Toyota 4Runner / FJ Cruiser Polyurethane Billet Aluminum Rear Suspension Bump Stops 30mm Extended 2003 - 2024
Factory bump stops on lifted Toyota 4Runner and FJ Cruiser builds are notorious for insufficient travel, causing shock absorbers, control arm bushings, and stabilizer bar bushings to absorb repeated hard impacts — leading to clunking noises, accelerated wear, and costly repairs. These high-performance rear suspension bump stops are purpose-built for lifted and long-travel suspension setups, combining a high weather-resistance polyurethane cushion with an aircraft-grade billet aluminum base molded into a single unified structure. The 30mm extended design is compatible with vehicles lifted up to 1.5 inches, providing meaningful additional travel to protect critical suspension components on rough terrain and off-road use.
Features:
- High weather-resistance polyurethane cushion with excellent deformation and fracture resistance – performs reliably in extreme temperatures and harsh terrain conditions
- Aircraft-grade billet aluminum base provides structural strength and rigidity under heavy compression loads
- Molded-in-one-piece construction – aluminum base and polyurethane cushion formed as a single unit for maximum structural integrity and split-damage resistance
- 30mm extended design – compatible with vehicles lifted up to 1.5 inches and fitted with long-travel shock absorbers
- Direct replacement for OEM part number 48306-60180 – secures in the original location with no modifications required
- Anodized aluminum surface for full rust and corrosion resistance
