UMI Performance 1964-1972 GM A-Body Adjustable Lower Control arms, Off Set Bushings, CrMo - 4023OFCM-R
UMI P/N 4023OFCM features off-set aluminum bushings and smaller diameter tubing that place the control arm inward for additional clearance when running large tires. This type of set-up is also needed when running a mini-tub to achieve the most clearance as possible. The supplied aluminum step bushings place the control arm inward 3/8 of an inch further then our standard control arm version. These double adjustable control arms are designed for race applications and light duty street use. The spherical rod ends offer a solid foundation and work excellent as a solid bushing control arm while eliminating rear suspension bind. The double adjustment allows easy on car changes for wider tire clearance and to center aftermarket rear ends. These race application control arms are manufactured from 4130 CrMo steel and TIG welded for the utmost in strength. The premium Teflon lined rod ends attach to the control arms using in-house machined 4130 CrMo tube adaptors. UMI P/N 4023OFCM allows adjustments of 1” longer or 1” shorter and are supplied pre-set to factory length. These race style control arms are designed for aftermarket sway bars that do not attach to the control arms; control arms are supplied with no sway bar holes.
UMI Performance bump steer kits relocate the outer tie rod pivot point which results in decreased toe change during wheel travel. Standard kits include sleeves, rod ends, jam nuts and high quality, direct fit tapered studs. Race kits require drilling of the spindle and include heavy duty 5/8 bolts. Race kits are recommended for autocross and road race applications while standard kits are indicated for street/strip use.
