Adjustable Spring Spacer Steel

The Adjustable Spring Spacer Steel from AFCO Racing Products is a precision weld-on suspension component designed for racers and performance enthusiasts who demand tunable ride height and spring preload control. This universal spacer accommodates 5 to 5.5 inch coil springs, making it an essential upgrade for vehicles requiring field-adjustable spring characteristics without permanent frame modification. Whether you're dialing in a high-performance street machine or fine-tuning a track car, this adjustable spacer delivers the flexibility serious competitors need.

Manufactured from steel and finished with zinc plating for corrosion resistance, the Adjustable Spring Spacer Steel measures 8.55 x 3.3 x 9.75 inches and weighs 2.53 lbs—light enough to minimize unsprung mass while robust enough to handle sustained racing loads. The weld-on design ensures a permanent, load-bearing connection to your chassis, while the adjustable spacer stack allows you to modify spring preload and ride height without breaking welds or purchasing multiple fixed spacers. Zinc plating protects against rust and extends component lifespan in harsh racing environments.

This product is ideal for suspension builders, performance shops, and DIY tuners working on independent front or rear suspension systems. Installation requires welding to the vehicle chassis—a task best performed by experienced fabricators familiar with suspension geometry and safety protocols. The universal design works across multiple platforms, but spring diameter and vehicle weight must be verified before purchase to ensure proper fitment and suspension compliance.
