  • Additional Information
Metal Tech 4x4 has introduced a complete bolt on rear coil conversion kit for your GX460 to get a true 2" lift with a coil spring and no longer have to deal with leaky air bags.  With the Lexus GX460 becoming popular among the off road community, people are looking to put a suspension lift on these very capable 4x4s. The GX460'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 GX460 is the air bags in the rear have to be at their max ride height to keep a level stance.


The Metal Tech 4x4 GX460 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, 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.  On top we use Key Cones that keeps the spring in place and acts a secondary dual rate 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 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.

Original Coil Conversion Kit 2.0 by Metal-tech 4x4 

 

Original Coil Conversion Kit 2.0 by Metal-tech 4x4. In late 2007 Metal-tech 4x4 invented the Original bolt-in conversion kit for Lexus GX's. Now, 15yrs later we have updated the design with an easier to install and higher performance machined aluminum body and precision machined custom coil isolator. The key difference is the top of the new aluminum centering puck featuring a recessed countersunk bolt mount, creating a flat striking face for the secondary spring (cone thing inside the top of the coil spring). This new flush face keeps the bolt from damaging the secondary spring on contact. In addition, the hardware included in the kit features a slim nylock (aircraft nut) that is much easier to install than the previous design. The kit is 100% CNC machined in the USA from US made material. The isolator used in the Metal-tech 4x4 kit was updated in 2022, we eliminated the rubbery off the shelf poly isolator.  Soft poly isolators can be too soft for some springs pigtails, leading them to crack the spring.   We moved to a CNC machined isolator cut from UHMW (Ultra High Molecular Weight Polyethylene). This is a high-performance aerospace plastic that is perfect for this application. By custom machining the parts in house at Metal-tech 4x4, we were able to increase the flange size to better support the bottom of the coil spring. Most importantly with the UHMW machined isolator is the springs pigtail is properly supported with no chance of it cracking the spring.  

 

History of the coil spring conversion kits: 

 

In 2007 almost no one wheeled a Lexus GX470 let alone modified them. We had a local customer ask if there was a way to lift his GX470, always curious we offered to look at it. We immediately identified it as being what is now common knowledge, but at the time it was not, that the truck was really a Prado120. We realized a suspension kit for an FJ Cruiser or 4th gen 4runner would probably install onto it. However, we had to figure out how to remove the rear airbags, defeat the electronics that would expect the bags to be there, then build a bolt-on solution for the lower airbag mount. We proceeded just because it was an exciting challenge, and the customer was down for us to try on his expensive 2yr old Lexus. It took us close to half a day to figure out how to pull the first airbag! We can remove one now in about 3 min. But again, no one was sharing how to do this back then. Next was to design a bolt-in solution for the conversion kit. The kit needed to be easy to install and center the spring correctly. We made the first bolt spring mount and installed it. It worked so well on the trail that we knew we had something to help other GX owners convert from airbags. We released the first bolt in conversion kits in 2008 and sold a whopping total of 2. That same year we released the first ever made armor for the GX with bolt on sliders. Again, sold 2 sets of sliders for that year!  However, over time with more GXs getting built, our conversion kits took off. Most of the competitors today that sell a bolt in conversion kit used to just buy them from us. Thus, why we call our kits the Original Coil Conversion Kit. Now it's been completely redesigned to the 2.0 version with all the new features of the precision machined parts. 100% Made in the USA. 

Key Cones

Dual Rate high-performance polyurethane upper spring cones for rear mount applications. Toyota calls these “Secondary Springs" (commonly mistakenly called isolators by some). Key Cones were developed by Metal-tech 4x4 and Energy Suspension over a 3yr collaboration. This dual rate secondary spring is featuring Energy Suspensions proprietary polyurethane in two different durometers. The top accordion tip is soft when engaged and the lower body is firmer as your suspension nears the end of travel. Far superior to the single rate basic rubber found in the OEM application. Key Cones unlock hidden performance on your truck.

100% designed, engineered, tested, and made in the USA.   **Patent Pending**

(One truck uses one pair)
