Sometimes it’s best to take a step back, look at an already proven design with an open minded attitude, and start from scratch. This may sound strange, why change something if it’s already working? It’s the heart of engineering, with Ultra4 growing as fast as it is staying on top of the curve is the best insurance you can have for securing that next podium finish.
Say hello to the all new 40 spline Pro Series Stub Shaft, a reinvention of the already proven Ultimate Stub Shaft. Manufactured out of billet 300M aerospace material, with an integrated positive locking design, all while achieving 50° of steering, it’s the next best thing in stub shaft technology… and the last stub shaft you will ever need.
Pro Series Stub Shafts are designed to work with 60 style u-joints and Spidertrax 40 Spline Ultimate Unit Bearings.
