GForce Outlaw Axle Shafts
High-horsepower and stock axles are fine if you're sitting in neutral and revving the engine, but foot-pounding acceleration requires Gforce Outlaw axle shafts. These direct bolt-in axles feature anti-wheel hop technology for smoother launches, powdercoating for corrosion resistance, and extremely strong CNC-machined one-piece outer and inner billet stubs. Their proprietary aerospace billet alloy shafts use large 31-spline axle bars and 31-spline severe-duty CV joints, enabling these IRS axles to support awe-inspiring performance! Outlaw CVs produce greater travel and operating angles than OE joints, helping to keep tires on the road instead of loitering in outer space. All axle assemblies are hand-built in the USA with premium materials. Order the model recommended for your application.

Advance Adapters NP231 Slip Yoke Eliminator Kits
The Jeep NP231 is one of the most popular transfer cases, but it creates an extremely short rear driveshaft. These fixed yoke kits from Advance Adapters add 3 to 4 in. to the rear driveline length on a YJ, and up to 6 in. on a TJ. This results in a better driveshaft angle, eliminated driveline vibrations, and a transfer case that's ideal for trail use.
