Description
Looking to give your 1979-2004 Mustang, whether it's a classic Fox Body or an SN95, a performance upgrade? QA1's Boxed Trailing Arms (Lower Control Arms) are exactly what you need. These trailing arms eliminate the flex and bind commonly found in stamped steel arms, delivering significant improvements in handling and stability to your Mustang.
BUILT TO LAST
Our trailing arms are constructed from larger rectangular tubing, providing the strength needed to handle any driving conditions. They feature fully capped radius ends, keeping dirt and debris out so you can enjoy worry-free cruising. The black powder coat finish not only adds durability but also delivers a clean, factory-like appearance that complements your Mustang's style.
IMPROVED HANDLING FOR EVERY DRIVE
Whether you're racing down the strip, cruising the streets, or taking on sharp corners, these trailing arms are designed to minimize suspension deflection. This results in a sharper, more responsive ride with reduced wheel hop. Plus, with reinforced sway bar mounting holes, you can easily retain your factory-style sway bar, making these arms far stronger than the old stamped steel versions that tend to flex under pressure.
A QUIET, COMFORTABLE RIDE
We understand that performance shouldn't come at the cost of comfort. That's why our boxed control arms come pre-assembled with greaseable polyurethane bushings. These bushings are engineered to reduce noise and vibration, ensuring a smooth and quiet ride every time you hit the road.
