The truck has several pieces from STRC which include the drive hexes, front and rear hinge pin braces, idler pulleys, motor heart sink plate and the most impressive (IMO) is the quality of the shock bodies and upper spring perch. Makes adjusting the ride height easy with the large knurled threaded collars. I also have a set of STRC rear bearing blocks that are not installed yet that are also very high quality. The STRC stuff has better quality (fit/finish) than other aftermarket components I have used from other vendors in the past.
