Spidertrax Off-Road Front Axle Stubs

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.
