Improve load support, handling, and ride stability with the Timbren FRTT1502D Suspension Enhancement System. Designed for severe-service applications such as slide-in campers and salt spreaders, this rear suspension kit helps reduce vehicle squatting, sagging, suspension settling, and trailer sway. Its high-performance rubber springs automatically adjust to changing loads and road conditions while cushioning road shocks for a more controlled driving experience.
Timbren’s rubber suspension technology has been trusted since 1965 and is engineered for dependable, maintenance-free performance. Unlike air-based suspension systems, the SES kit uses no airlines, compressors, or fittings that can leak. Once installed, the rubber cushions provide continuous support without manual pressure adjustments, making this a practical upgrade for work trucks and vehicles that regularly carry heavy or uneven loads.
The Timbren FRTT1502D is designed for rear suspension applications with a weight capacity of up to 7,000 pounds. Installation requires no drilling or airline routing and can be completed in minutes using basic hand tools. This kit fits select 2006 and 2007 Ford F-150 applications, including models such as the STX RWD, and is backed by Timbren’s limited lifetime warranty. Verify vehicle fitment before ordering to ensure compatibility with your specific configuration.
