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.
