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.

Rollmaster Red Series timing sets are lightweight and stronger than any other timing sets available, due to the weight savings of billet steel and use of CNC machinery. All sets feature billet steel crank and camshaft sprockets that have been 100 percent CNC-machined for reduced wear and improved accuracy. Rollmaster Red Series timing sets come standard with a premium grade one-piece Iwis full roller chain, produced in Germany and built to the highest possible quality standards. The sets have nine keyways, allowing you more adjustments for dialing in the camshaft to your liking. Multiple keyways are a solid fixture and tend not to move or work loose like offset bushings or dowels--providing a positive locking of the cam timing to whatever position is desired.

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.

If being able to adjust your cam timing quickly and easily is a top priority, then COMP Cams Ultimate Adjustable billet timing sets could be the answer. They have 2-piece billet steel cam sprockets, which let you change cam timing without removing the degree wheel or releasing the valvetrain load, and there's no cam bushing to break. Timing can be varied from 6 degrees retarded to 6 degrees advanced. Chains are heavy-duty, double-row types with hefty 0.250 in. rollers. A one-piece roller thrust bearing handles unwanted end loads.

Melling timing chain sets are designed for use with either performance or stock cams. They have a solid-bushing chain for a true bearing surface that rolls with the sprockets, eliminating chain stretch. The crank gears are machined from stress-proof steel. Most Melling timing chain sets have three keyways to ensure accurate timing for early or late model vehicles, and to allow you to set the cam timing at 4 degrees advanced, 4 degrees retarded, or stock. However, 50-state (stock replacement) sets have single keyways. The chains are available in several styles, such as single or double roller, single non-roller, and link belt. Melling timing chain sets are not for use above 6,500 rpm. Order the model designed for your vehicle application.

S&S Cycle roller rocker arm complete rebuild kits offer several benefits for Harley-Davidson® motorcycles, including significantly reduced friction on the valve stem, improved valvetrain longevity, increased horsepower potential, especially at higher rpm's, and smoother engine operation. These kits also offer better compatibility with high-lift cams due to the reduced wear and side load on the valve stem from the roller design; essentially providing better overall performance and durability compared to stock rocker arms. Order the rebuild kit designed for your HD® model. Features and benefits: * Complete kit includes roller tips, roller pins, roller pin retaining clips, and rocker arm bushings to rebuild a set of four S&S forged roller rocker arms * Designed using Finite Element Analysis (FEA) and forged from 8620 steel for strength * The roller design minimizes friction on the valve stem, leading to less wear and tear on both the valve stem and rocker arm, extending the lifespan of the valvetrain components * The roller bearings in the rocker arms distribute the load more evenly, leading to better wear resistance compared to traditional sliding contact on stock rockers * Roller rockers are designed to handle the increased valve lift associated with performance cams without excessive wear or stress on the valvetrain * Rocker geometry is better suited to high-lift camshafts * Bushings are longer than stock, increasing the time between rebuilds * The smooth rolling action of the roller bearings can contribute to a quieter engine operation * Compatible with stock or S&S CNC-machined heads * Many high-quality roller rocker arm kits are designed to be serviceable and rebuildable, allowing long-term use with proper maintenance Notes: When installing roller rockers, it's important to choose a camshaft that is compatible with the increased valve lift capability. Also, precise installation is crucial to ensure optimal performance and avoid potential issues.
