What is the main difference between a solid roller lifter and a hydraulic roller lifter?

Solid roller lifters have a fixed height and require manual adjustment of valve lash. Hydraulic roller lifters use oil pressure to maintain zero lash automatically. Solid rollers are generally preferred for high-RPM racing applications due to their stability.

How many lifters do I need to buy for my V8 LS engine?

Since these are sold individually, you will need to purchase eight lifters for a standard V8 LS engine. It's always a good idea to confirm the cylinder count of your specific engine configuration.

What does 'not for street use' mean for these lifters?

This designation means the lifters are designed for the extreme demands of racing and may not provide the quiet operation or longevity required for daily driving. They are optimized for performance and durability under race conditions.

Product Details

These COMP Cams Endure-X solid roller lifters feature a .842-inch diameter and a centered oil band, designed specifically for GM LS Gen III engines like the LS1, LS2, and LS6. The cutaway body design helps reduce weight and allows for better oil flow, which is crucial for high-performance applications. While they are well-built for demanding use, it's important to note that these are not intended for street applications and are best suited for dedicated racing or performance builds where maximum valve train stability is required.

The solid roller design means these lifters have a fixed height and require proper setup with your camshaft and valve springs to ensure correct geometry and valve lash. Because they are a single lifter, you'll need to purchase the correct quantity to match the number of cylinders in your engine, typically eight for most V8 LS applications. If you're rebuilding the top end of your LS engine for competition, these lifters offer a solid option for consistent performance under stress.
