Other aftermarket solutions typically employ a thinner backing plate, and thinner steels which ultimately exacerbate the problem. Sonnax heavy duty 3-4 clutch backing plate kit 74140-01K significantly reduces backing plate flex for increased 3-4 clutch durability. It features a significantly thicker and stiffer backing plate, used together with a thinner (yet stiffer) apply plate.
Designed for use with GM high energy clutch pack with seven. 095 steels, this kit can be used to upgrade OE 700-R4 and 4L60-E five-friction or six-friction clutch packs to seven frictions, or to improve stock, seven-friction clutch packs in 4L65-E and 4L70-E units by reducing backing plate flex. Backing plate is significantly thicker and stiffer than OE for added durability.
