Low Tension Checking Springs (2pk)

Low Tension Checking Springs by COMP CAMS are precision-engineered valve train components designed for camshaft degreeing and engine tuning applications. These springs serve as essential diagnostic tools for engine builders, performance mechanics, and motorsports professionals who need to verify camshaft timing and valve overlap during engine assembly and calibration. A two-pack configuration ensures you have backup springs for multiple engine builds or comparison testing without interruption to your workflow.

Manufactured from high-grade steel in natural finish, these checking springs measure 3.0 inches in length with a 0.725-inch inner diameter and 0.850-inch outer diameter—specifications that align with standard small-block and mid-size engine platforms. The low-tension design minimizes valve train resistance during the degreeing process, allowing for accurate observation of valve opening and closing points without the dampening effect of full-load performance springs. This reduced spring force is critical for detecting subtle timing variations that could affect engine efficiency, emissions compliance, or power delivery once performance springs are installed.

Engine builders and tuners rely on low tension checking springs to isolate camshaft variables before committing to final assembly with race or street springs. The pair format is ideal for V8 engines requiring dual setups or for shops maintaining multiple test benches. Installation is straightforward for anyone with basic valve spring removal experience, and the lightweight construction (0.05 lbs per pair) makes handling and positioning simple. These springs are compatible with any engine platform using standard 0.725-inch bore valve springs and represent an economical, repeatable solution for professional-grade engine diagnostics.
