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.

The RevMax custom coated transmission pump plates are a must-have part on any 68RFE rebuild. The factory plate is typically found to have excessive grooving in it and should always be replaced during an overhaul. These custom laser-cut steel alloy plates are heat-treated to insure flatness and hardness and are then finished with RevMax's proprietary friction reducing and self-lubricating electrostatically applied coating. This special coating reduces pump wear from the pump gears by decreasing surface friction and increasing lubrication during dry startups. These plates will work with all factory pumps regardless of manufacture date and with aftermarket pumps.

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.
