  • One-piece 300M steel forging is heat treated and shot-peened for maximum durability. This shaft doubles oil flow to the clutch pack for improved resistance to heat and longer clutch life. The hub is designed for use with Powerglide-style, 45-tooth frictions. This shaft is designed for use without OE dampner.

 

The ideal upgrade for performance vehicles with GM 6L90 transmissions, this extreme duty 4-5-6 clutch hub and intermediate shaft 104690-45 guarantees maximum protection against shaft breakage. The unique hub design improves oil flow and accepts Powerglide-style frictions to optimize clutch durability. This shaft uses a much stronger, one-piece design that eliminates the OE assembly’s weak, welded connection. 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. The 4-5-6 clutch is released in 1st, 2nd and 3rd Gears, and at high RPMs, constant oil flow is required across the spinning clutch frictions to prevent heat build-up and damaged clutches. The unique, upgraded design of the hub doubles oil flow to the clutches for significantly more protection against heat build-up and clutch failure.
