IRS Bushing Kit

The Full Tilt Boogie Racing FT 5001 Complete IRS Bushing Kit is engineered to significantly upgrade the rear suspension of your 1999-2004 Ford Mustang Cobra. This comprehensive kit replaces worn or degraded factory rubber bushings with high-performance Delrin components and other durable materials. The kit includes FT 1000 Delrin Upper Control Arm Bushings with hardcoated inner sleeves, and FT 1100 Delrin Lower Control Arm Bushings with hardcoated inner sleeves and shimming washers. For the differential, it provides FT 1200 Aluminum Front Differential Supports with shimming washers for precise pinion angle setting, and the FT 1401 Delrin Isolated Rear Differential Lowering Mount to optimize driveline angles. Additionally, the kit includes FT 1500 UHMW IRS Subframe Supports for improved stability and FT 1600 Front IRS Subframe Mounting Bolts. A key feature of this kit is the inclusion of the FT 1700 Combination UCA and LCA Bushing Grease Fitting Kit, which facilitates easier maintenance and ensures proper lubrication of the new bushings. These components work together to reduce unwanted flex and movement in the IRS system, leading to improved handling, better power delivery, and a more solid feel. This kit is specifically designed for the 1999-2004 Mustang Cobra models. While not explicitly stated as a requirement, the FT 5001 kit is often paired with the FT 1350M Ford Racing Reinforced IRS Rear Differential Cover for optimal performance and fitment, with a combo deal available.
