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

This compact, workshop‑ready tool helps engine builders, racers, and DIY mechanics set accurate pushrod lengths without relying on expensive calipers. Made from a durable steel alloy with a black‑oxide finish, the checker gives repeatable readings and resists corrosion and wear during repeated use. Its ball‑ball ends simulate rocker and lifter seating for a realistic measurement, helping you dial in rocker arm geometry quicker and with less guesswork.

How does the adjustable range simplify pushrod selection?

The 6.800"–7.800" range covers the most common pushrod lengths needed for a wide variety of small‑ and big‑block V8 builds, overhead‑valve swaps, and performance heads. Because the tool advances in 0.050" steps, you can quickly step through candidate lengths to find the ideal fit rather than measuring and regrinding multiple parts.

• Range: 6.800" to 7.800" in 0.050" increments for broad compatibility
• Quickly test multiple lengths without additional tools
• Ball‑ball ends replicate real contact points for accurate setup

What materials and finish ensure lasting accuracy?

Constructed from a steel alloy, the checker maintains rigidity under repeated use and resists bending that could skew readings. A black‑oxide finish protects the surface from light corrosion and reduces glare, making marks and graduations easier to read in real workshop lighting.

• Steel alloy body for strength and dimensional stability
• Black‑oxide coating for abrasion and rust resistance
• Machined graduations remain legible after extended service

How do I use the ball‑ball ends to get an accurate measurement?

The ball‑ball end configuration mimics the rocker arm-to‑lifter contact points, providing a realistic span for determining ideal pushrod length. Set the checker between the lifter and rocker, adjust to take up valve-train lash, then note the selected length—this gives a true starting point for final pushrod selection or trimming.

• Seat each ball end against the lifter and rocker contact points
• Adjust until the clearance matches target valve‑train geometry
• Record the measured length and select the nearest pushrod size

Why choose a dedicated pushrod length checker over calipers?

A dedicated length checker speeds setup by eliminating conversion steps and interpretation errors common with calipers. It’s purpose‑built to reproduce valve‑train contact conditions and gives instant, repeatable measurements, saving time during mock‑up and final assembly.

• Designed specifically for pushrod measurement—no conversions needed
• Faster, more realistic readings than flat tool measurements
• Reduces the chance of selecting a pushrod that requires unnecessary rework

Who is this for? Engine builders, performance technicians, weekend hot‑rod enthusiasts, and professional race teams who need a fast, reliable way to determine pushrod length will benefit from the COMP Cams Hi‑Tech Pushrod Length Checker. It’s particularly useful during cylinder head swaps, valvetrain rebuilds, and custom rocker arm installations where accurate geometry is crucial. Lightweight and rugged, it fits into a toolbox or trackside kit so you can verify or adjust lengths wherever you’re working.
