QA1 5221 Lower Boxed Trailing Arms for Select 1979-2004 Ford Mustang & Mercury Capri

Fits select 1979-2004 Ford Mustang and 1979-1986 Mercury Capri models. These QA1 Lower Boxed Trailing Arms are engineered to eliminate the suspension flex and bushing bind common with factory stamped-steel components. By replacing soft OE rubber bushings with high-durometer polyurethane, these arms keep the rear axle properly aligned and the tires planted for improved traction and more predictable handling during hard acceleration and cornering.

Constructed from heavy-duty 0.120-inch wall cold-rolled steel tubing, these boxed arms provide maximum rigidity for high-torque applications. They feature a durable gloss black powder-coated finish for long-term corrosion resistance and include fluted, greasable polyurethane bushings that ensure smooth suspension articulation without the maintenance headaches of dry bushings.
