TRZ Motorsports No Prep Adjustable Lower Control Arm Mounts - Unwelded Doublers - 209-34
Unwelded No Prep Adjustable LCA Mounts for Custom Rear Suspension Builds
The TRZ Motorsports No Prep Adjustable Lower Control Arm Mounts (Part #209-34) are engineered for racers building custom rear suspensions who want maximum adjustability, strength, and flexibility. Designed specifically for double rod-end style lower control arms, these mounts feature dual hole sets with 13 total adjustment points, allowing precise control of anti-squat, instant center, and rear-end geometry.
These mounts fit a standard 3" axle tube, but can be modified to work with 3.25" or 3.5" tubes - making them compatible with popular Ford 8.8 and GM 10-bolt housings. TRZ includes machined spacers designed for 3/4" rod-ends, 1/2" bolts, four doublers, and four gussets for added strength. The axle tube location can also be adjusted during installation to suit your specific setup.
These mounts are supplied unwelded, giving builders full flexibility. The back plate must be installed at a 10° angle from the faceplate/rear cover for proper geometry. TRZ also offers pre-welded versions for an additional charge.
Several chassis-specific TRZ double-adjustable lower control arms are available, including options for 79 - 04 Mustang, 2005 - 2014 S197 Mustang, A-body, G-body, and F-body applications.
Important: These brackets cannot be used with bushing-style LCAs, stock shock mount locations, or any spring that mounts on the control arm. Unmodified, they will hang lower than a beadlock ring. For a higher-clearance setup, use TRZ's 6-Hole Adjustable Lower Control Arm Brackets.
