Kelltrac IRS Bushing Upgrade Kit Level 1 (2024-2025 Mustang GT & Dark Horse) KTI-BUK24L1

This Level 1 KellTrac S650 Mustang IRS Bushing Upgrade Kit for the S650 Mustang positively locates the rear IRS Subframe AND the rear lower control arms within the chassis. By filling the voids within the factory bushings on the Subframe Mounts and putting positive pressure on the factory bushing stops, the PosiLoc kit eliminates the deflection found within the stock assembly that leads to poor performance in all scenarios. By completely removing the sloppy rubber in the factory front Lower Control Arm bushing, the Spherical Bearing kit positively and precisely locate the rear axle knuckle assemblies within the chassis. These Lower Control Arm Bearings are made from only the best materials. The factory rubber bushings, or even aftermarket polyurethane bushings deflect under heavy loads - these bearings eliminate that deflection that leads to poor performance in all scenarios. With our Level 1 kit we provide front centering sleeves to complete the squareness of the IRS Subframe when mounting to the vehicle. Whether you are a spiritedly street cruising, drag racing, road racing or auto-crossing this Level 1 KellTrac Bushing Upgrade Kit will significantly improve the performance and feel of your S650 Mustang.
