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.

KB Performance hypereutectic pistons are made from 390 aluminum alloy and heat-treated to T6 standards, which makes them 30 percent stronger than ordinary untreated hypereutectics. Their 100 percent CNC-machined crowns, high upper compression-ring location, gas-accumulator groove, drilled oil returns, and spiral-lock retainer grooves make these pistons outstanding for performance applications. They have a lightweight, rigid-rib skirt design that stabilizes the piston in the bore. All of this adds up to pistons that fit tighter than forged types, provide improved oil control, reduce blow-by, increase ring life, eliminate cold start-up knocking, and won't cost you an arm and a leg! Thousands of models are available—find the set and options designed for your vehicle and engine application.

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.
