TRZ Motorsports Adjustable Lower Control Arm Mounts - Unwelded Doublers (1977 - 1996 B-Body) - 209-32
Adjustable Lower Control Arm Mounts for GM B-Body Rear Suspension
The TRZ Motorsports Adjustable Lower Control Arm Mounts (209-32) are engineered for racers and suspension tuners looking to fine-tune rear geometry on GM B-Body vehicles. With six selectable pickup points, these mounts allow precise adjustment of anti-squat, instant center, and traction characteristics. Each kit includes 1/2-inch hardware and precision-machined spacers designed specifically for 3/4-inch rod-end control arms, ensuring tight and reliable fitment under demanding conditions.
These brackets must be paired with double rod-end lower control arms and are not compatible with bushing-style arms. TRZ recommends a 5-degree rearward mounting angle from the differential cover surface. Optional doublers - available unwelded or welded - add additional reinforcement. When using doublers, the customer must weld the final gusset to the axle tube.
Mustang users should note these brackets cannot be used alongside a spring-on-arm style suspension; TRZ's MUS-200R or equivalent rod-end arm is required. TRZ also offers platform-specific arms for A-Body, G-Body, and F-Body vehicles, plus 209-24 stock location shock mounts and No Prep extended LCA brackets for more aggressive geometry changes.

Frequently Asked Questions
Do these work with OEM-style bushing lower control arms?
No. These mounts are designed exclusively for double rod-end LCAs. Bushing-style arms will not fit.
Are doublers mandatory for installation?
No, but they are recommended for added housing reinforcement. When using doublers, the final gusset must be welded to the axle tube by the installer.
