- The universal design can be used for most cars ranging from Pro Street to Drag Racing
- Narrows the rear chassis to accept extra-wide tires
- Increases chassis strength for quicker vehicle reaction times
- Requires the stock rear floor pan to be substantially modified or removed - The addition of a full roll cage is also required for proper installation
- Use Competition Engineering Drop Crossmember 247-3061 for a solid mounting point for suspension components
Unmatched Rear Chassis Strength
Competition Engineering Rear Frame Rails replace the stock rails in subframe-equipped cars, eliminating the chance of bending and twisting under higher horsepower strain. Each rail is mandrel-bent on a computer-controlled machine to remove kinks and wrinkles often found in other frame rails. Only the finest mild steel tubing is used to guarantee unequaled strength and weight savings. Please note that some welding is required for installation.
Well these frame rails work on my 99 Silverado
