FTI Performance SST Series Torque Converters

FTI Performance SST Series custom-order torque converters are available for use with a variety of transmissions, including Powerglide, THM350, and THM400. The 9 in. units are used by top drag racers. A torque converter is what transmits torque from the engine to a rotating driven load. It's a type of fluid coupling which allows the engine to spin somewhat independently of the transmission. SST Series torque converters are available with a 0-blade stator for a turbo spline, or the looser 6T stator model.

TCI Competition Torque Converters

TCI Competition torque converters are proven race winners and an excellent choice for stock and Super Stock cars. They work well with both big and small blocks, producing power between 4,500 and 7,000 rpm. You'll maintain engine rpm between shifts with their efficient design, and gain improved reliability with an oversize caged bearing supporting a new stator. ETs are more consistent and reaction times faster as a result of a stronger housing, which resists flexing and ballooning.

Sonnax Extreme-Duty Clutch Hub and Intermediate Shaft Assemblies

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.

RevMax Billet High Performance Towing/HD Valve Bodies

RevMax billet high performance towing/HD valve bodies for a variety of applications, including many Dodge and Ram trucks from the early 2000s and up. The V2.0 is 1 in. thick, but this new version has precision cutouts that allow the use of a stock filter and pan. Unlike other designs, full depth worm tracks in crucial circuits are included. Other competing designs have only a .190 in. deep worm track in several critical circuits. One restricted circuit is the combined vent track, responsible for all venting operations and in particular the problematic SSV valve. The next restricted circuit is the torque converter clutch signal circuit. Restrictions in this circuit create all kinds of torque converter related concerns, including dragging when coming to a stop, overheating, soft or harsh TCC apply or release, and back feed issues resulting in P1776 and P0871 trouble codes. Both the original and V2.0 have nearly full depth worm tracks in these areas which eliminate problem issues! The V2.0 plate will work with ANY aftermarket transmission pan, as well as with stock transmission pans. There is no need to alter any part of the pan or use special filters. Just install it like you would a stock channel plate and go. Order the model recommended for your year/make and transmission application. The RevMax 68RFE V2.0 ZeroFlex billet valve body features the following: * 6061 billet aluminum construction * Deep critical worm tracks * .0003 flatness across the entire plate. The only truly flat billet channel plate! * Micro-polished worm track surface. There are no visible or perceptible machining marks or stepovers. This ensures no chance of any leaking due to machining marks * Large radius machining on the filter cutout increases rigidity yet allows the use of a stock filter assembly * Angle milled step downs increase rigidity in problematic flexing areas * Ability to run up to 325 psi of line pressure without any warpage! (transmission tuning, TCM upgrade or pressure box is needed) * No pump modifications required for up to 250 psi * Proprietary worm track layout * Shortened shift times for crisp, clean shifts * Upgraded valve body to case seals * Billet steel SSV solenoid switch valve and end plugs * Revmax triple double 3/2 billet accumulator pistons with dual seals * Upgraded grade 8 custom fasteners * Upgraded steel accumulator housing plate that is 3x thicker than stock * RevMax proprietary accumulator springs for improved 3-4 shift feel * RevMax proprietary separator plate with the bonded gasket that eliminates cross leaks and warpage issues * Revmax proprietary upgrades * Mounting surface verified and flat filed * Threads checked and repaired if needed * Computerized testing on state-of-the-art $125k valve body test machines

Sonnax Big Input Shaft Kits

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.

Lakewood Safety Bellhousings

Lakewood safety bellhousings are designed for maximum performance and durability. They are cut on CNC 5 axis laser cutters rather than plasma cutters to improve finish quality, reduce heat damage and warpage from the plasma cutter, improve speed of manufacture, and make them all exactly the same. All bellhousings feature a scalloped plate on the bottom of the transmission surface made from G70 grade steel (70,000) psi which will help eliminate stripping the transmission bolts. The engine plates are made of H60 grade material and the bells are roto-brated after welding to relive any stresses created from the hydro forming, annealing, or welding process prior to machining and painting. The roto-brating process also closes the metal on the outer surface making them stronger. Ever wonder how the SFI tests bellhousings like these Lakewood safety bellhousings? First, they bolt the bellhousing to a machine with a cast iron flywheel and saw inside it. Then they spin the flywheel, causing the saw to cut through it until it explodes. If the bellhousing can contain the explosion, the bellhousing is approved. These safety bellhousings are a safeguard to minimize the destructive effects of such an explosion. Don't take unnecessary chances with your safety and the safety of innocent bystanders--Lakewood not only provides top-notch products, they also provide peace of mind.
