Upgrade your truck's load-carrying capability with the 11C Silverado/Sierra 2500/3500 2WD/4WD Rear Timbren SES (Suspension Enhancement System). Designed specifically for compatible Chevrolet Silverado and GMC Sierra 2500HD and 3500HD models, this heavy-duty rear suspension upgrade helps eliminate rear-end sag, reduce excessive sway, and improve overall vehicle stability when towing or hauling heavy loads.
Unlike traditional airbag systems, the Timbren SES requires no air lines, compressors, or maintenance. The advanced Aeon® hollow rubber springs engage only when additional support is needed, providing a smoother, more controlled ride while maintaining factory ride comfort when the truck is unloaded. Whether you're towing a trailer, hauling construction equipment, carrying campers, or transporting heavy cargo, this suspension enhancement system delivers reliable support and improved handling.
Built from durable, high-quality materials, the Timbren SES is engineered to withstand demanding work environments and harsh road conditions. Installation is quick and straightforward using existing factory mounting locations, making it an ideal upgrade for work trucks, fleet vehicles, RV owners, contractors, farmers, and off-road enthusiasts.
If you're looking for a dependable suspension solution that improves towing confidence, minimizes suspension stress, and extends the life of your factory suspension components, the Rear Timbren SES is an excellent investment for your Silverado or Sierra HD truck.
