The Complete Fix for Failing GX Rear Airbags
If your Lexus GX470 or GX460 has leaking or sagging rear airbags, this is the complete solution. This Master Suspension Conversion Kit replaces the factory airbag system and refreshes the entire suspension front to rear — all in one box.
This kit includes our Stage 3 Stock-Height Rear Coil Conversion, new front struts, KYB top hats, our OPOR comfort-tuned rear shocks, and a front leveling kit. The result is factory-correct ride height, improved durability, and a smooth, controlled ride on pavement and trail.
Why This Kit Exists
Customers asked for one order that:
- Removes the rear airbags
- Replaces all aging suspension components
- Preserves factory ride height and comfort
- Improves long-term reliability
This is that kit.
Metal-tech 4x4 pioneered the original bolt-on GX airbag delete conversion in 2007 and has refined it continuously for over 15 years. Most “other” conversion kits on the market today trace back to this original design.
What Makes Our Conversion Different
CNC-Machined UHMW Lower Spring Isolators
Our isolator mounts are machined in-house from UHMW — an aerospace-grade material used in orthopedic implants. It provides:
- Proper support of the spring pigtail
- Vibration damping
- No risk of spring breakage (common with poly isolators or rigid aluminum bases)
- This is the correct material for this application — and it is exclusive to Metal-tech 4x4.
Super Stock Rear Springs
We re-engineered the Prado 150 rear coil spring with:
- +5% increased spring rate
- Factory ride height maintained
- Made in the USA
This corrects the soft feel and bottom-out issues seen when using standard Prado springs on GX conversions.
Key Cones (Secondary Spring)
Co-developed over 3 years with Energy Suspension.
Dual-rate design provides:
- Progressive compression control
- Improved off-road articulation
- OEM fitment and long-term durability
- Made in USA
Protected under U.S. Patent No. 11,691,473.
Fitment
- 2003–2009 Lexus GX470
- 2010–2018 Lexus GX460
100% bolt-on. No welding or fabrication required.
(You will remove the TEMS/air suspension fuse during installation.)
