KellTrac Double Adjustable Rear Coilover Kit – Stock Location (Street)
1979–2004 Ford Mustang | Fox / SN95 / New Edge
Street-Focused Performance with Serious Adjustability
The KellTrac Double Adjustable Rear Coilover Kit is engineered for Mustang enthusiasts seeking improved stance, superior performance, and real-world street comfort in a stock shock location. Designed specifically for 1979–2004 Fox, SN95, and New Edge Mustangs, this Street/Strip rear coilover system was developed over more than a year of testing to deliver increased shock travel, greater adjustment range, and improved rear wheel rate options while reducing weight by an average of 15 lbs.
Whether your Mustang is a daily driver, weekend cruiser, autocross car, road race build, street car, no-prep racer, or drag setup, this KellTrac system provides immediate improvements in handling, traction, ride quality, and appearance. From the moment it’s installed, you’ll feel the difference in control, responsiveness, and overall confidence.
Premium Components & Viking Shock Technology
At the heart of this kit are legendary double adjustable Viking Performance Warrior coilover shocks, custom-valved specifically for KellTrac to deliver the ideal balance of street comfort and performance capability. Adjustable compression and rebound valving allow precise tuning for varying surface conditions and driving styles. Custom 2.50-inch Landrum Performance coilover springs are spec’d per application to ensure proper wheel rates and consistent performance.
CNC-machined billet upper mounts, durable lower offset shock mounts, and extreme-strength mounting hardware provide rigidity and reliability while remaining lightweight enough for competition use. High-durometer polyurethane bumpstops come pre-installed to protect the shocks and maintain controlled suspension travel.
Designed for Street, Strip, Track & Autocross
This system was designed and tested exclusively for street, strip, track, and autocross use, delivering a wide tuning window without sacrificing drivability. The stock-location design simplifies installation while maximizing performance gains. With adjustable ride height and valving, users can fine-tune stance, traction, and handling to match their specific setup and driving goals.
