COMP Cams Evolution Series Hydraulic Roller Lifters
COMP Cams Evolution Series hydraulic roller lifters with Hydraulic Cartridge Technology (HCT) are revolutionary patented tappets. A combination of a self-contained hydraulic cartridge within a thick-wall lifter body and accompanying reduced oil volume that is less effected by oil aeration delivers the most consistent bleed rates between each lifter on the market. The smaller volume within the hydraulic cartridge creates one of the most responsive and quietest lifters on the market today. Startup noise is greatly reduced, and a precision-controlled bleed down rate ensures excellent performance at high RPM. The cartridge design also allows for an incredibly stiff lifter body, greatly reducing body distortion and further ensuring consistent hydraulic performance. The patented HCT tappets are a completely new design that was developed specifically by COMP Cams to meet the demanding performance and durability required for modern street and performance street engines. The HCT and proprietary manufacturing processes of these lifters ensure precision and longevity that exceed any lifter on the market. Other features include increased duration and lift to the camshaft and two oiling features. Another industry first is the fact that the hydraulic element of this patented lifter is serviceable, allowing anyone to rebuild lifters in his or her own garage. Order the Evolution lifters recommended for your year/make and engine application.

COMP Cams Max-Lift BSR Shaft Rocker Systems
COMP Cams introduces another industry first with their Max-Lift BSR shaft rocker systems, a bolt-in bushed shaft rocker system that increases valve train stiffness helping your engine achieve higher levels of performance. By tying all eight rocker arms together on a single shaft that fits in the stock rocker stand, COMP Cams has found a way to improve valve train dynamics, increase valve train stiffness and reduce deflection under extreme loads. The increased valve train stiffness created the BSR rocker system allows your existing cam to act like a larger camshaft by transferring more of the motion to the valve or the use of more aggressive, higher lift cams without losing control of the valve train. Take complete control of your valves with the COMP Cams Max-Lift BSR shaft rocker system.

COMP Cams Short Travel XD Hydraulic Roller Lifters
COMP Cams short travel XD hydraulic roller lifters offer the advantages of both light pre-load and reduced oil volume, producing the most stable and highest-revving hydraulic lifter available. The XD versions feature heavy-duty tool steel pushrod seats. This adds strength and durability in extreme-duty applications, such as turbo drag cars and offshore powerboats. Certain engines respond better to a light lifter pre-load because it recovers more quickly from any bad harmonics in the valvetrain. Others work better with a heavy pre-load because oil volume is reduced under the plunger, which increases lifter stiffness. Now you have the best of both—with COMP Cams short travel XD hydraulic roller lifters. Order the model designed for your vehicle and engine application.

COMP Cams Ultra Pro Magnum Rocker Arms
Utilizing years of valvetrain design experience, the latest FEA stress analysis technology, and an exhaustive testing regiment (dyno and Spintron), COMP Cams engineering team left no detail to chance. Everything from casting techniques to valve spring clearance was scrutinized to ensure that Ultra Pro Magnum rocker arms not only lived up to the lofty standards of their predecessor, but also took stud mount rocker performance, stability, and value to a whole new level. The most noticeable advancement centers around their nearly unbreakable investment cast 8650 chromoly body. The arched, web-like design delivers a nearly 29 percent increase in strength and rigidity, while reducing the moment of inertia and optimizing the dynamic balance. The resulting rockers maximize lift and valvetrain control at high rpm. The increased retainer and valve spring clearances of the new design enable the use of large-diameter valve springs, retainers, and locks, without clearance or fitment issues. The new black oxide exterior finish offers a distinctive appearance, along with long-term corrosion resistance. The COMP Cams Ultra Pro Magnum rocker arms feature an oversized trunnion and precision-sorted needle bearings designed for use with high-load valve springs. These unique rockers also feature hardened roller tips for reduced friction and elimination of the valve stem "side loading" that causes premature valve guide wear.

COMP Cams Sportsman Solid Roller Lifters
COMP Cams Sportsman solid roller lifters feature premium-quality, high-value components designed for sportsman and professional racing, along with high-end street machines. They're available in both needle-bearing and bushing configurations. Each design features two pressurized EDM oil feeds, as well as an edge-orifice feed to the wheel. This delivers a more reliable oil feed than most competing options. COMP Cams Sportsman solid roller lifters are also designed with a shallower oil band than competitors' versions for increased strength and rigidity, while internal machining helps to reduce weight. The body utilizes a skirted wheel that strengthens the lifter ears, and the skirt also provides more contact area with the lifter bore for further lifter stabilization. In addition, staked axles eliminate clips and provide robust axle retention. This feature increases the stiffness of the lifter ears and helps to prevent the ears from spreading. The COMP Cams Sportsman solid roller lifters are built from 8620 premium steel for increased strength and wear resistance and they feature a captured, stainless steel link bar design. The lifters also utilize a tapered and slotted link bar tower for reduced weight and improved aesthetics. Choose the size and options tailored for your engine application.

COMP Cams XD-A Pushrods
COMP Cams's XD-A pushrods offer a game-changing method for accurately setting lash or pre-load while using non-adjustable-style rockers. These patent-pending pushrods incorporate a top section that slides 2 in. inside a wider bottom section, with one or two shims captured in-between. Proven to 9,000-plus rpm in solid roller LS applications, the system provides a 90 percent increase in bending stiffness for enhanced valvetrain stability. It also allows for lightening of a rocker arm system by 30-plus grams on the backside by removing the adjuster and required support area for threads and seating. The use of lighter rockers with XD-A adjustable pushrods allow higher rpm to be achieved by creating a much more dynamically stable valvetrain system. COMP Cam XD-A pushrods are designed especially for engines with low-mass rocker arms and a light valvetrain with drop-in fitment in LS engines. They can be adjusted over a range of .172 in. in .004 in. increments with shims. Choose the pushrods with the adjustment range needed for your setup.
