Sonnax Clutch Backing Plates

GM 6L80 and 6L90 transmissions often suffer failure of the 4-5-6 clutch assembly due to flexing and bowing of the backing plate (coning)—especially when your clutch-apply pressures exceed OE specifications. Sonnax clutch backing plates are designed to minimize flexing/bowing when the clutch is applied, drastically reducing the likelihood of clutch plate distortion. Their stiffer backing plate design outperforms OE and aftermarket plates.

XClutch Stage 1 Clutch Kits

XClutch Stage 1 clutch kits offer a variety of performance upgrades for both street and track applications. They are designed in-house and normally utilize a single plate organic, ceramic, or carbon friction disc along with an upgraded factory-style pressure plate. XClutch kits utilize a similar mechanism to the factory clutch, making them ideal enhancements for most vehicles with low to mid-level performance modifications. Stage 1 clutch kits are available in three distinct performance clutch packages—sprung, rigid solid, and steel-backed organic. Features and benefits of each: * 1A sprung organic—this range has been specifically designed for street vehicles that have minor engine and general performance modifications. These kits offer a sprung organic friction disc that allows for great drivability, while offering improved clamping force through the use of a performance pressure plate. * 1G rigid solid organic—with a rigid center version of the organic disc, this range is ideal for street vehicles and light track use. These kits are often available with a lightweight alloy pressure plate and performance flywheel. * 1T steel-backed organic--this range offers a higher burst strength by bonding the organic friction material directly to a steel backing plate. These kits are ideal for high performance vehicles used on the street with occasional track use.

Sonnax Automatic Transmission Oil Pump Bushings

Worn babbit pump bushings in your GM Powerglide, 350, 400, or Allison AT540 transmission can allow the converter hub and inner pump gear to move off-center, thus causing damage to pump gears and the pump housing crescent. You can replace the worn originals with automatic transmission oil pump bushings from Sonnax. These direct replacements have tighter tolerances for improved fit over OE units, and they're lined with highly wear-resistant PTFE to help maximize the life of the older style and increasingly rare pumps. Order the bushings recommended for your application.

Tremec Magnum-F Manual Transmissions

Tremec introduces the Magnum-F 6-speed manual transmissions for fourth-generation Camaros and Firebirds. Designed to replace T-56 transmissions in 1998-2002 GM F-body cars, the Magnum-F leverages Tremec's pervasive TR-6060/Magnum architecture in order to provide fourth-gen enthusiasts significantly improved performance and relief from a shrinking pool of quality T-56 replacement parts. Born in the vacuum created by the release of the original T-56 Magnum (now known simply as 'Magnum') back in 2009, the Magnum-F fills a longstanding void in the overall Magnum line with regard to shifter locations—addressing not only LS1-powered '98-'02 F-bodies, but several other applications that utilize a similar shifter position. Beneficiaries include third-generation F-bodies, LT1-powered fourth-gens, LS-swapped late models of all varieties, and sport compact applications such as A80 Supras, FD RX-7s, and more! Where the original Magnum shifter locations may prove too far forward, and the extended length Magnum XL's too far back, the Magnum-F's in-between position often proves to be just right. Inside, the Magnum-F benefits from the same durable componentry found in many of today's hardest hitting OEM muscle and sports cars. Over the T-56, the Magnum-F transmissions boast increased face-width on all gears, a robust combination of double and triple cone synchronizers, enhanced webbing in the main case, provisions for a cooler circuit, and more! Tremec also took the opportunity to upgrade the shifter to an isolator-type unit, like that found on its Magnum XL. The shifter reduces in-cabin noise and vibrations, while at the same time providing the precise and communicative shift feel that all Magnums are known for. And, like all Tremec aftermarket transmissions, the Magnum-F is made from 100 percent brand-new OEM-quality content. Models with different gear ratios are available. Additional notes: * Close Ratio version for high performance street and road racing * 700 lbs.-ft. of torque capacity * Reasonably light at 135 lbs. dry * Multiple shifter locations and dual speedo pickups for unmatched versatility * Choice of two different gear ratio sets with unique double overdrive ratios * Incredibly short, extremely low-effort shift throws, with crisp, precise engagement * Modern OE supercar technology for the ultimate pro-tourers, road-racers, and more

Sonnax Smart-Tech Direct Clutch Drum and Shaft Kits

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

Sonnax Clutch Apply Piston Kits

Sonnax clutch apply piston kits drastically reduce the likelihood of clutch plate distortion. Due to OE design shortcomings, flexing and bowing of the backing plate is common in some GM transmissions, often causing them to suffer failure of the 4-5-6 clutch assembly. These kits increase the piston-to-plate apply ring surface area to strengthen and reinforce the assembly, along with a more rigid backing plate design that outperforms OE and aftermarket components. Sonnax clutch apply piston kits easily tackle these common weaknesses. Kits include: * Apply piston * Apply ring * Piston dam * Backing plate
