COMP Cams Lifters BBC Retro-Fit Hydraulic Roller XD

When you're building a high-performance Chevrolet Big Block engine, the right lifters make a big difference. This set from COMP Cams includes their XD Short Travel Hydraulic Roller Lifters, designed to give you the best of both worlds: the quick recovery of a light lifter pre-load and the increased stiffness from reduced oil volume under the plunger. This combination helps create the most stable and highest-revving hydraulic lifter available for your build.

What sets these XD lifters apart is the inclusion of a heavy-duty tool steel pushrod seat. This upgrade adds significant strength and durability, making them a solid option for Xtreme Duty applications like turbo drag cars or offshore powerboats where the valve train sees a lot of stress. The short travel design itself is key, allowing for precise control over pre-load and oil flow, which translates directly to a more consistent and responsive valve train, especially at higher RPMs. These are designed as a retro-fit for a variety of Chevrolet Big Block engines, meaning they can bring the benefits of modern hydraulic roller technology to older, classic powerplants.

This set includes all 16 lifters needed for a typical V8 engine. COMP Cams is well-known for their engine building components, and this lifter set is a prime example of their focus on performance and durability. If you're aiming for maximum RPM and a stable valve train in your Big Block build, these lifters are a strong consideration.
