An integrated composite torsion cartridge is molded to size and configuration. The integrated composite torsion cartridge includes a torquearm, bearing surface, shoulder, torsion bar cluster, and mating axle tube countertorque hub in a homogeneous subassembly. A spindle being steel for example, can be secured to torquearm with a typical fastening technique. An extruded length bearing block can be cut to a finished size and mounting holes installed. Using a pair of bearing blocks, one above and one below, the bearing blocks intimately fit about an integrated torsion subassembly bearing area and both bearing block mating edges engaged to maintain location. If desired, the mating bearing block edges can be bonded together for greater retention.
