KellTrac Triple Adjustable Rear Coilover Kit, Race Series (KTI-RCO15TA-R) - 2015–2026 Ford Mustang
The KellTrac Triple Adjustable Race Series Rear Coilover Kit is engineered for extreme-performance Mustang builds where precision, control, and durability are non-negotiable. Highly recommended for 1,000+ RWHP drag race applications, this system delivers unmatched adjustability and tuning range to keep high-powered S550 and S650 Mustangs planted and consistent under the most demanding conditions.
Developed through more than a year of intensive testing, this triple adjustable setup provides independent control over multiple shock characteristics, allowing experienced tuners to dial in rear suspension behavior for virtually any surface or racing environment. Built around legendary Viking Crusader triple adjustable shocks and custom Landrum Performance springs, this kit offers superior shock control, improved traction, and repeatable results—while still reducing rear suspension weight by an average of 20 pounds.
Assembled in-house and ready for installation, the KellTrac Race Series Triple Adjustable Rear Coilover Kit is designed for racers who want maximum control over their suspension setup and the ability to extract every last bit of performance from their Mustang.
