~(15 lbs. 15X10X8)~ Spidertrax 40 Splined 300M Billet Series 30 Outer Stub Shafts (Pair)

The Spidertrax 30 Series 40 Splined 300M Billet IFS Stub Shafts are high-performance axle shafts designed for Independent Front Suspension (IFS) drivetrains, particularly for demanding applications like Ultra4 racing. Sold as a pair with retaining nuts, they are engineered to integrate with Spidertrax 40 Splined Ultimate Unit Bearings and the race-proven GKN 30 Series CV design. This combination allows for significant misalignment, crucial for sharp steering and extended suspension travel in off-road conditions.
Constructed from military-grade 300M billet steel, these shafts undergo a rigorous manufacturing process including multiple post-heat treatment CNC operations to achieve tight tolerances. They are heat-treated to aerospace standards, featuring double tempering and cryogenic treatment, ensuring superior quality and durability for specialized builds.
