Camburg uni-ball upper control arms will give you smother travel and greater strength. These arms incorporate the same huge 1.250" uni-balls and spacer design like Camburg's Long Travel kit. The 1.250" uniballs yield far more angle than the 1" uni-balls in their previous design. Also used in the new UCA design is all new spacers with the upper bolt recessed into the top spacer. This allows 1.250" more clearance from the old design allowing more compression wheel travel than before. For the hardware, Camburg went all out utilizing 12-point race hardware and heat treated stainless spacers. Also note the stainless clamps for your ABS lines on the arm. The design of these arms incorporates caster and camber correction needed when lifting the Toyota trucks as well as superior strength and more wheel travel. Energy Suspension urethane bushings are used to replace the stock rubber bushings that bind the upper arms and add stress to the upper A-Arm mounts.
