KellTrac IRS Subframe to Chassis Stud Kit (KTI-HWK15RS) - 2015–2026 Ford Mustang
The KellTrac IRS Subframe to Chassis Stud Kit is a simple but critical upgrade for 2015–2026 Mustangs, designed to eliminate the headaches caused by factory subframe mounting bolts. Whether you’re installing suspension components, adjusting alignment, or frequently dropping the IRS for race prep, this stud conversion kit provides added strength, reliability, and ease of service.
By replacing the OE bolts with high-strength studs, this kit allows precise adjustment of subframe height and angle without risking thread damage in the chassis. It also prevents common issues like cross-threading—especially at the notoriously problematic front driver-side mount—making it an essential upgrade for both street performance builds and dedicated race cars.
Designed with real-world Mustang service and racing experience in mind, the KellTrac stud kit ensures your IRS subframe remains securely supported even when lowered significantly, reducing downtime and protecting critical mounting points.
