Eaton Detroit Truetrac Differentials
Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque. They perform like a limited-slip differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant. These replacement units are available for dozens of axle applications.

B&M Jeep Precision Sport Shifters
B&M Racing introduces the Precision SportShifter for 2007-18 Jeep Wrangler JK models equipped with the NSG370 6-speed manual transmission. The unit features a CNC billet aluminum case with an electric blue anodized finish which houses internal components made from super tough 4140 chromoly. The shift throw has been reduced by 35 percent over the factory shifter along with the detent pressure which has been significantly increased creating a noticeably stiffer shift feel. This was done to address problems with the softness of the factory shifter detent springs which easily pop out of gear while off-roading. The shifter uses the factory shift stick and knob.

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

B&M Jeep Shifter Stick Assemblies
B&M Jeep shifter stick assemblies are designed specifically for all Jeep Wrangler TJ/JK models with 6-speed manual transmissions and can be used as either a direct-replacement of the factory shifter stick, or as the finishing touch when used with the B&M JK Precision SportShifter. They are constructed from high-strength 4340 nickel-chromoly steel and feature improved bends that provide more shifting leverage and comfort than the factory stick. The stock Jeep shift handle has a thick and soft rubber isolator between the shifter and the stick that reduces transmission noise inside of the Jeep, but degrades over time and results in a very "mushy" feel. B&M Jeep shifter stick assemblies feature a billet aluminum block with four replaceable rubber O-rings that provide isolation from transmission gear noise and also result in shorter, noticeably firmer and more positive shifts. The shift handle is finished off with a durable black e-coat and topped with a black round B&M logo engraved shift knob showing that you take off-road performance seriously. They feature a 3/8 in. x 16 thread pattern so you can also customize the look of your shifter with other styles and colors of shift knobs.
