2.8 HD Series 3-Way Adjustable Rear Coilover Kit | 2021+ Bronco

Overview

Increased oil volume, more damping control, and better heat management compared to a traditional 2.5- without the size, weight, or price tag of a 3.0. Engineered from premium-grade materials and designed by off-road enthusiasts, the BRBN 2.8" HD Rear Coilover is built to thrive where the trail is at its roughest. We took it beyond the drawing board — subjecting it to independent dyno testing against a major industry competitor — and proved it delivers a broader adjustment range, more consistent damping, and superior control under extreme conditions. This is the rear suspension solution for drivers who demand more than “good enough.”

Intended Use
The HD spec rear coilover is tuned for versatility and abuse resistance. Whether your Bronco is a fully loaded daily driver, a weekend overlander stacked with gear, or a dedicated off-road build trailered to the course, BRBN’s rear setup offers the adjustability and durability to keep pace with your adventures. The rear HD coilovers come equipped with a 4.8 KG spring rate (vs our 4 KG spring rate on the standard 2.8 series). This is ideal for carrying a consistent additional 400-800 pounds in vehicle accessories (racks, aftermarket bumpers, recovery gear, etc). 

Our 2.8 Series Coilovers will bring you closer to 3.0 performance than any 2.5 on the market.
