Pushrod Length Checker 5.800-6.800

The COMP Cams Pushrod Length Checker 5.800-6.800 in is a precision measurement tool designed for engine builders and performance mechanics who need to verify correct pushrod length before final engine assembly. This steel instrument with black oxide finish eliminates the guesswork that can lead to valve train damage, making it an essential quality-control device for small-block and big-block engine builds.

Measuring 3.25 by 0.85 by 6.6 inches and weighing just 0.12 lbs, this checker accommodates pushrods ranging from 5.800 to 6.800 inches in length. The black oxide coating resists corrosion during repeated use in the shop, while the precise internal gauges allow for quick verification of pushrod fit without removing components from the engine block. Proper pushrod length is critical—undersized pushrods cause valve train geometry errors and potential valve float, while oversized pushrods can bind rocker arms or restrict valve opening.

This tool addresses a common pain point for engine builders working with aftermarket cylinder heads, stroker blocks, or modified rocker arm ratios where OEM pushrod lengths no longer apply. Whether building a street performance engine or preparing a race-ready package, confirming correct pushrod length before startup prevents costly bearing wear, valve seat recession, and potential catastrophic engine failure. COMP Cams' pushrod length checkers are industry standard for validation across Chevrolet, Ford, Mopar, and other domestic V8 platforms where this measurement range applies.
