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. 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
