The Full Tilt Boogie Racing FT 5001 Complete IRS Bushing Kit is engineered to significantly enhance the durability and performance of your 1999-2004 Mustang Cobra's independent rear suspension (IRS). This comprehensive kit aims to eliminate common issues such as wheel hop and potential breakage that can plague the stock Ford IRS setup, ensuring it performs optimally under demanding conditions. The kit components are crafted from robust materials for longevity and performance. It 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, the kit provides FT 1200 Aluminum Front Diff Supports with shimming washers to precisely set pinion angle, and an FT 1401 Delrin Isolated Rear Diff Lowering Mount. Additionally, it features FT 1500 UHMW IRS Subframe Supports for added stability, along with FT 1600 Grade 8 bolts and nylock nuts, and an FT 1700 Combination UCA and LCA bushing grease fitting kit. This kit is specifically designed for the 99-04 Mustang Cobra IRS only. It is an ideal upgrade for owners looking to maximize the efficiency and resilience of their IRS system, especially when driving the vehicle at its limits.
