{"product_id":"qa1-upper-adjustable-trailing-arms-qap5247","title":"QA1 Upper Adjustable Trailing Arms | 1973-1988 GM G-Body \u0026 A-Body | 5247","description":"\u003cp\u003eThe QA1 5247 upper adjustable trailing arms allow easy rear suspension adjustment for 1973-1988 GM G-body and 1973-1977 A-body cars. The pinion angle is set by loosening the jam nuts and turning the arm without removing it from the vehicle. They replace the soft OE differential bushings with polyurethane and use a spherical ball or rod end with UHMW polyethylene bushings on the chassis end to let the suspension move freely and eliminate bushing bind, keeping the tires planted for better traction and more predictable handling. The adjustable arms are zinc plated and anodized and are sold in pairs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: upper adjustable trailing arms, sold in
