Product Description

Metal Tech 4x4 has introduced a complete bolt on rear coil conversion kit for your GX470 to eliminate leaky air bags. The GX470's came with factory air bags in the rear which are prone to leaking over time and can be very expensive to replace. 
This STAGE 3 KIT uses a STOCK HEIGHT SPRING for people who only want to replace the air bags and keep their vehicle Stock height. For lift springs use the Stage 2 kit with a lift kit sold separately. 

The Metal Tech 4x4 GX470 rear coil conversion kit solves all these issues by removing the air bags and replacing with new stock height coil springs   We achieve this by reproducing what Toyota developed for the Toyota Prado, 4Runner, and FJ Cruiser rear suspension setup.  First there is a bolt on spring locator that mounts to the axle housing with a polyurethane spring tail isolator that slips over for the bottom of the coil spring to rest on. Then we use a brand new stock height coil spring with a factory Toyota Prado 120 secondary spring isolator that keeps the spring in place and acts as a secondary spring when the axle comes in hard contact when coming off a ledge.

This rear coil conversion kit is designed to be used for people who want to get rid of their air bags all together and go to a traditional coil spring at factory ride height.  This is kit is 100% bolt on with no additional modifications required. You will need to remove the fuse/relay inside the engine bay, as well as pulling the TEMS fuse in the dash

Kit Includes:
  • 1 Pair of Spring Tail Isolators
  • 1 Pair of Spring Locators
  • 1 Pair of Prado 120 Secondary Spring Isolators
  • 1 Pair of new stock height coil springs 

GX470 Rear Coil Conversion Complete Kit fits the following vehicle(s):

  • 2003-2009 Lexus GX470
  • 2003-2009 Toyota 4Runner with rear airbags

Estimated Install Time: 2.5 hours

  1. So goodbye to the bouncey GX470 rear end 5 Star Review

    Posted by on Mar 8th 2019

    After driving the GX470 for 3 months with the rear end floating and bouncing around I found this site after a Google search. I'm so glad I bought this kit along with a pair of KYB shocks for an 04' 4Runner (thanks John). This thing rides better at 133k miles than when I bought it 5 years ago. Thanks to John and the Metal Tech crew for building this kit. It is so much better than stock.

  2. DO THIS! 5 Star Review

    Posted by on Jul 31st 2018

    As if waiting for 2 minutes to drive the car from the start wasn't annoying enough, apparently every 40,000 miles you have to replace the air bags in this stupid adjustable suspension (that adjusts itself back to normal height at about 5 MPH anyway). This is the dumbest option any car manufacturer has ever offered... Do yourself the favor of throwing these springs under there, and you too can drive with a functioning suspension system like everyone who didn't buy this SUV! The parts fit perfectly, and the instructions for installation are quite helpful, right down to which fuses to pull in order to deactivate the dashboard display and the air compressor. This is the best thing I ever did for my GX.

  3. Wonky Airbags Gots To Go! 5 Star Review

    Posted by on Jun 19th 2018

    Do you have a GX470? Do you come out in the morning and the rear end is noticeably low? Does your compressor turn on every time you start engine? Does the rear end hit the bump stops every time you hit a bump? Does the rear end feel like it's wonky and weak?

    Then you need to buy this conversion kit!!

    My GX is back to it's former glory! No more shaking at 65-75MPH and it rides like new!

    Thanks Metal Tech!
