COMP Cams short travel hydraulic roller lifters have been engineered from a patent-pending design that specifically performs at higher engine speeds. They're designed to limit the lifter's internal piston as it is pumped up. By limiting that movement, the COMP Cams short travel hydraulic roller lifters cut down on the loss of power and limit valvetrain failure at higher rpm. The lifters are REM-finished and then black oxide coated for extreme durability, even for those high-revving engines. Choose the size, quantity, and other options tailored for your high performance application.

Dove Manufacturing offers valve spring locators, both inside and outside shoulder types, in a variety of thicknesses and diameters. Valve springs require installation at a certain height to function correctly, and you can use a set of shims to achieve this. But that will not eliminate unwanted motion in the spring. Using these steel valve spring seat locators will allow the valve spring to maintain its designed location, without dancing around on the surface of the cylinder head and possibly damaging it. Order a set of 16 in the size needed for your application.

Clevite H-Series rod bearings were developed primarily for use in NASCAR type racing but are suitable for all types of competition engines. These H-Series bearings have a medium level of eccentricity, high crush factor, and have hardened steel backs and thin overlays. They also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating. Bearings with .001 in. extra clearance are available for standard size shafts and with or without dowel holes. H-Series bearings are recommended for use with crankshafts that have oversize fillets and where engines run in the medium to high rpm range. They should also be used if contact patterns obtained with Clevite P-Series bearings are too narrow. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface.

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.

Kibblewhite makes these lower collars to keep your valve springs perfectly in place. The lower collar provides a seat for the valve spring to keep it from moving around, causing excessive wear to your engine or the spring itself. These collars are machined to the highest standards out of either 7075-T6 aluminum or precisely controlled, heat-treated steel, depending on the application, to provide the best results. Don't miss out on a small item that can have a big impact--upgrade to these Kibblewhite lower collars when you are upgrading the rest of your valvetrain.

ATS Diesel Performance valve spring kits feature a conical design that provides more valve control than a standard straight spring. The conical shape allows for a smaller and lighter spring retainer that is also stronger due to size reduction. Unlike other valve springs on the market, ATS valve spring kits can be used on a wide range of trucks, from stock all the way up to competition builds making 2,000 horsepower. Each spring is computer load mapped and matched within 1 lb. of seat pressure followed by a stress relief process to ensure quality and long-term reliability. For a one-and-done upgrade that will allow you to modify your engine to support more power down the road, the smart choice is ATS Diesel Performance valve spring kits.

Mahle Original piston ring sets are designed to be installer-friendly. They are pre-lapped to seat immediately, virtually eliminating break-in time. Ring materials and coatings, as well as ring tension, are all optimized for reduced friction and extended life in each application. The compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining to enhance contact. The CP-20 oil ring assemblies feature a 20 degree ear angle, an exclusive feature that provides the best possible side seal against the cylinder wall, and a special chemical polish on the oil ring expander offers enhanced oil drain back. Mahle Original piston ring sets provide unmatched quality and ease of installation, making them the rings of choice for today's engine builders.
