COMP Cams 7903-1 Magnum Pushrod Length Checker Tool - 9.700 to 11.000

The COMP Cams 7903-1 Magnum Pushrod Length Checker is an essential tool for accurately determining the correct pushrod length for your engine build. This precision measurement tool adjusts from 9.700 inches to 11.000 inches, covering the most common pushrod length requirements for small block and big block V8 engines.

Key Features:

• Adjustable length range from 9.700" to 11.000" for versatile application
• Hardened steel construction with aluminum body for durability and accuracy
• Ball and cup ends simulate actual pushrod operation
• Lock nut design maintains selected length during measurement
• Eliminates guesswork when selecting custom pushrod lengths
• Essential for confirming proper geometry with aftermarket rocker arms, cylinder heads, or deck height changes

Proper pushrod length is critical for optimal valvetrain geometry, ensuring correct rocker arm sweep pattern and maximizing valve lift. This checker allows you to accurately measure the required length with the engine assembled, ensuring you order the correct pushrods the first time. Simply install the checker in place of a pushrod, adjust to achieve proper geometry, lock the setting, remove and measure for your exact pushrod length specification.
