Inner Bushing for Spring Pre-loaders

The inner bushing for spring pre-loaders from Allstar Performance is a precision component designed for racers and performance mechanics who demand tunable suspension geometry. This small but critical part manages the pre-load characteristics of coil-over and spring systems, allowing fine-tuned adjustment of vehicle ride height and spring compression without replacing entire assemblies. Whether you're dialing in a street rod, circle track racer, or road course competitor, this bushing isolates the spring and reduces friction at the pre-loader interface.

Manufactured from PTFE (polytetrafluoroethylene)—commonly known as Teflon—this inner bushing for spring pre-loaders delivers low-friction operation and superior wear resistance compared to rubber or steel alternatives. PTFE's self-lubricating properties minimize binding and allow smoother spring articulation, which translates to more consistent suspension response and easier height adjustments during setup. The white composite material resists degradation from heat cycles, oil exposure, and UV damage, extending service life across multiple seasons of competition or heavy modification work. At just 0.02 lbs, the bushing is engineered for 2.5-inch spring diameter applications, fitting seamlessly into OEM and aftermarket coil-over architectures.

Serious builders and suspension tuners rely on Allstar Performance inner bushings when replacing worn pre-loaders or upgrading existing systems. Installation is straightforward—remove the old bushing and press or slide the new PTFE component onto the spring perch—making it an ideal upgrade during suspension refresh or rebuild cycles. Compatible with any coil-over or spring pre-loader assembly rated for 2.5-inch springs, this bushing is sold individually, so verify your application requires a single replacement or purchase multiple units for full front-and-rear suspension work. Quality maintenance of pre-loader components ensures repeatable height settings and optimal handling balance lap after lap.
