The unique hub design improves oil flow and accepts Powerglide-style frictions to optimize clutch durability.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003eIn place of the two-piece shaft\/hub, Sonnax 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 and trucks as well as heavy commercial vehicles.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp\u003eThe 4-5-6 clutch is released in 1\u003csup\u003est\u003c\/sup\u003e, 2\u003csup\u003end\u003c\/sup\u003e and 3\u003csup\u003erd\u003c\/sup\u003e Gears, and at high RPMs, constant oil flow is required across the clutch frictions to prevent heat build-up and damaged clutches.
