Direct Clutch Drum & Shaft Kit
The Smart-Tech direct clutch drum and shaft kit introduced last year by Sonnax is a critical upgrade for any driver pushing the limits of stock AODE, 4R70W components. By popular demand, this revolutionary kit is now available in two gear ratios: the original 2.84/1.55 and — new for 2020 — the numerically lower-ratio 2.40/1.46 ideal for higher power, dedicated racing vehicles. The lower ratio helps keep performance engines in the optimal power band while allowing a longer pull in first and second gears, improving consistency and performance.
