TRZ Motorsports Under Axle Anti Roll Bar - Billet Arms (1979 - 2004 Ford Mustang) - MUS-203-3-UHM
Under-Axle Anti-Roll Bar with Billet Arms for 1979 - 2004 Mustang
The TRZ Motorsports Under Axle Anti Roll Bar is engineered for Mustang owners who need maximum launch stability, superior exhaust clearance, and rock-solid rear suspension control. Designed specifically for 1979 - 2004 Ford Mustang chassis, this anti-roll bar eliminates body roll and keeps the car planted and tracking straight during high-power launches.
The system uses strong 1-5/8" diameter chrome-moly tubing paired with ultra-rigid CNC-machined one-piece billet ARB arms measuring 5" from tube center to rod-end center. The under-axle design provides additional exhaust clearance, making it an excellent choice for street/strip cars running larger exhaust systems. Installation requires welding the ARB under the rear differential, with the provided tabs designed to weld directly to the rear frame rail. Overall end-to-end width is approximately 34.5".
