Sonnax torque converter conversion kits are designed to upgrade the existing torque converter for improved performance characteristics like better acceleration, increased power, and smoother shifting. Many conversion kits focus on changing the stall speed, which is the engine rpm at which the torque converter fully engages, allowing for more aggressive launches or better towing capability depending on the chosen stall speed. Some kits include modifications to improve the lock-up function of the torque converter, leading to better fuel economy at cruising speeds by eliminating slippage. The torque converter conversion kits by Sonnax come with various internal component options, allowing fine-tuning to match your vehicle's specific needs and your driving style.

Sonnax 10-clutch drum kits are optimized for Powerglide performance applications. Using the patented Sonnax 10-clutch drum system, the drum and piston accept 10 frictions and 10 Kolene steels, increasing lockup surface to allow significantly more torque than modified OE drums. The drum features a piston bore that is .060 in. deeper for greater piston travel. Kits include: * Complete 10-clutch drum kit with all related parts, including installed PTFE-coated bushing * Includes ten .060 in. frictions and ten .060 in. thick, 12-tooth Kolene steels * Excess material removed from high-strength, cast steel drum to reduce rotating mass * 6061 forged aluminum piston will not crack at high operating pressure like cast pistons * Forged chromoly steel clutch hub with lightening holes

Sonnax heavy-duty reaction shaft kits are universal to fit all years and all input carriers. Reaction shafts used in high-torque applications, and especially in heavy vehicles, suffer from two common issues that require replacement. The splines that engage the rear planet can twist and the splines that engage the ring gear wear. OE and other aftermarket versions are made from lower strength, plain carbon steel. Sonnax heavy-duty reaction shaft kits are made from high-strength chromoly steel alloy to eliminate spline twist and spline wear. Contents include: * Reaction shaft with bushings * Reaction shaft-to-shell bearing * Reaction shaft-to-front carrier bearing * Shim

Sonnax heavy-duty intermediate overrun clutch outer races eliminate weak points. Race failure is a chronic problem with high-torque loads causing race fractures at two stress points: the radial lube holes and the sharp inside corners at the base of the outer splines. Sonnax outer races are engineered with offset lube holes so rollers never travel directly over the holes, and they are spaced so only one roller is ever positioned near a hole, radically reducing the risk of fracture. Other design improvements to the splines, plus upgraded material and a custom manufacturing process, further improve durability, doubling the torque capacity over any OE or other aftermarket races. Sonnax heavy-duty intermediate overrun clutch outer races are direct replacements offering unrivaled reliability at any power level.

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

Stop worrying about input shaft failure when running the GM Powerglide in the most extreme applications. Sonnax offers the only big input shaft upgrade with custom components designed to work together for reliable performance. Whether you have an existing assembly or start from scratch in the gear ratio of your choice, it's the best way to connect huge power to Sonnax Extreme planetaries for great run after run with minimum downtime. The only way to prevent twist and breakage from massive torque is to increase the input shaft diameter, and the core of the big shaft system is big input shaft kit 353532-01K. The shaft strikes the perfect balance between strength and ease of installation with a 1 1/8 in. diameter and a unique, high-strength spline that still fits through the front sun gear. It delivers 35 percent more strength than standard 1 in. shafts, a dramatic upgrade for racers that want to take full advantage of the lightweight and efficient Powerglide automatic transmission. (Note: The Sonnax big shaft system for Powerglides requires changing to a 35-spline turbine hub.) Kit contents: * Shaft * Clutch Hub Big Shaft features: * Torsional, ringless design * Heat-treated, 300M steel with advanced processing * 35 splines (AOD-style) at converter Clutch Hub features: * 1.500 in. tall hub for use with 10-clutch setups * High-strength chromoly steel * Custom fit for the big shaft

Input housing failure at the shaft and forward piston areas is common in high-torque 4L60, 4L60-E, 4L65-E, and 4L70-E transmissions. Also, the input drum assembly is known to crack and strip out splines where the input shaft is pressed into it (where the overrun piston rides). Sonnax input housing sleeve kits—forward sleeve kits and overrun sleeve kits—when used in combination with each other, greatly increase the maximum strength of the housing for additional torque capacity and can prevent these failures. Sonnax input housing overrun and forward sleeve kits are offered separately. Both sleeves feature high-strength, chromoly construction that increases housing torque capacity by protecting the shaft and either the forward piston or overrun piston areas. Each kit will include piston, reinforcement sleeve, and outer and inner piston seal.
