Pushrod Length Checker - 6.800" - 7.800"

Pushrod Length Checking Tool

For measuring pushrod length between 6.800"-7.800"

Pushrod length checking tools are precision crafted from steel alloy and black oxide for years of accurate measurements. Their unique designs are easy to read and eliminate the need for expensive calipers. Each complete revolution is equal to .050 inch.

Having the correct length pushrods in your engine is a critical factor in proper rocker arm geometry and these are the best tools to measure pushrod length.

Instructions:

Make sure the lifter is on the base of the cam lobe

Torque the rocker arm to spec (22lbs with stock rockers)

Rotate tool until you are at 0 preload.

Then add the necessary preload to the measurement shown on the tool. We recommend a .070"-.100" preload on a LS7 style Lifter.

As an example: If using LS7 lifters and the pushrod tool shows 7.330 at zero preload then you will want a 7.400 pushrod (7.330+.070=7.400)
