Unstable loads while towing and hauling don’t just make for an uncomfortable ride. Difficult handling, rear sag, and corner sway create dangerous driving conditions — for you, your passengers, and other vehicles.

Whether you’re towing your RV across the country or hauling hay down the highway, our Timbren SES kits level your load, making for a safe, controlled ride so smooth, you might forget you’re towing altogether.

Whether you’re towing your RV across the country or hauling hay down the highway, our Timbren SES kit is designed to improve suspension performance for the 2024-Present Toyota Tacoma, Land Cruiser 250, and 2023-Present Toyota Sequoia. It acts as a helper spring, leveling your load for a safe, controlled ride so smooth, you might forget you’re towing altogether.

What makes Timbren SES kits different from other suspension enhancement systems? Unlike traditional air bag suspension systems, such as AirLift or Firestone air bags, Timbren SES kits require zero post-installation maintenance. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway. No leaks, no adjustments—just durable, long-lasting support for every haul.

If you're looking for a reliable alternative to other helper springs or air bags, this SES kit provides the strength and stability needed for all the towing and hauling you do.
