Key Features & Benefits

• Polyurethane Construction — Much stiffer and longer lasting than standard rubber, while still managing NVH (noise, vibration, harshness)

• Tight Tolerance Fit — Designed to match factory mounting points and minimize slop

• Enhanced Handling — Reduces deflection in high load situations, improving response and consistency

• Durable Design — Engineered for longevity under daily driving and performance use

• Warranty — Lifetime warranty on bushing materials

Technical Details & Specifications

• Position: Rear, lower‑outer control arm (hyme joint style)

• Outer Diameter (OD): ~40.2 mm for the hyme joint housing

• Kit Status: Available for preorder (lead time ~4‑6 weeks)

• Intended Use: Replacement or upgrade for vehicles with worn rear suspension bushings

Installation & Performance Notes

• A clean suspension environment and proper press tools are recommended

• Bushings should be installed without preload (i.e. suspension at static ride height)

• After installation, recheck torque specs and monitor for any signs of play

• Improves turn-in and rear-end stability, while helping reduce irregular tire wear

Fitment & Compatibility

This kit is suitable for various Ford, Toyota, and Subaru applications using hyme joint style control arms. Always verify fitment based on your vehicle’s model year, subframe, and control arm configuration.
