Bilstein 19-22 Dodge Ram 1500 B8 8100 (Bypass) Rear Right Shock Absorber - 0-2in Lift 25-259018

If your Ram feels bouncy or uneven at the back, the Bilstein B8 8100 Rear Right Shock Absorber is made exactly for that kind of upgrade. It’s designed for 2019–2022 Dodge Ram 1500 trucks and works great on setups with 0–2 inches of lift. The shock uses Bilstein’s bypass design, so the truck handles rough roads better and still stays comfortable on normal streets.

Inside, it runs a monotube setup with external bypass channels, which helps the shock manage heat and heavy movement way better than stock parts. You get more control when the truck loads up, when towing, or when the road is not that smooth. The click-style adjusters let you fine-tune compression and rebound — so you can set it soft, firm, or somewhere in between depending on how you drive.

The Bilstein B8 8100 Rear Right Shock Absorber comes zinc-plated to help resist surface wear, and the hardware lines up cleanly with factory mounting points. No crazy mods needed. Install it, set your preferred feel, and the rear end of the truck feels more planted, especially on uneven terrain.

This shock isn’t only for off-road runs — it also helps keep the truck steady in daily use. Less bounce, more control, and a setup that still feels natural to drive.
