What is the primary benefit of using solid roller lifters over hydraulic lifters?

Solid roller lifters can handle higher engine speeds and valve spring pressures compared to hydraulic lifters. This makes them ideal for performance builds where increased RPM and more aggressive camshaft profiles are used, ensuring more consistent valve train operation.

Are any special tools or modifications needed for installation?

Installation of solid roller lifters typically requires specific knowledge of valve train geometry and may involve adjustments to pushrod length. Always refer to the COMP Cams installation instructions for detailed guidance and recommended procedures.

What is the advantage of the staked axle design?

The staked axle design permanently secures the axle, eliminating the need for retaining clips. This provides more robust axle retention, which helps prevent the lifter ears from spreading under high stress, contributing to overall lifter durability.

Product Details

If you're rebuilding the top end of a GM LS engine, especially for performance applications, a solid roller lifter set like these from COMP Cams is a critical component. These lifters are designed to handle the higher valve spring pressures and faster camshaft speeds common in performance builds, ensuring reliable operation and consistent valve train geometry. They are a step up from standard hydraulic lifters and offer a value alternative to more extreme race-oriented options.

COMP Cams built these Sportsman lifters with durability and performance in mind. They're constructed from 8620 steel, which is known for its strength and wear resistance, making them well-suited for demanding use. The design features two pressurized oil feeds to the axle and an edge orifice feed to the wheel, providing a more consistent oil supply than many other lifters. They also have a shallower oil band for increased strength and internal machining to reduce weight. The skirted wheel design adds rigidity to the lifter ears and provides more contact with the lifter bore for better stability. Staked axles replace clips for more robust retention, preventing the ears from spreading under stress. The tall body design allows them to fit in both standard and .300" taller lifter bores, offering flexibility and reducing wear on the lifter bore.

This set includes 16 lifters, enough for a complete V8 engine, and is designed to fit a wide range of GM LS engines, including those found in vehicles like the Chevrolet Camaro, Cadillac CTS, and GMC Sierra. They feature a centered pushrod seat and a captured link bar design with a tapered and slotted tower for reduced weight and a cleaner look. If you're looking for a well-built, reliable lifter set for your LS engine build, these COMP Cams Sportsman lifters are a solid option.
