TRZ Motorsports Adjustable Lower Control Arm Mounts - Welded Doublers (1977 - 1996 B-Body) - 209-33
Welded-Doubler Adjustable LCA Mounts for GM B-Body
The TRZ Motorsports Adjustable Lower Control Arm Mounts with Welded Doublers (209-33) are a premium solution for racers looking to fine-tune traction and rear suspension geometry on GM B-Body platforms. These brackets feature six pickup points that let you precisely adjust instant center, anti-squat, and rear bite characteristics for drag racing, street/strip, and no-prep applications.
This version includes factory-welded doublers for added strength and rigidity, eliminating fabrication time on your end. TRZ provides 1/2-inch hardware and precision-machined spacers designed specifically for 3/4-inch rod-end lower control arms, ensuring a tight, race-ready fitment. These mounts must be used with double rod-end LCAs and are not compatible with bushing-style rear arms.
TRZ recommends mounting the brackets at a 5-degree rearward angle relative to the differential cover surface. Mustang users should note these cannot be used with a spring mounted on the control arm; TRZ's MUS-200R or similar double-adjustable rod-end arm is required. TRZ also offers platform-specific rod-end LCAs for A-Body, G-Body, and F-Body platforms, along with 209-24 stock location shock mounts when needed.
