Product images may differ from actual product appearance.

Competition Engineering Rear Frame Rails replace stock rear rails in subframe-equipped cars. Stamped from sheet metal, stock rear rails were never intended to handle more than stock horsepower levels. When higher power is achieved, stock rear frames bend and twist under the strain, absorbing power that could be used to make the car accelerate quicker. Each rail is mandrel-bent on computer-controlled machines to eliminate the kinks and wrinkles often found in other frame rails. The finest 2" x 3" x .083" wall mild steel tubing is used to guarantee unequaled strength that's lighter than stock. Welding required for installation.

Competition Engineering Weld-In Subframe Connectors are engineered to provide a solid connection between the front and rear subframes on unibody vehicles. Similar to their bolt-on counterparts, these connectors offer a solid foundation for traction control crossmembers and eliminate twisting in the chassis.

Each Kit Includes:
  • Competition Engineering Rear Frame Rails (2" x 3" x .083" wall mild steel tubing)
  • Competition Engineering Weld-In Subframe Connectors (2" x 2" x .083" wall mild steel tubing)
