GM Triangulated Rear 4-Link Suspension Kit
The GM triangulated 4-link rear suspension design has been a trusted choice for decades, known for eliminating the need for a Panhard bar while delivering superior stability and control. This kit is engineered to accommodate a variety of frame widths, with formed upper frame brackets that may be trimmed as needed to ensure a precise fit.
Key Features and Specifications:
- Heavy-Duty Bars: The upper and lower link bars are fabricated from 1" heavy-wall seamless tubing for maximum strength. Each bar is precision-tapped at one end with 3/4-16 threads and notched at the other end to house the urethane bushing tube, ensuring reliable articulation. Upper bars measure approximately 18" center-to-center, while lower bars span 25" center-to-center.
- Shock Mounting Options: The axle brackets offer three mounting positions for shock absorbers, allowing for flexible positioning to suit your setup.
- Precision-Matched Bracketry: All brackets are precisely matched to the outer diameter of the 1-3/4" wide Energy Suspension urethane bushings, providing optimal vibration dampening and a clean, professional appearance.
Premium Material Construction:
- Axle Brackets and Tabs: Constructed from 3/16" pickled and oiled mild steel for enhanced durability and corrosion resistance, the axle brackets and upper axle tabs are designed for demanding applications.
- Upper Frame Brackets: Made from CNC-formed 10-gauge pickled and oiled mild steel, these brackets offer structural integrity and ease of adjustment. Lower frame brackets are 3/16" thick P&O steel, and the formed bar brackets feature 10-gauge P&O steel.
Complete Kit Components:
- #318500 triangulated rear four link kit (welded or ready-to-weld) with 1-3/4″ wide urethane bushings from Energy Suspension and 3/4-16 threaded adjusters.
- #21870 axle brackets for air springs
- #474219 frame brackets for upper air spring mount
- #WS154460 crossmember kit for upper shock mount.
Welded vs. Ready-to-Weld Options:

- Welded Kit: Expertly TIG welded in-house, this option provides a complete, ready-to-install setup.
Additional Information: Assembly and installation instructions are included to guide you through a smooth setup process.
