Race XD Solid Roller Lifters are the strongest, most durable and versatile lifters available from the leader in valve train technology, COMP Cams. Designed to be the most versatile solid roller lifters available, COMP Cams Race XD lifters feature a lightweight modular design with five interchangeable pushrod seats. Available in medium or large offsets with left or right placement, the COMP Cams Race XD series lifters are configurable to clear even the most extreme intake angles. REM finished bodies create an extra smooth surface for reduced lifter body and lifter bore wear. An available DLC-coated lifter body coating further minimizes friction for the ultimate in durability. For excellent strength in extreme operating conditions, COMP Cams incorporates a proprietary bronze alloy roller bushing, while a captured link bar joins individual lifters together. In an effort to eliminate the culprit for most roller lifter failures, axle and wheel oil starvation, COMP Cams developed a new oiling system that ensures consistent roller wheel and axle lubrication. COMP Cams Race XD Solid Roller Lifter sets are available in 0.842” and 0.904” diameter bodies for both Chevrolet Small Block and Big Block engines. 0.080” and 0.160” offset seats are available for 0.842” diameter lifters while 0.090” and 0.180” offset seats fit the 0.904” diameter lifters. All pushrod seats are designed to accommodate both 5/16”and 3/8” ball pushrods.
Race XD lifters for .842″ bore Chevrolet Small Blocks are the strongest and most durable bronze bushed solid roller lifter available, featuring a REM finished surface that reduces wear with a new oiling design to eliminate oil starvation.

Reduced Travel OE-Style Hydraulic Roller Lifters. When dealing with full travel lifters, certain engines respond better to a light pre-load because it recovers more quickly from any bad harmonics in the valve train. Others work better with a heavy pre-load because oil volume is reduced under the plunger, which increases stiffness. COMP Cams Reduced Travel Hydraulic Roller Lifters allow you to have the advantages of both light pre-load and reduced oil volume, producing the most stable and highest revving hydraulic lifter available. Applications: Ford Small Block: Use in Ford OE 302/351W blocks equipped with hydraulic Roller lifters/Roller lifter provisions. Use COMP Cams specially designed Ford Hydraulic Roller Retro-Fit Kit for 289-302, 351W, 351C, 351M, 400M. Use in Aftermarket Blocks with Roller lifter provisions or use Ford Hydraulic Roller Retro-Fit Kit. Specifications: Includes (16), .875″ Diameter, 128g Weight, 2.60″ Seat Height.

Steel Valve Locks – 511-16 Valve Seals – 4705-16 Spring Seats This Beehiveâ„¢ Valve Spring Kit for LS engines is designed for hydraulic Roller cams and includes carefully matched Beehiveâ„¢ Springs, retainers, locks, Seals and spring seats. With a .600″ maximum lift, these Beehiveâ„¢ Valve Springs deliver increased valve train stability and a much lighter valve train. This is achieved with less spring pressure for better valve control and reduced weight of both the spring and retainer. The unique Beehiveâ„¢ shape handles valve train stress more efficiently to eliminate damaging harmonics and increases high RPM horsepower and durability. The oval/multi-arc wire shape places the maximum area of the wire at the point of highest stress to handle valve train stress more efficiently and allow better heat dissipation for longer life. Also Available with Tool Steel Retainers or Titanium Retainers.
Including properly matched quality beehive valve springs, 7 degree locks, viton seals, hardened seats and lightweight tool steel retainers, this spring kit is ready to bolt onto LS heads with aggressive cams with up to .600″ valve lift.
See 26918CS-KIT or 26918TS-KIT for Beehive spring kits that support up to .625″ valve lift. -
