4-Link Kit

The Competition Engineering 4-Link Kit (model C2017) is a weld-on suspension control system designed for vehicles requiring enhanced axle location and stability during acceleration, braking, and cornering. This kit is ideal for fabricators and performance enthusiasts looking to design custom rear suspensions or upgrade existing systems.

This standard series 4-link kit comes complete with all necessary brackets and hardware, providing a bolt-together solution for custom chassis and performance vehicle builds where precise rear-end geometry is critical. The kit accommodates 3-inch axle tubes and is constructed from steel and chromoly materials in a natural finish, ensuring the structural integrity required to manage lateral and fore-aft forces under hard acceleration and deceleration.

Four-link suspension systems utilize four control arms (two upper, two lower) to locate the rear axle while allowing vertical suspension movement, resulting in reduced wheel hop and improved traction compared to older leaf-spring or simple two-link designs. The weld-on configuration allows for precise bracket placement and geometry tuning, making this kit suitable for drag racing, road racing, street performance, and off-road applications where axle control is essential.
