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.

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.

Higher rpm, increased boost/drive pressures, and aggressive camshaft profiles can result in valve float and cause serious damage to diesel valvetrains. Valves can also be blown open by higher boost and exhaust drive pressures creating reversion that allows exhaust gas to enter the cylinders on the intake stroke. This re-introduced exhaust gas shields fuel particles from oxygen, delays the start of combustion, decreases cylinder pressure and temperature, and lengthens the time needed to completely burn the fuel … all reducing power. Hamilton Cams valve springs can improve power by allowing higher boost pressures and rpm without valve float or excess reversion. Their single valve springs work well up to 4,500 rpm with moderate-lift camshafts and OEM-size valves. However, as rpm, valve lift, spring pressures, and valve sizes increase, dual Hamilton Cams valve springs are necessary to properly control the valves. For the highest camshaft lifts, they should be used with Hamilton Cams titanium retainers. Note: As a precautionary measure, titanium retainers should be inspected after every season for excessive wear.
