Comp Cams Hi‑Tech Pushrod Length Checker 6.800–7.800 Adjustable Steel Gauge, Ball‑Ball Ends, 0.050" Steps

The Comp Cams Hi‑Tech Pushrod Length Checker is an adjustable steel‑alloy gauge that measures pushrod lengths from 6.800" to 7.800" in 0.050" increments with ball‑ball ends for quick, repeatable valve train setup.

When tuning valve train geometry or confirming pushrod lengths, accuracy and repeatability matter. This tool from Comp Cams is engineered to replace guesswork and expensive measuring tools by delivering a rugged, calibrated gauge you can trust in the garage or on the dyno. Its black oxide finish helps resist corrosion while the ball ends mimic real rocker and lifter contact points for realistic measurements.

How precise is the length adjustment and how easy is it to read?

The pushrod checker adjusts in clearly marked 0.050" steps across a full inch range, giving you predictable, repeatable settings without relying on calipers. The scale and stop mechanism are designed for visible, tactile feedback so you can dial in a length and lock it for installation or comparison.

• Adjustable from 6.800" to 7.800" in 0.050" increments
• Positive detents that confirm each quarter‑inch click
• Clear markings eliminate second‑guessing measurements
• Lockable setting preserves the chosen length while handling

Will this tool simulate real rocker and lifter contact?

Yes — the Comp Cams checker uses ball‑to‑ball ends to approximate the curved contact surfaces of rockers and lifters, providing a realistic feel when evaluating pushrod length. That practical contact helps you establish correct geometry before committing to final parts or shimming.

• Ball‑ball ends reproduce contact points for more accurate geometry checks
• Reduces errors when switching from prototype to final pushrods
• Helps verify rocker arm pattern and tip location without engine overhaul

What materials and finish protect the tool for shop use?

Built from a hardened steel alloy and finished with a black oxide coating, the checker is resistant to routine shop wear and surface corrosion. The robust construction maintains calibration over time, even with frequent use under greasy, high‑temperature conditions.

• Steel alloy core for dimensional stability and toughness
• Black oxide finish adds corrosion resistance and low glare
• Durable threads and locking mechanism withstand repeated adjustments

How does this replace expensive calipers or other measuring tools?

By offering a direct, mechanical length setting with realistic contact points, the tool simplifies the process of finding correct pushrod length without the need for precision calipers or micrometers. It saves time during mock‑up and teardown by giving a trusted, hands‑on reference that fits in a toolbox.

• Direct length setting avoids multiple measurement conversions
• Faster mock‑up and verification compared with digital tools
• Compact and portable — ideal for trackside or shop use

Who is this for? The Comp Cams Hi‑Tech Pushrod Length Checker is suited to engine builders, performance enthusiasts, and professional technicians who need a quick, repeatable way to determine pushrod length during assembly or setup. If you work with aftermarket rocker arms, adjustable pushrods, or routinely tune valve train geometry, this tool streamlines the process and reduces reliance on trial‑and‑error fitting.
