Manton Duramax Pushrod Length Checking Tool Kit

The Manton Duramax Pushrod Length Checking Tool Kit is designed to accurately measure pushrod length for custom engine builds, cylinder head work, camshaft upgrades, and valvetrain modifications. Proper pushrod length is critical to maintaining correct rocker arm geometry, valve train stability, and long-term engine reliability.

Changes to cylinder heads, camshafts, deck height, lifters, rocker arms, or other valvetrain components can affect required pushrod length. This kit allows builders and machine shops to accurately determine the correct pushrod length before ordering custom pushrods or completing engine assembly.

Why Check Pushrod Length?

Engine modifications such as cylinder head machining, block decking, camshaft changes, lifter variations, and aftermarket valvetrain components can all affect required pushrod length. Verifying pushrod length helps ensure proper oiling, valve motion, and rocker arm geometry while reducing the risk of premature component wear.
