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.

COMP Cams Valve Spring Locators
As with all other areas in the valvetrain, the area where the spring sits also takes a beating. The old standard shims and/or seats simply will not hold up to the extreme pressures and high rpm found in today's performance engines. COMP Cams valve spring locators solve this problem and eliminate failures.

COMP Cams Camshaft Phaser Disassembly Wrenches
Before installing the COMP Cams 5455 spring limiter tool, it's necessary to compress the variable valve timing spring. These camshaft phaser disassembly wrenches compress the spring—so you can install the 5455 limiter tool and then the 5457 or 5459 phaser limiter plug. Order the wrench recommended for your year/make and engine application.

COMP Cams Pro Magnum Hydraulic Roller Lifters
COMP Cams Pro Magnum hydraulic roller lifters are specifically designed to perform at higher engine speeds. When engines are equipped with a hydraulic roller camshaft, high rpm is limited by the improper positioning of the internal piston, as the lifter inevitably "pumps up." This improper location results in broken valves and, therefore, leads to lost power or sometimes even engine failure. These lifters offer a distinct advantage over standard high performance hydraulic lifters, especially in race applications where a hydraulic lifter must be used.

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 Valve Springs
Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential. It does absolutely no good to install a cam that will perform up to 8,000 rpm if you do not have the correct springs. Use the only valve springs that will give the recommended spring pressure with the valve both on the seat and at maximum lift. COMP Cams valve springs are offered in single and dual styles to meet your cam requirements.
