QA1 Adds Rear Trailing Arms to 73-77 GM A-Body Suspension Offerings
QA1 is excited to announce the addition of rear upper and lower trailing arms for 1973-1977 GM A-Body vehicles, including Chevelles, Monte Carlos, Cutlasses and Regals. These American-made trailing arms allow you to get better handling by keeping the tires planted firmly on the ground for improved traction and a more predictable, more stable car.
Upper trailing arms are available in either tubular or adjustable styles. The tubular arms offer increased strength, while the adjustable arms allow easy and precise pinion angle adjustments without having to remove the arms from the vehicle. Lower trailing arms are available in a sturdy boxed style for maximum strength and flex elimination and include mounting points for an OE style sway bar.
The upper tubular and lower boxed trailing arms use polyurethane bushings on both ends, while the upper adjustable arms use a spherical ball or rod end assembly with UHMW polyethylene bushings on the chassis end to eliminate bushing bind. For a long-lasting finish, tubular and boxed trailing arms are powder-coated gloss black, while the adjustable arms are zinc plated and anodized.
These rear upper and lower trailing arms complement stock or QA1 front GM street control arms and GM race control arms, as well as front Pro Coil Systems and rear Pro Coil Systems for these vehicles, and are manufactured in QA1’s Lakeville, Minnesota facility.
