Spicer Drivetrain Products Axle Shafts

Spicer Drivetrain Products axle shafts are manufactured to the same high standards as factory parts because they are original equipment. That means when an automotive axle is replaced with a genuine Spicer part, you're getting the same performance and reliability as when the vehicle rolled off the assembly line. Dana is constantly revolutionizing the technology behind its Dana axles and Spicer products—so the replacement axle shaft you purchase today may even exceed the standards set for the original equipment part you're replacing. Order the model designed to fit your application.

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

Auburn Gear Select-A-Loc Differentials

Auburn Gear Select-A-Loc differentials maximize your vehicle's traction with on-the-go system engage. These electronically controlled traction-enhancing differentials are selectable lockers offering the traction control of a limited-slip differential and a full-locking differential--all in one! When locker switch is off, the clutch pack activates the limited-slip mode. As torque increases, the separating forces within the differential gears increase, causing the clutch pack to be compressed, in turn providing bias torque to the highest traction wheel. When the locker switch is turned on, electronic current is sent to the electromagnetic coil which locks the axles together. Auburn Gear Select-A-Loc lockers feature a unique cone-clutch design with gearing made from aircraft-quality 9310 heat-treated billet steel for tough-as-nails strength. The lockers operate quietly without any shift fork or pins to line up to change the locker mode. With a limited-slip mode for on/off-road excitement and a true locker mode for the quarter-mile or nasty off-road terrain, Auburn Gear Select-A-Loc differentials deliver superior traction capabilities on the street, at the track, or off-road.

ARB Differential Covers

When off-road, encountering obstacles and hazards that could inflict expensive damage to your differential is inevitable. ARB differential covers are made from high-tensile strength nodular iron (tougher and harder than carbon steel); they are engineered to protect the differential and ring and pinion from off-road hazards. Available for a select line of differentials, they are offered in red or black powdercoated finishes. Features of ARB differential covers include: * Computer-optimized, cross brace design increases the structural rigidity of the entire axle * Helps keep the ring and pinion gears meshing on the flat faces of the teeth--greatly increasing ring and pinion life and overall strength * Top-quality, rare earth magnets on both the drain plug and dipstick collect metallic particles * Dipstick magnet allows the oil to be checked for tell-tale signs of internal damage * Prolonged carrier bearing life (especially on high-output vehicles) from improved support of bearing alignment * Approach/departure angles optimized by angled exterior surfaces that minimize hang-ups * Unique dipstick/filler cap design allows differential oil level to be adjusted for rotated differential housings * Low-profile drain plug resists damage from obstacles * High-strength cap screws (included) are recessed into the cover for impact protection

ARB Differential Breather Kits

ARB differential breather kits are important to vent air pressure in drivetrain assemblies, and they eliminate the shortcomings of your factory breathers—especially when driving through water crossings. ARB units are high-flow, zero backpressure, zero vacuum breather systems. Each features a high-flow air filter within a central manifold that will allow up to four drivetrain assemblies to be vented to one central location--ideally somewhere on the vehicle that will be above the water level at all times. ARB differential breather kits are intended to replace your factory breathers and contain enough fittings and tubing to connect at least two drivetrain assemblies. Additional features and benefits include: * Axle breather manifold is machined from billet aluminum and anodized, making it lightweight and resistant to the elements * The manifolds have four axle breather ports, allowing for 1-4 breather lines to be connected * Very compact design, allowing them to be installed in virtually any location * The kits come with self-tapping screws, but the manifold mounting holes are large enough to allow mounting using an M6 (1/4 in.) bolt or stud, which is the common size in most vehicle engine bays * The air filters are the ARB compressor air filters, which are splash-resistant with washable high-flow sintered bronze filter cartridges * 8mm polyethylene tubing is flexible, oil-resistant, water-resistant, and heat-resistant * 8mm tubing has been selected over the standard 6mm tubing to improve the airflow and reduce the chance of oil blockages in long breather lines * 8mm push-in fittings make installation simple and fast * Kits include anodized aluminum manifold with 5 ports (breather lines and air filter) and 2 mounting holes, air filter assembly, fittings, plugs, polyethylene tubing, screws, and cable ties
