Sonnax Smart-Tech Drum Modules

Sonnax Smart-Tech drum modules for racing GM TH400 transmissions improve on-track performance and consistency, leading to quicker ETs, more wins, and greater reliability. The TH400 is preferred for its overall durability and multitude of available ratios, but is known to be heavier and less efficient than the popular two-speed Powerglide. Part of the TH400 inefficiency results from the fact that the direct drum counter-rotates, spinning backwards in 1st gear, brakes to a complete stop on the 1-2 shift, then goes from 0 RPM to input RPM on the 2-3 shift. Significant energy is wasted through this cycle that robs power, upsets traction on the shifts, and contributes to broken internal parts. Compared to aluminum direct drums, the Smart-Tech drum module reduces the weight of the counter-rotating components by over 3.3 lbs.! And more significantly, because the weight of the Sonnax counter-rotating parts is closer to the centerline, there's a 68 percent reduction in energy required to stop and restart during the 1-2 and 2-3 shifts. The benefits are increased wheel horsepower, better acceleration, less shock on the shifts, and improved durability. * Complete kit (34555-01K) replaces both forward and direct drums and includes everything from intermediate sprag to the pump; a selection of Sonnax input shafts is available separately. * 100 percent new content, no used core pieces * Includes larger-diameter, 36-element sprag and sprag race that works with OE intermediate clutches * Includes six-friction forward clutch pack and seven-friction direct clutch pack Contents: * Forward Piston Housing * Forward Piston * Forward Piston Return Springs (16) * Forward Spring Retainer * Forward Snap Ring * O-Ring 1.674 in. * Lip Seals (2) * Direct Housing Assembly * Direct Piston * Direct Piston Return Springs (26) * Direct Spring Retainer * Direct Snap Ring * O-Ring 2.737 in. * Sprag Shaft * Front Sprag Retainer Plate * Heavy-Duty Sprag 36 Element * Outer Sprag Race * Rear Sprag Retainer Plate * Sprag Retainer Screws (4) 6-32 x 5/16 in. * Quad Ring Seals (2) * Anti-rotation Seal Rings (2) * Drum * Pressure Plate * Outer Snap Rings (4) * Bearing Small * Forward Clutch Hub * Bearing Large * Direct Clutch Hub * Steel Clutch Plates (4) .060 in. * Steel Clutch Plates (11) .077 in. * Friction Clutch Plates (13) .080 in. * Clutch Separators (60) .103 in.

South Bend Clutch Stage 3 Drag Race Clutch Kits

South Bend Clutch Stage 3 drag race clutch kits are powerfully built with heavily modified vehicles in mind—particularly those built for 1/4 and 1/8 mile tracks. They include a single mass SFI-approved flywheel with each kit, which is typically required for drag racing when the original design is dual mass. The pressure plate is race cover engineered to keep the clutch pedal travel short and quick. South Bend Clutch Stage 3 drag race clutch kits are recommended for drag racing, pulling, and drifting. Order the clutch kit recommended for your specific vehicle and engine size. Features, items, and specs include: * Puck-style disc reduces rotational mass and is assembled with all high-carbon components for maximum strength * Graphite-impregnated ceramic friction material perfectly suited for drag racing (maximum friction co-efficient, rapid heat dissipation, and abrupt engagement characteristics) * Meticulous processing and advanced packaging materials

South Bend Clutch Stage 2 Drag Race Clutch Kits

South Bend Clutch Stage 2 Drag Race clutch kits are designed with racers in mind. They include a single mass SFI-approved flywheel with each kit—typically required for drag racing when the original design is dual mass. The heavy-duty pressure plate is modified for a puck-style disc with no cushion between the linings to keep the clutch pedal travel short and quick. These South Bend Clutch Stage 2 Drag Race clutch kits are recommended for drag racing, drifting, and limited street use. Order the kit that's recommended for your specific vehicle and engine size. Features, items, and specs include: * Graphite-impregnated ceramic friction material for exceptional durability, heat transfer, torque capacity, and reduced chatter * Puck-style disc reduces rotational mass and total drive surface area, while increasing psi on the surface of the friction material * Disc design minimizes inertia, accelerating the transfer of torque from the engine to the wheels * Meticulous processing and advanced packaging materials

South Bend Clutch Stage 2 Daily Driver Clutch Kits

South Bend Clutch Stage 2 Daily Driver clutch kits are engineered for vehicles with high performance modifications. The heavy-duty pressure plate has an increased clamp load with little or no increase in pedal pressure to offer stock feel, while increasing strength and durability. The organic disc material has a high metal content that increases the co-efficient of friction by two times over a stock lining. This greatly increases rotational strength up to a 12,000 rpm burst point for high performance. South Bend Clutch Stage 2 Daily Driver clutch kits are recommended for daily performance, street, and moderate race vehicles. Select the kit designed for your application needs.

ARB Air Locker Differentials

A 4x4 and traction go hand-in-hand; however, standard (open) differentials allow each wheel to turn independently to eliminate binding in turns. Off-road, this becomes a problem as engine power takes the path of least resistance—to the wheel with little or no traction. Limited slip differentials offer some improvement, but too often the slipping is not "limited" enough to maintain forward progress. Automatic locking differentials also have disadvantages; noisy when disengaging, they can also upset on-highway driving characteristics. Created to provide traction on demand, without sacrificing highway driving performance, ARB Air Locker differentials employ a 12 V ARB air compressor (sold separately) to pneumatically operate a solid and durable locking mechanism inside the differential. When activated, the Air Locker prevents the differential gears from rotating and the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like a conventional open differential. ARB Air Lockers are available in over 100 configurations for a wide range of vehicles and can be installed in both front and rear axles. Installation should be performed by a qualified differential technician, although no special tools or skills are required, apart from those necessary for fitting a standard differential. ARB also offers three compressor models suitable for Air Locker operation, two of which can be used to inflate tires and operate other equipment. Additional features of ARB Air Lockers include: * Vastly improved traction means less reliance on momentum, reducing the likelihood of vehicle damage * Easy, convenient operation without leaving the comfort and safety of the driver's seat * Ultra durable and extremely strong; only the highest quality materials used in construction * Patented gear technology and 2-piece design ensures optimal locking strength * Forged gears provide superior strength and durability * Incredibly simple, yet effective, design employs minimal moving parts for maximum reliability * Thoroughly tested and proven * Most sold as kits with differential, activation switch, solenoid valve, air line, and bulkhead fittings * Front and rear Air Lockers available for most makes and models * For 4WD and 2WD applications * Easy maintenance; no special additives required * Also offered in ARB Traction Packs that include two Air Lockers, a compressor, and accessories for tire inflation
