The Timbren FRTT1504E Suspension Enhancement System is engineered to strengthen the rear suspension of 2015-2026 Ford F-150 trucks. Designed specifically for high center-of-gravity loads such as truck campers, service bodies, or salt spreaders, this system helps deliver improved stability while hauling heavy gear. Timbren’s patented Aeon® hollow rubber springs progressively engage as weight is applied, helping reduce rear-end squat, sway, and body roll during towing or hauling. The system remains inactive during normal driving to maintain ride comfort when the truck is unloaded. This rear kit includes adjustable spacers and heavy-duty mounting hardware for proper fitment and installs easily with a bolt-on design. Once installed, the system requires no maintenance and is backed by Timbren’s lifetime warranty.
