Make some noise with Edelbrock Rollin' Thunder hydraulic roller camshafts. Designed to improve horsepower and torque, they feature more aggressive profiles than conventional flat-tappet hydraulic cams without excessive valve overlap. Recommended for high performance street and strip use, Edelbrock Rollin' Thunder hydraulic roller camshafts work best from 1,500 to 6,500 rpm and are performance matched to Edelbrock Total Power Package components for proven performance. Features Include: * Performance--roller camshafts generate higher lift velocity and faster valve action for increased horsepower and torque gains * Drivability--produces great sounding idle with excellent vacuum at idle * Durability--the smaller surface contact area of roller tappets and their reduced friction, together with stronger camshaft material (hardened steel or iron) ensures longer camshaft life * Environmental--can use ILSAC GF-4 oil, which lowers emissions and does not require zinc or phosphate oil additives * Economy--reduced contact friction between the lifter and camshaft can increase fuel economy for better mileage

Melling camshaft phasers (aka, sprocket actuators or variable valve timing sprockets) are constructed from high-quality durable steel and shipped with the mounting bolt that attaches the camshaft phase to the camshaft. Sprocket actuators adjust the timing of the motor to ensure that you get the engine power you need, when you need it. The actuator dials the timing back when you don't require the additional power, restoring fuel economy and maintaining engine efficiency. Melling replacement camshaft phasers meet or exceed OE specifications for precise fit and function in their recommended application.

BTR Delphi Gen V hydraulic roller lifter sets are designed for GM's Gen V (LT) and many Gen III/IV LS-series V8 engines to improve valvetrain reliability, particularly for performance builds or AFM/DOD conversions. These lifters are a high-quality upgrade from stock, offering greater durability and a roller wheel that rides on the camshaft, reducing friction and wear to allow for more aggressive camshaft profiles. Additional details: * A great service kit for your worn-out LT AFM lifter set on that AFM conversion * Lifters will also work with Gen III and Gen IV LS engines by using a .025 - .050 longer pushrod * Comes with BTR-exclusive handy soaking and storage trays * Hydraulic Roller Design: They feature a roller on their base that follows the camshaft lobe, reducing friction and wear compared to older flat-tappet designs. * Engine Compatibility: While branded as "Gen V," these are widely used in Gen III (LS1, LS6) and Gen IV (LS2, LS3) LS engines, as well as Gen V (LT) engines, often for performance builds or when deleting the Active Fuel Management (AFM)/DOD system. * High-Quality: Delphi lifters are considered a reliable and durable component, and the BTR version includes upgrades like a high-strength tool steel body and upgraded axle. * Installation Assistance: BTR's trays help with the necessary step of removing the stiff packing grease and soaking the lifters in oil before installation. * Benefits: -- Improved Durability: They offer increased strength and durability for high-performance applications -- Reduced Friction: The roller design minimizes wear on the valvetrain and camshaft -- Valvetrain Overhauls: They are ideal for cam swaps, top-end rebuilds, or replacing worn AFM/DOD lifters

If you're looking for a cost-effective camshaft solution to delete that pesky DOD—Chevrolet Performance stock replacement non-DOD camshafts are the answer. They're designed to work with OEM valve springs/pushrods in the DOD-equipped Gen 4 trucks. These OEM camshafts are standard equipment on non-DOD 5.3L trucks. Since they come as a single-bolt style, new timing gear won't be necessary. Just swap cams and additional DOD delete parts (sold separately) and you're ready to roll! A fairly stock truck shouldn't require dyno tuning; however, the DOD system must be disabled in ECU for proper functionality. It is advised to consult with your tuner for more information. Order the model recommended for your year/make and engine application. Additional features include: * Hydraulic roller tappet cam * Single-bolt camshaft gear attachment * Computer-controlled compatible * This is the camshaft only (other components sold separately)

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.

Many engines use a timing chain, which joins the crankshaft to the camshaft, providing precise valve timing control. Worn and stretched chains can lead to catastrophic engine failure. Fortunately, INA timing chain kits offer the necessary parts to keep your engine running in perfect timing. Along with the chain and chain protection additive, most kits include new tensioners, guides, and sprockets. Order the model recommended for your vehicle application.

The COMP Cams XFI SPR Ford 4.6L/5.4L modular 3V (Springs & Phaser Mods Required) camshafts are the best way to achieve the most power and torque increases possible with the popular Ford Modular 3V engine. These designs are the next step up from the COMP Cams VSR (Valve Springs Required) cams. When compared to the VSR cams, the SPR cams offer additional mid-rpm power increases as well as substantial power gains in the higher rpm ranges. In addition to increases in horsepower, you can also expect another 800-1000 rpm of useable engine speed and an awesome sounding idle lope to match. To achieve this extra level of performance, lobe profiles and timing events were specifically designed to work with the factory variable cam timing (VCT) system cam phasers for all 2005 and newer Ford Modular 3V engines. These cam phasers were modified with the required COMP Cams Cam Phaser Limiter kit to restrict their movement to no more than 20 degrees. This simple modification gains additional piston to valve clearance, allowing for much larger cam designs. This results in cams that not only maintain low and mid-range power, but have incredible high rpm performance as well, all while maintaining the benefits of cam phasing. As noted by the COMP Cams engineering staff during extensive dyno testing, these camshafts provided the biggest power and torque improvements of any cam series they've ever tested in the Ford Modular 3V engine.
