🧾 Overview
The Timbren TORSEQ SES Rear Kit is a zero-maintenance load support upgrade designed for Toyota 4Runner (2003–2024) and compatible Land Cruiser platforms. It replaces factory bump stops with Timbren’s Aeon® rubber springs, which engage progressively under load to reduce squat, sway, and instability.
This system is built for SUVs that tow, haul gear, or run overland setups—providing support only when needed while maintaining normal ride quality when unloaded. Unlike airbags, there are no airlines, compressors, or adjustments required.
✔ Eliminates rear sag under load
✔ Reduces sway and improves handling when towing
✔ Progressive engagement (only works when needed)
✔ No maintenance, no air system
✔ Simple bolt-on installation
🛠 Installation
- Direct bolt-on replacement for factory bump stops. No drilling required. System automatically engages under load to improve stability and reduce sag.
