Using the highest quality TCI manufactured components, each Street Rodder package is equipped with an automatic valve body and valve body performance improvement kit that allows you to achieve firmer, yet not too harsh shifts in the vehicle while remaining fully automatic and retaining the stock shift pattern. Each Street Rodder transmission and torque converter undergo the industry-recognized triple testing to verify that internal fluid pressures and shift characteristics match the strict TCI quality control standards. Torque converters are tested to maintain that the impeller body and pump drive hub remain true and are then pressurized and lead tested to confirm the integrity of the weld seams. Finally, each unit is computer balanced to reduce drivetrain vibrations that can cause serious damage to your converter. For street cruisers who want excellent street performance and lasting durability, the TCI Street Rodder transmission packages provide the prefect solution.

Boss Hog Street Bandit Torque Converters

Torque converters are considered one of the most mysterious mechanical components in today's vehicles. They function like a clutch, and keep the engine running even when the vehicle comes to a halt. By designing the stall speed to match both the engine and desired stall speed, ACC Performance converters help low-end idle speeds, improve performance, and acceleration. ACC Performance Products has emerged as an out-right leader in torque converters and here's why: * Boss Hogs are welded, not furnace-brazed; furnace brazing is not the best way to adhere torque converter components, it will erode and ruin the stators and all rotating parts * Industrial Torrington bearings handle more torque than smaller, uncased needle bearings * Aircraft aluminum washers instead of fiber washers put more horsepower and torque directly to the ground * ACC converters are hand-built and tested to ensure that you get the best converter money can buy * With returns below one percent, you are assured of the highest quality parts available * Street Bandit converters are designed to handle as much as 650 hp * Custom-engineered turbine hubs maintain the highest quality, strength, and durability * Stators are built with high-flow vents and channels for greater cooling to handle greater power and higher temperatures * Engineered with a single bolt pattern that makes ACC converters surprisingly light to free up your motor and allow it to gain rpm quicker Notes: * Boss Hog Street Bandit torque converters are not designed to handle the extreme shock and abuse of nitrous oxide or trans-brakes * It is imperative that a transmission cooler be added with any torque converter that is rated over stock stall speed

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
