The radius arms are welded to the Traction Beam housings for strength and simplicity. Check out the bumpstop pad built into the arm-to-beam gusset. The driver-side beam was extensively gusseted and plated. Three-inch-diameter, fourteen-inch-stroke King coilovers net 16 inches of front travel with fully functioning four-wheel drive. To maintain the suspension, the front end gets new bushings and Heims about once a year, and the rear end gets the same treatment twice a year. Since these suspensions endure thousands of miles of severe use, regular replacement intervals are the best way to ensure being able to drive home after each Baja prerun.
