Product Description

The Bilstein 24-186599 B6 Rear Shock Absorber is engineered as a direct replacement for the rear suspension of 2002-2014 Class A motorhomes built on the Roadmaster R4R and RR4R chassis, including Monaco Ambassador, Cayman, Knight, Neptune, and Holiday Rambler Ambassador models. Built with Bilstein's Heavy Duty monotube design and velocity-sensitive piston, this shock delivers improved damping control and stability over worn OEM units, especially under load or heavy-use conditions.

Featuring a high-pressure nitrogen charge and durable yellow finish, the B6 rear shock maintains consistent performance across varied road surfaces while resisting corrosion and fade. Its rear-specific tuning enhances ride comfort and handling balance without requiring suspension modifications. Designed for reliable day-to-day use on large motorhomes, this shock absorber restores confidence to rear suspension dynamics and ensures a smoother, more controlled ride experience for drivers and passengers alike.
