Factory driveshafts are made from a smaller tube (there are 2 different types) and will flex and bend during hard acceleration, causing the rubber drives to wear out prematurely. The Driveshaft Shop torque tube driveshafts are made from 3 x .125 wall 6061 T-6 aluminum and uses The Driveshaft's own custom machined ends. This ensures that the shaft will not distort or break like the factory units, and offer units rated up to 1000 hp. Choose the driveshaft designed for your vehicle.

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

XClutch Stage 2 clutch kits offer performance upgrades for both street and track applications. Designed in-house, XClutch utilizes the latest ceramic technology in their Stage 2 kits offering either a cushioned or a sprung-style friction disc. They are mated with a high performance pressure plate and are recommended for vehicles requiring a higher level of torque holding and heat capacity. Features: * 1C cushioned ceramic—the discs offer a dampening layer between the two friction surfaces which is clamped together as the force of the pressure plate is exerted on the disc. This dampening along with a sprung hub offers drivability despite the ceramic friction surface. These kits are ideal for track cars that require some drivability or very high-horsepower street vehicles that require the added heat capacity of the ceramic friction material. * 1B sprung ceramic—these friction discs offer a sprung center to allow for drivability and are specifically designed for track use with minor street use. The kits offer great heat capacity due to the ceramic friction material and are available for a wide range of performance vehicles.

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.
