Overview

The Competition Engineering C1626 is a Rear 4-Link Frame Kit designed for custom chassis fabrication. This comprehensive kit provides the structural foundation for high-performance drag racing and custom vehicle builds, allowing for a 4-link rear suspension setup that offers superior traction and handling.

The kit features 2x3 inch box tubing frame rails with a 26-inch width and a 2x3 inch dropped crossmember (60 inches wide with a 3.5-inch drop). Components are constructed from durable materials, including 3/4-inch O.D. DOM steel for the diagonal link, which also utilizes 1/2-inch spherical rod ends for precise movement.

Installation requires extensive custom fabrication, including welding and cutting to fit the specific vehicle chassis. The kit includes the C2017 4-link kit, C2051 3-way adjustable drag shocks, shock crossmembers, upper/lower shock mounts, and a driveshaft safety loop. It is engineered for vehicles weighing between 1,900 and 2,900 lbs.

This is a universal-fit component intended for custom racing applications. It is not designed as a direct-fit replacement for any specific factory vehicle chassis. Professional welding and fabrication skills are required for safe installation and performance.
