Timbren Industries Expands Timbren SES Lineup
Timbren Industries announced the official release of the FRBRG Timbren SES (Suspension Enhancement System) kit. This latest addition to the Timbren catalog is precision-engineered for the 2021-2026 Ford Bronco (Full-Size) and the 2024–2026 Ford Ranger, providing a high-performance solution for increased towing and hauling stability, Timbren said in a recent release.

The FRBRG kit utilizes Timbren’s signature Aeon hollow rubber springs, designed to deliver a progressive spring rate. This system engages only when the vehicle is under load, effectively eliminating rear-end sag and maintaining a level vehicle profile, the company said. By providing additional support to the rear suspension, the kit significantly reduces body roll and improves steering and braking control during heavy-duty transport.
Designed as a “set-it-and-forget-it” alternative to complex air suspension systems, the FRBRG requires no air lines, compressors or manual adjustments. It is built to withstand the rigors of heavy work cycles while ensuring the vehicle remains stable and predictable, even when pulling trailers or carrying maximum payloads, Timbren said.
Key features of the FRBRG kit include:
- Eliminating Squat: Automatically eliminates rear-end sag under heavy loads
- Enhanced Stability: Significantly reduces sway and body roll for improved safety
- Progressive Support: Hollow rubber springs deliver a smoother ride by absorbing road shocks and vibrations
- No-Drill Installation: A complete bolt-on solution that installs in a matter of minutes with basic hand tools
