Spidertrax Off-Road's all-new 1480 40 spline front axle stubs are a reinvention of their already proven 35 spline stub shafts. Manufactured from billet 300M aerospace material with an integrated positive locking design—all while achieving 50 degrees of steering—they're the next best thing in stub shaft technology… and the last stub shafts you'll ever need. These 1480 40 spline stub shafts are designed to work with 60 style U-joints and Spidertrax 40 spline Ultimate Unit Bearings. * Aerospace Quality: Spidertrax follows the strictest AMS Aerospace standards for their heat treatment, complete with double tempering, snap tempering, and cryogenic treatment procedures. Parts are sampled to ensure proper grain structure is achieved up to 0.0003 in. from the surface; that's a depth 1/10 the thickness of a human hair! In summary, you're getting the best material and the best heat treatment on the market. * Locked: Turning 40 degrees is impressive, but Spidertrax axle shafts can turn 50 degrees. Engineers achieved this by positively locking the shaft to the Ultimate Unit Bearing with a billet aluminum cap and cap screw. Keeping that stub shaft tightly secured not only helps with driveline vibration, but helps with overall strength of shaft and U-joint. * 40 Splined: Each stub shaft is 40 splined—a size that makes perfect sense, especially when running properly paired inner axle shafts. When sized with the same shaft diameter as inner shafts, stub shafts end up taking the full punishment in your front-end. The stub shaft should be "stronger" than an inner axle because unlike an inner axle, stub shafts have little room to twist, making them more prone to failure. An added bonus: with many drivers running 40 splined rear Ultimate Unit Bearings, having the same unit bearing up front makes for better serviceability and part simplicity.

Trail-Gear Rock Assault front axle housings give you clearance to go where you want and the muscle to do it! Their strength comes from heavy-duty, press-formed, 1/4 in. plate steel center sections; 1/2 in. plate steel differential mounting surfaces; 5/16 in. thick 1020 DOM axle tubes; and forged 1035 steel knuckle balls. Trail-Gear's knuckle balls are stronger than stock, so there are no worries of them becoming closed or bent. And, the thicker differential mounting surface ensures that the studs cannot pull out, even under heavy loads. Trail-Gear's design—offset tubes and shaved center section—provides you with added clearance to climb the high country. Plus, since housings are precision-aligned with computer imaging, you can rest assured they're 100 percent straight and true. You have a choice of bare tubes, or with spring perches installed—or 3-link ready with a panhard bracket included. You're equipped to attack any terrain with Trail-Gear Rock Assault front axle housings.

Spicer Drivetrain Products front axle shafts feature an increased U-joint size that provides 25 percent higher yield strength than original U-joints. They offer unparalleled strength and longer life—the outer stub is re-engineered for added strength; improved snap ring retention reduces shock load failures; and material has been removed from the body and added to the yoke ears (to equalize deflection through the yoke and reduce bearing cap spinning). The axles are made from durable steel, with a micro-alloy improving their strength and a statistically controlled heat treatment ensuring proper hardness.

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

Years after releasing their successful Rock Assault 9 axle housing, Trail-Gear decided to add a Toyota 8 in. version to the Rock Assault lineup. This housing is built to the same specifications as the Rock Assault 9 axles; however, they're built to accept the popular Toyota 8 in. differential. These housings have been tested in W.E. Rock, CalRocs, and King of the Hammers—so you know they'll stand up to the toughest terrain on earth. Trail-Gear started with a 1/4 in. thick formed shell for the center section made from A36 steel. This is a high-strength, low alloy, structural steel plate with a minimum yield strength of 36,000 psi. All of this is attached to an equally strong 1/2 in. thick faceplate for anchoring the DOM axle tubes. The axle tubes are secured by the industry's first 3-Point Attachment System, giving the tubes superior support and engagement into the center section. Trail-Gear also faces the center section to ensure your differential mounts flush against the axle housing to prevent any leaks. Rock Assault Fabricated 8 Housings are offered with 3.5 in. O.D. axle tubes with your choice of 1/4 in. or 3/8 in. wall thickness. NOTE: The housing is shipped with no ends. Housing ends must be sourced and installed to complete axle. Portal style ends are commonly used for this application.
