The Eibach AK31-82-071-BMP Progressive Bump Stop Kit is designed to improve rear suspension travel, control, and impact management on select Toyota 4Runner applications. Developed for off-road use, this kit helps provide a more controlled suspension response when the rear axle reaches its compression limit, supporting improved performance over uneven terrain and during demanding driving conditions.

This rear bump stop kit includes progressive-rate polyurethane bump stops, a billet aluminum relocation block, and the required installation hardware. The progressive polyurethane construction helps provide increasing resistance as suspension compression progresses, while the relocation components help position the bump stops for improved suspension functionality. The kit is sold as a pair for the rear axle and is engineered as a direct-fit suspension accessory for compatible vehicles.

Designed and manufactured by Eibach, the AK31-82-071-BMP provides a practical upgrade for drivers seeking improved rear suspension control without replacing the complete spring or shock system. It fits select 2010, 2011, 2013, and 2015 Toyota 4Runner models; verify the vehicle’s exact year, drivetrain, and suspension configuration before ordering. Professional installation is recommended to ensure correct positioning and secure installation of the relocation block and hardware.
