Fortin Racing, Inc. has applied over 40 years of off-road racing drive train experience to the Can-Am X3 rear driveline. The mission was to improve the strength and reliability of the rear hub, upright, bearings, CV’s, axles and brakes. With the increased loads from larger diameter tires and wheels, heavier vehicle weights, and the demands of endurance off-road racing, a complete redesign was required. Starting with the upright or bearing carrier, the stock cast aluminum part was redesigned utilizing aerospace quality 7075 billet aluminum. Keeping all the stock link and trailing arm pivots in place, the stock bushings have been replaced with precision spherical ball bearings. The rear wheel bearings have been replaced with large 4.3” taper roller bearings. The rear hub hat has been made with light 6061-T6 billet aluminum to keep rotating weight to a minimum while keeping the stock 12mm 4 bolt wheel stud pattern. For improved braking power, larger 11” diameter rotors and exclusive Fortin 4 piston radial mount race calipers by Stop Tech have been incorporated. Piston bore diameters have been designed to be used with the stock master cylinder. The stock metric brake line banjo fitting bolts directly on the caliper. Applying years of CV joint manufacturing experience, 300m and aerospace alloys have been used in an all-new non-plunging high angle CV joint. The CV’s are bolted to the inner and outer stub axles flanges eliminating the use of wire spring clips and making the assembly more serviceable. The high angle CV boots are fixed to removable flanges as well. The 300m axle shafts are custom made to the required length for the specific width of the car. The kit comes complete with inner stub axles that are through-bolted into the rear differential.
