Nothing is tougher on a torque converter than putting it behind a blown fuel engine. Made for supercharged engines, ATI Fuel & Blown torque converters are designed for the ultimate in high-horsepower holding for big cubic inch nitrous or supercharged engines. They feature a special 22-element sprag with double-cage construction to simultaneously control each sprag element. The sprag sits in concentric races that are heat-treated to 65 on the Rockwell C scale. A specification sheet must be filled out prior to ordering.

The downsizing of modern passenger car engines enables reduced fuel consumption and CO2 emissions, but can also increase rotational irregularities and natural vibrations. Torsional vibrations transmitted to other components in the drivetrain diminishes comfort and may even lead to component damage, therefore effective vibration damping is essential. LuK dual mass flywheels (DMF) reliably dampen torsional vibrations in the powertrain and ensure high gearshift and driving comfort in all speed ranges. Unlike a conventional flywheel, DMFs consists of two masses which are mounted to rotate against each other. A damping system in the form of arc springs is integrated to almost completely absorb the torsional vibrations of the engine. Precisely matched to the respective vehicle, each LuK DMF enables low-speed driving and ensures lower fuel consumption, as well as reduced emissions. Order the proper size for your vehicle.

Not all multi-disc converters are created equal, and with BD Diesel's Triple Torque Force, less is more. To start, BD's in-house CNC-machined cover is designed as one piece, which prevents warping, improper balancing, and leakage. With this design, BD was able to maintain the factory height, thus eliminating the crowding of the pump and the possibility of premature wear. BD Diesel has engineered the dampener for better balancing by riveting it in place, eliminating welding, which can cause warping and affect balance. Each dampener spring is hand-picked to ensure softer engagement. They added notches to the clutch material to prevent fluid adhesion, thus ensuring that even in fluid coupling, the clutches will always have lube. They offer tighter engineered tolerances and a self-centering, 36-external/32-internal, trapezoid-shaped clutch tooth design that enables more contact surface to ensure that the clutch plates properly align, resulting in less friction wear, a longer converter life cycle, and firmer drivability. The clutch plates are also precision-ground flat for smooth operation and consistent wear. Not only will these converters last longer, but they also have 3 times the torque-holding capacity! Triple Torque Force converters come with BD's engineered cast aluminum X-Stator that has fin lengths, angles, and curvatures that are designed to deliver a fluid coupling engine rpm transfer of up to 95 percent, vs. 75 percent with stock stators. This efficiency reduces engine temperatures, increases fuel economy, and better matches the torque curve of the engine, resulting in more torque and horsepower being delivered to the ground. The overall weight of the BD Diesel Triple Torque Force converters has been reduced by 12 lbs. compared to the competition, resulting in better fuel economy and less wear and tear.

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
