An essential upgrade for any hard-working GM 6L80 transmission, this Sonnax heavy duty 4-5-6 clutch hub and intermediate shaft guarantees maximum protection against shaft breakage and clutch failure in any vehicle pushing stock components to the limit.
The one-piece design is custom forged from ultra high-strength 300M billet steel, then heat treated and shot peened for added durability. This combination of features guards against broken 4-5-6 hubs and the risk of rear splines shearing off — chronic failures in performance cars and trucks as well as heavy commercial vehicles.
