Are these lifters compatible with hydraulic roller camshafts?

No, these are solid roller lifters and are designed to be used with solid roller camshafts. Using them with a hydraulic roller camshaft is not recommended and can lead to improper valve train function.

What is the purpose of the cutaway body and oil band?

The cutaway body design helps reduce weight and can improve oil flow around the lifter. The oil band is specifically designed to help manage and distribute oil to the roller and the lifter bore, which is crucial for lubrication and cooling in high-stress applications.

Do these lifters require periodic adjustment?

Yes, as solid lifters, these COMP Cams Endure-X lifters will require periodic valve train adjustment to maintain proper lash. This is a normal part of maintenance for solid lifter camshafts.

Product Details

If you're building a high-performance GM LS Gen III engine, these COMP Cams Endure-X Solid Roller Lifters are a solid choice for serious power. Designed for applications like the LS1, LS2, and LS6, these lifters are built to handle the demands of aggressive camshaft profiles and high RPMs. They feature a cutaway body with an oil band, which helps manage oil flow and lubrication, crucial for keeping solid roller components cool and functioning correctly under stress.

These are not your average lifters; they are specifically engineered for racing and performance builds where durability and precise valve train operation are paramount. The .842-inch diameter and centered design ensure they fit correctly within the compatible GM LS blocks. Remember, these are intended for off-road or racing use only and are not street-legal. COMP Cams is well-known for producing reliable valve train components, and this set of 16 lifters is built to endure the rigors of competition.

When installing solid roller lifters, it's important to ensure your entire valve train is set up correctly. This includes checking pushrod length and rocker arm geometry to maintain proper contact with the lifter's roller. Because these are solid lifters, they require periodic adjustment as part of regular engine maintenance, unlike hydraulic lifters. Make sure you consult the manufacturer's installation guidelines for best practices.
