Consistent transbrake release is mandatory for a successful ET racing effort. To improve transbrake release, rebuilders typically replace the OE return springs with stiffer springs, such as the Sonnax reverse clutch return springs 28320A. These extra-stiff springs can deflect the OE retainer, resulting in a loss of intended load. Sonnax heavy duty reverse clutch spring retainer 28709 is stamped from high-strength, roll-tempered steel. This additional strength resists deflection better than used OE retainers made of mild steel. For optimum reverse clutch release, use Sonnax reverse springs 28320A with the 28709 retainer.
