PAC Racing 600 Series Valve Spring Retainers

PAC Racing 600 Series valve spring retainers are the latest developments from PAC Racing Springs. These retainers feature ultra-lightweight designs from proprietary valve spring-type alloys. PAC Racing's sophisticated processing, such as micro-polishing and Nano Peen technology, are used to enhance retainer life. The high hardness of the steel provides higher wear resistance properties to offer superior abrasion resistance and improved fatigue strength, while also reducing weight. PAC Racing 600 Series valve spring come with a reduced step and need to be combined with a matching seat (where applicable) to optimize the performance of the valvetrain.

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 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 Cam Phaser Limiter Kits

Comp Cams cam phaser limiter kits are specially designed, computer-controlled cam gears that automatically optimize camshaft timing based on the current engine rpm Engine oil is pressure-fed to the phasers through passageways in the cylinder heads and cams. The engine computers control solenoids that adjust this oil flow into and out of the phasers' control chambers, creating the ability to retard the cams. While this technology provides fuel efficiency and the ability to always be in the best position for maximum power, regardless of engine rpm, it does present some limitations when it comes to performance cams. With such a wide range of valve timing movement, there is very little piston to valve clearance, which limits you to small cam profiles with little overlap. COMP Cams cam phaser limiter kits restrict the range of cam timing movement (14 degrees for Chrysler, 20 degrees for Ford, and 22 degrees for GM), thus providing the necessary valve clearance for serious performance cams with tighter lobe separations--all while utilizing the benefits of VVT technology. Gain some serious upper rpm power without sacrificing bottom end or mid-range performance with Comp Cams cam phaser limiter kits.

Cloyes Hex-A-Just Timing Sets

With Cloyes Hex-A-Just timing sets, infinitely adjustable cam timing is as simple as turning an Allen wrench. Consisting of SAE 1144 billet steel cam and crank sprockets and a true roller timing chain, these timing sets use a special hex-head bushing installed on your cam's dowel pin. This bushing lines up with degree marks on the cam sprocket. You can adjust timing in fractions of a degree (as much as +/-6 degrees) by loosening the cam bolts and turning the bushing with an Allen wrench. Cloyes Hex-A-Just timing sets install under your stock timing cover and can be used in align-bored blocks. Order the model designed for your vehicle and engine application.

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.
