Metal-tech 4x4 GX470 Rear Coil Conversion Kit Stage 2 w/ Key Cones

Lexus GX470 Rear Coil Conversion – Stage 2 Kit

Airbag Delete | Designed for Lift Kits or Customer-Supplied Springs | 100% Bolt-On | Made in USA

Eliminate Your Rear Airbags — The Right Way

This Stage 2 kit is for Lexus GX470 owners who:

• Are installing a rear lift kit
• Already have aftermarket rear springs
• Want to choose their own spring rate or ride height

If your GX470 has leaking or failed rear suspension airbags and you plan to run a lift spring, this is the correct conversion kit.

This kit removes the airbags and properly converts the vehicle to rear coil springs.

What Stage 2 Includes

• ✔ CNC Bolt-On Spring Locators
• ✔ CNC Machined UHMW Spring Tail Isolators
• ✔ Patented Key Cones (Dual-Rate Secondary Springs)
• ✔ Complete hardware kit
• ✔ Install guide and video support
• ✔ US-Based direct support from the inventors of the GX airbag conversion kit

Everything needed to remove your rear suspension airbags.

Rear coil springs are NOT included in Stage 2.

Why Choose Stage 2?

Stage 2 is ideal when you are pairing this kit with:

• Aftermarket lift springs
• Performance suspension systems
• Custom build configurations

It gives you full flexibility while still using the properly engineered mounting system that made the original GX conversion possible.

Patented Key Cones – Included

Toyota calls them “secondary springs.” Many conversion kits ignore them.

We don’t.

Key Cones were developed by Metal Tech 4x4 in collaboration with the #1 polyurethane suspension manufacturer in the United States over a three-year engineering process.

• Dual-durometer high-performance polyurethane
• Soft initial engagement
• Progressive lower body for end-of-travel control
• Increased suspension stability

100% Made in the USA.

Protected under US Patent No. 11,691,473.

CNC Machined UHMW Spring Tail Isolators

This is where many conversions cut corners.

Polyurethane isolators can be too soft and allow the spring pigtail to crack over time. Aluminum provides no vibration isolation and can introduce corrosion between dissimilar metals, accelerating wear on the spring.

We machine ours from UHMW — the same material used in orthopedic implants.

• Full pigtail support
• Vibration isolation
• No cracking
• No metal-to-metal contact
• No corrosion issues
• CNC machined in-house

This ensures your chosen spring performs properly.

100% Bolt-On Installation

• No drilling
• No welding
• No permanent modifications

Remove your rear suspension airbags. Install the locators and isolators. Install your rear springs. Pull the suspension fuse.

Estimated install time: 2.5 hours

We provide full install documentation and video guidance.
