MaxTrac Suspension has a new lowering kit that drops F-150s three inches in the front and five inches in the rear. The system is designed for easy installation — no C-notch or gas-tank removal required. Up front, shorter MaxTrac coils replace the stock springs. The rear uses a flip kit and new shackles with the stock leafsprings. Replacement rear gas-charged twin-tube shocks are included, as are U-bolts and all necessary hardware. No cutting or welding is required. MaxTrac also offers other lowering kits and components to drop F-150s anywhere from one inch to six inches. All MaxTrac products are backed by a limited lifetime warranty.
