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

HushMat Complete Vehicle Insulation Kits

HushMats complete vehicle insulation kits serve two important functions: reducing thermal transfer into your interior, and reducing the noise level by up to 15 decibels. Your engine, headers, manifold and exhaust generate tremendous heat that transfers to the metal firewall and floor—forcing your A/C system to work harder to maintain a comfortable environment. HushMat auto heat shield is proven to lower this temperature by over 40 percent. At the same time, when you drive on the highway at 65 mph, most vehicles approach 80 to 90 decibels of noise. That's like a vacuum cleaner or garbage disposal running on your passenger seat. These insulation kits use a specially designed sound deadening material to deliver a more peaceful ride. Each kit is packaged specifically for your vehicle to provide 100 percent insulation coverage—no holes in the material and no puzzle pieces to assemble. Treat your firewall, doors, floor, tunnel, rear wheel wells, trunk floor, and roof with these HushMat barriers. Order the complete insulation kit designed for your specific vehicle. Additional details: * Reduces road noise and vibration, low-frequency noise from 0 to 1,000 Hz * Stay warmer in the winter and cooler in the summer; withstands ambient temps from -30 up to +550 degrees F * Lightweight and super flexible mats; less than 1/8 in. thick and 0.47 lbs. per sq. ft. * Adhesion is guaranteed; no alcohol or acetone wash needed; no tools required * Trims easily with standard razor knife or household scissors * Self-adhesive peel-and-stick; no glue required * Outperforms closest competitive brand by over 40 percent * OEM approved; meets or exceeds auto damping specs GMO 149M – General Motors; WSB-M5G58-A1 – Ford; and MS-CD 629 Type C – Chrysler
