Failure of the intermediate stub shaft and direct drum are almost inevitable when transmissions are pushed to the limit. To maximize durability and improve clutch capacity in heavy-duty/performance vehicles, Sonnax offers Smart-Tech direct clutch drum and shaft kits, the first upgrade to eliminate every critical weakness. Most failures in these units occur where the direct drum and stub shaft connect. Even other aftermarket upgrades that rely on a heavy-duty shaft will sheer in this area under extreme conditions. Unlike two-piece assemblies, the all-in-one Smart-Tech easily handles the highest horsepower/torque levels. The unique one-piece clutch drum with integrated stub shaft is precision machined from high-strength steel to guarantee there are no splines to strip from the drum or weaken the shaft. The shaft itself is significantly thicker and 2 times stronger than the original. Due to its larger diameter, the integrated shaft must be used with the kit's custom, heavy-duty sun gear. Insufficient holding power is another area where many transmissions fall short, but installing thinner aftermarket steels and backing plates to increase clutch capacity isn't ideal. Those components increase clutch pack flex and heat build-up, making them the primary cause of repeat burn-up. To improve both performance and long-term reliability, the Smart-Tech's custom drum and piston hold an OE backing plate and seven OE frictions for 17 percent more clutch capacity than the six-friction stack-up. Sonnax Smart-Tech direct clutch drum and shaft kits feature: * One-piece design that eliminates weak point where drum splines strip and shafts break * Rugged shaft is 50 percent thicker and twice as strong as OE * Custom drum and piston deliver 17 percent more clutch capacity with optimum protection against burn-up * High-strength drum and shaft are precision-machined from hardened 8620 steel * Unique sun gear is precision-machined from 9310, heat-treated steel

The ideal upgrade for performance vehicles with the GM 6L80 or 6L90 transmission, Sonnax extreme-duty 4-5-6 clutch hub and intermediate shaft guarantees maximum protection against shaft breakage. The unique hub design improves oil flow and accepts Powerglide-style frictions to optimize clutch durability. In place of the 2-piece shaft/hub, Sonnax uses a much stronger, one-piece design that eliminates the OE assembly's weak, welded connection. It is custom forged from ultra-high-strength 300M billet steel, and 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.

Note: Systems with Works finish will take on a unique coloring after it goes through a heat cycle on the motorcycle that looks much like those titanium works components Yoshimura's factory racers use. The Works finish is a contemporary satin/matte with uniform heat coloration, increased fatigue strength, and increased scratch and stain resistance benefits.

Sonnax offers a variety of automatic transmission rebuild components, including Smart-Tech overdrive clutch housing kits. Dodge trucks pulling heavy loads or with boosted power are at high risk for overdrive burnup due to the stock transmission's insufficient clutch capacity and fragile OE clutches. Even small amounts of heat and extra torque will push the thin (.034 in.), single-sided clutches over the edge, distorting the clutch pack. The fact is, any distortion of the clutch pack takes the clearance out of spec and makes overdrive clutch burnup inevitable. This Sonnax kit will keep hardworking trucks on the road! The unique billet aluminum housing increases overdrive apply area by 16 percent and holds a physically taller clutch pack. The 2X thicker steels increase clutch pack steel mass by 28 percent for maximum heat dissipation; and the double-sided BorgWarner clutch frictions are optimized for the 68RFE OD application and are custom-made for the Sonnax kit. This guarantees an unrivaled combination of squawk resistance and maximum clutch capacity for any truck. This groundbreaking kit is the only top-of-the-line upgrade that eliminates clutch problems without relying on valve body/pump modifications or adding the expense of extra components. Details at a glance: * Modified housing holds physically taller clutch pack for 20 percent more clutch capacity * 16 percent more OD apply area for firmer, more controlled shifts * 2X thicker steels and double-sided clutches increase steel mass by 28 percent for maximum heat dissipation * Custom BorgWarner clutches for maximum capacity with state-of-the-art squawk resistance * Bolt-on anchor plate eliminates clutch pack flexing and distortion that contribute to heat build-up * Combine with Sonnax line pressure booster kit RFE-LB1 for even higher levels of performance * Contents: -- Overdrive/reverse housing -- Lip seal -- Adapter sleeve -- UD/OD reaction plate -- Steel clutch plates (5) -- Friction clutch plates (6) [custom BorgWarner] -- Anchor late shims (2) -- Bolt-on anchor plate -- Screws (18)
