Spring Retainer Plate
Part No. GM-DA-18

View Instructions

The outermost spring retainer plate in GM 6L80, 6L90 (300mm) damper assemblies often cracks and fails. The OE material and stamping process create an inherent weakness in the highest stress point: the spring cavities.

Sonnax spring retainer plate GM-DA-18 is a direct replacement for damaged OE spring retainers. Featuring reinforced spring cavities and machined from forged steel, GM-DA-18 is stronger and more durable than OE.
