Metal Tech GX470 Rear Coil Conversion Kit Stage 1

Current Stock:

Product Description

Metal Tech 4x4 has introduced a complete bolt on rear coil conversion kit for your GX470 to get a true 2" lift with a coil spring and no longer have to deal with leaky air bags.  With the Lexus GX470 becoming popular among the off road community, people are looking to put a suspension lift on these very capable 4x4s.  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.  Another problem when a person lifts the front of the GX470, the air bags in the rear have to be at their max ride height to keep a level stance which creates a very harsh ride.

The Metal Tech 4x4 GX470 rear coil conversion kit solves all these issues by removing the air bags and in place: stock height coil spring or 2-3" lift spring can be put in place.  We achieve this by reproducing what Toyota developed for the Toyota Land Cruiser Prado, 4Runner and FJ Cruiser rear suspension setup.  This basic kit comes with the spring locator and the polyurethane spring isolator.  You will need to source the Prado secondary spring isolator which can be found at your local Toyota dealership or junk yard.

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 or for those that are looking to lift the rear end.  This is kit is 100% bolt on with no additional modifications required.  If your intended purpose to is lift the rear end, you will need to disconnect the ride height control computer that is located in the driver side kick panel and the fuse/relay inside the engine bay.

Kit Includes:
  • 1 Pair of Spring Tail Isolators
  • 1 Pair of Spring Locators
  • Mounting Hardware

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

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

Estimated Install Time: 2.5 hours

  1. Nice Kit! 5 Star Review

    Posted by on Jun 1st 2019

    I installed using the basic kit, Moog 81045 Coils and Toyota FJ Spring Tail Isolators. Install was very straightforward and relatively easy except for getting the nut and washer under the spring perch. (Hint - Tape them together and put them into an open end wrench.). Afterwards, the ride is improved with factory height. Should have done this a year ago and not waited for my air suspension to quit. If you decide to pull the air compressor, accumulator and solenoids, and sensors with all the associated brackets and lines, that is harder than the spring swap, but cleaner when done. The swap to coils is well worth it.

  2. Game changer on 4th gen 4Runner 4 Star Review

    4 stars because I haven't seen how it performs long term, but this kit and springs are way better than the unreliable air ride system. I was able to keep XREAS after the swap even with a 2 inch lift.. that system is next to go.

  3. Love it! Love the ride with no more airbags 5 Star Review

    My airbags tanked on the GX and this was to only affordable option. So glad I went with this kit. Instructions were clear and detailed to the T. Everything went in perfect. Paired this with some FJ Cruiser stock springs for a slightly taller rear end. Couldn’t be more happy with the feel and ride. Not to mention no more air bags and dash lights to deal with.

  4. Nice Kit 5 Star Review

    This is kit works well, especially if you would like the spring to securely rest on urethane bushing and not rub axle mounting point metal to metal. I used this kit with MOOG 81081 coil springs. Truck rides very nice, I would say better that it was with air suspension.

  5. Lower spring seat and block 5 Star Review

    Posted by on Apr 27th 2017

    Worked perfect gives u peace of mind that the spring won't pop out from factory position. And no spring noise because of the isolator.. It's a must when removing rear air bags from the rear on a gx470

  6. Nice Product. 5 Star Review

    Posted by on Apr 17th 2017

    Installed this on my 04 Lexus GX470. It fit great, had good instructions. After a year zero issues. Great product to swap to coil springs and ditch the air bags. Even though I bought it with out the upper spring seat isolators you really should get them. Used or new from someplace.
