Heavy Duty Spring Retainer Kit

Sonnax offers heavy duty spring retainer kit GM-RS-1HPK as a drop-in replacement for use in high-end diesel converters. The retainer features 10 sites of larger surface area contact with the stator cam, an improvement over the two, smaller contact sites on the OE retainer. Greater surface area contact enables the Sonnax spring retainer to prevent the common problem of bent or damaged retainers, providing enhanced wear resistance and durability.
