrods. This inexpensive tool makes measuring the pushrod lengths a snap. Simply set your lifter adjuster to the desired length (we like to keep them as short as possible for increased strength), install the checking pushrod, telescope it to the proper length, measure the gap and remove. Re-set gap and measure then machine your new pushrods to the proper exact length. For Twin Cam®, EV and Shovel engines.
Five speed Sportster® and Buell® engines require that you remove the cylinder heads and take off the one-piece pushrod covers to get to the pushrods, greatly complicating pushrod adjustments for tuning or maintenance when adjustable pushrods have been installed. These telescoping pushrod cover kits permit access to the pushrods without having to lift the heads. Pre-’04 XL and Buell XB kits include twin billet aluminum bases with special seals for the front and rear cylinders that replace the factory pushrod tube lower retainers. A full telescoping pushrod cover kit is included. The twin bases can be purchased separately if desired.
