Product Details

The Timbren Industries HIR338 SES (Suspension Enhancement System) is a hollow rubber spring suspension upgrade designed to eliminate squat, sway, and rough ride quality when towing or hauling heavy loads. This system replaces traditional metal helper springs and air bags with maintenance-free Aeon hollow rubber springs that engage progressively as load increases.

Key Features:

  • Aeon hollow rubber spring technology provides progressive load support up to several thousand pounds
  • No maintenance required - no air lines, compressors, or leak-prone components
  • Installs in approximately 30 minutes with basic hand tools, no drilling required
  • Reduces rear-end squat by up to 80% when loaded
  • Improves vehicle stability and control when towing trailers or carrying cargo
  • Works with factory suspension - engages only when needed under load
  • Lifetime warranty on Aeon rubber springs

The SES system mounts between the frame and axle, remaining dormant during normal unloaded driving. When weight is added, the springs compress and the Aeon cushions engage to provide supplemental support exactly when needed. This design maintains factory ride quality while delivering commercial-grade load support.

The vent broke where the control arm screw threads in the second time I closed it. product appears. more brittle than the stock one. Good thing I'm not on the road

For a little unsure about whether a second package was coming, but Customer Service cleared it up.

N/A

Great price and quick delivery. The only issue I had was that I did not receive a shipping confirmation and tracking info. I had to contact customer service and they weren't even clear on shipping info. While I was waiting for a reply, the tire showed up at my house. I received shipping confirmation the day after it arrived.

awesome prices

Finding what I wanted and the ordering process was easy to do.

Fast shipping. Good communication via email. Everything as expected. (Not always as common as it should be these days.) Thanks.

Great experience. Will buy from again.

So easy to order from.
