New Red Shift Cams® Chain Tensioners system for the Milwaukee Eight® Engines.

The patented Red Shift dual piston, dual feed tensioners system and sprockets will help maintain the proper tension on the cam chain for more accurate valve timing. This system comes with a stronger, tighter fitting crank drive gear and cam gear to center the chain up accurately on the tensioner. This revolutionary design using multiple hydraulic bodies is simple and effective, improving cam chain tension stability, hydraulic performance, and valve train control for a quieter, better running engine. A staple in Twin Cam builds is now available for Milwaukee Eight® engines as well!

This system comes complete with offset crank and cam drive gears so you can properly align the chain to the tensioner shoe, while providing a tighter more stable fit in the crank pinion shaft. This system is a great upgrade for any rebuild, adding cams or when constructing a new high-performance engine.

What you can expect:
• Dual Pistons Eliminates Chain Instability via Tensioner Piston “Rocking”
• Dual Feed Oil and Larger Reservoirs for Improved Hydraulic Performance
• Durable Long Wear Tensioner Shoe
• Facilitates Accurate Cam Timing Events for Both Cylinders
• Better Compatibility to O.E. or Aftermarket Cranks than Gear Drive Cams

    Waited for this product to come back into stock and ordered it. I had it installed while my RGS 128 Sleeper was being serviced at T-Town HD. It really sures up the cam area while properly securing/reducing any potential of timing loss on the cam. This product is well worth the wait.

    2024 CVOST noisy valve train; replaced lifters, was not the answer. Shim rockers again, not the answer. Replaced cam chain tensioner, part #413-801 all good, very quiet motor. I could not be happier.

    2024 CVOST – Very noisy valve train. I replaced lifters and shimmed rockers with little to no improvement. Spoke with Pete from Zippers and he recommended #413-801 cam chain tensioner kit. Noise is gone. I am very happy. I highly recommend this part if you are having valve train noise and can’t find the culprit.
