QA1 offers upper and lower rear trailing arms for Ford and GM applications in boxed, tubular, and heavy-duty adjustable options. All upper tubular and lower boxed trailing arms use polyurethane bushings on both ends, while upper adjustable and lower tubular trailing arms use a spherical ball or rod end assembly on the chassis end to eliminate bushing bind, allowing the suspension to move smoother for better control. They are powdercoated or zinc plated and anodized for a long-lasting finish. Keep your tires planted firmly on the ground for improved traction and a more predictable, better handling car with a set of QA1 rear trailing arms. Features may include: * Boxed trailing arms are constructed from 0.120 in. wall cold rolled steel tubing for maximum strength and flex elimination. * Tubular trailing arms are constructed from 1 1/4 in. diameter, 0.120 in. wall steel tubing which offers increased strength over other designs, but also have the added advantage of lighter weight. * Boxed and tubular styles feature fluted, greasable polyurethane bushings, which are superior to the stock rubber bushings. * Heavy-duty adjustable trailing arms allow easy rear suspension adjustments for optimum handling and traction. Simply loosen the jam nuts and adjust the pinion angle without removing the arms from the vehicle. They replace soft OE differential bushings with polyurethane differential bushings, and they use a spherical ball or rod end assembly with UHMW polyethylene bushings on the chassis end * Adjustable styles are available in aluminum and steel options

The 1967-69 F-body was designed in an era when high performance driving and modern tire technology weren't as prevalent. Their unibody chassis, while innovative at the time, can flex and twist under stress, particularly when cornering aggressively or accelerating hard. QA1's bolt-on subframe connectors offer a simple and effective solution to this common issue. They tackle the flex issue by increasing frame rigidity, leading to a significant improvement in handling performance—especially during cornering, acceleration, and braking. The tubular design connects the front Camaro/Firebird subframe to the rear subframe, providing additional structural support and stiffness to the chassis. Additional details: * Included solid body mounts and hardware further reduce chassis flex. Their aluminum construction offers a noise-free alternative to polyurethane. * Thoughtful design: The QA1 subframe connector contours to follow the body lines for a factory-like look without sacrificing ground clearance. * Easy bolt-in installation makes the upgrade hassle-free. * Fitment notes: Does not fit convertibles.
