Kelltrac Rear Spring Spacer Kit Adjustable (2005 - 2014 Mustang) KTI-RSS05

Adjustable Rear Spring Spacer Kit – Fine-Tune Ride Height & Clearance

This rear spring spacer kit is a simple, effective solution for dialing in your ride height—perfect for drag racing setups or anyone looking to fine-tune stance, alignment, and tire clearance. The spacers install between the rear axle and coil spring, allowing height adjustments from approximately 1/8" to 1/2" depending on configuration.

Included in the kit is a stock-style rubber isolator made with higher-durometer material for better durability, and a pair of 1/4" nylon-carbon spring spacers designed to stack easily based on your setup needs.

Ideal For:
Enthusiasts running soft, lowered drag springs who need extra rear lift for tire clearance or improved alignment without sacrificing ride quality.

Adjustment Options:

1. Use our isolator in place of the stock one – adds ~0.125"

2. Stack our spacer on top of your OE isolator – adds ~0.250"

3. Replace OE isolator with ours, then relocate OE isolator above the cone – adds ~0.300"

4. Use our isolator + spacer in place of OE isolator – adds ~0.375"

5. Add our isolator + spacer without removing existing OE components – adds ~0.500"
