Marketplace Auto Parts Rear Air Spring to Coil Spring Conversion Kit (Converts Air Springs to Coil Springs) - Compatible with 2003-2009 Gx470

I installed this on my 06 GX470 with KDSS and it worked perfectly. Comes with top AND rear spring isolators and maintains the factory ride height. I did not bypass the KDSS system at all when working on my GX470 and everything fit great. Never had to disconnect the Sway bars at all, just take the wheel off, the two rear shocks, and then the rear air suspension comes out and gets replaced by the coils. Easier to do on a KDSS GX than one without KDSS.

I installed these springs on my 2007 GX470 after having some issues with the factory air suspension system. Just a little research (youtube) and these were easy to install with a helping hand. I did not like the lack of isolation for the lower spring perch but I had these lower springs mounts a friend gave me (see photo) and they worked great and really help to keep the bottom portion from moving around should I ever get off the pavement for any serious offroading :)

The springs are doing well on my 2007 Lexus GX470. It's no surprise that there's a very little bit more sway than with my old airbags, but these things will never crack and leak air! They were easy to install following instructions and tips from a few YouTube videos.

My order is missing both coil spring isolators for one of the springs. Springs look ok, but stuck without the isolators. Hope the seller will resolve this issue.

I liked this replacement. It took me 2 hours to complete. Biggest issue I had was not having the lug nut key to remove my wheels. Bought spiral removal kit and final removed lug nuts. The instructions included were the wrong instructions for the kit. But there are plenty of videos on line to show you what to do.

This kit arrived quickly and was in good order. The instructions were laughable. Since I just installed I can’t comment on the durability but the function seems good. Only gave 4 stars because instructions were lame. This was a surprisingly straightforward project. If you have the tools and enough skill to say change your brakes, you probably can do this job. The whole job took a couple of hours. I’ll share my process and a couple of tips where I struggled briefly. 1 Remove spare tire to give extra working room. Do this first as it is easier when the vehicle is lower. 2 Turn the key on without starting the engine and use the button on the center console to turn off the air suspension. There should be an off icon on your dash. Remove the key. 3 Chock the front tires. 4 Jack up the vehicle with a floor jack placed in the center of the differential housing. 5 Place jack stands under the frame of the vehicle in front of the rear tires, one on each side. 6 Lower the jack enough so that the vehicle rests on the jack stands but not enough to lower the rear end too much. 7 Remove the rear tires/wheels. 8 First TIP - Remove the bottom shock bolt and remove the shock from the bottom mount point. Do this while the axle is still fairly high as you don’t have enough travel on the shock with the axle lowered. 9 Disconnect the air lines that run to the air springs from the air cannister. There is a keeper that can be disengaged by squeezing and sliding down the line. At this point the air line is held in place by another keeper inside of the fitting. I saw a video that showed how to use the first keeper to remove the line from the fitting. I was unable to make this work. Second TIP – An awl or other thin, pointed device can be used to disconnect the air line. Pull on the air line slightly to keep tension on. Use the awl to push outward on the tab inside of the fitting. There are two tabs inside of each fitting. If you keep tension on the line while pushing on one tab first then the other, the air line will slide right out. The whole point here is in case you want to keep the air lines so that you can go back to the air suspension later if you want. If you don’t care, you can just cut them off. 10 Disconnect the air lines from the clips on the frame. 11 Shine a light up on the top of the air spring from underneath the car. From the side of the car, in the wheel well, look through the opening just above the frame. You will see the clip that holds the air spring in place. I used a piece of bailing wire about 2’ long, bent just right to snake in there and thread through a small hole in the top of the clip and back out to the wheel well. Once you have both ends of the bailing wire in your hand, a little tug will pull the clip out. Repeat for the other side. 12 Lower the jack down until the axle housing stops dropping. 13 At this point, you should have plenty of room to remove the old air springs and the air lines that are still attached at the top of the air springs. You might want to save the clips also in case you want to return to air springs in the future. 14 If your car is like mine, you will want to clean the dirt from the top of the axle housing where the new spring is going to rest. 15 Place the rubber piece for underneath the spring on top of the axle housing in the correct location. 16 Third TIP – A small bottle jack placed on top of the axle housing and under vehicle frame will allow you push down on the axle housing enough to place the rest of the spring assembly in place. Do this on the other side as well. Remove bottle jack. 17 Once the springs are in place, use the floor jack to slowly raise the axle housing while check the springs are staying in place as you go. Once you have them held in place, you can jack more aggressively. 18 Raise the axle housing up to the point where you can reconnect the lower end of the shock absorbers. 19 Once the shocks are re-installed, re-install the tires/wheels. 20 With the wheels re-installed, jack the car up enough the remove the jack stands. Lower the car back to the ground. 21 Relocate the spare tire back to its storage location. 22 Remove one fuse from panel under dash. Third one from upper-right. I forget what it was labeled. 23 Remove two fuses from panel in engine compartment. One 50 amp labeled AIR SUS. One 10 amp labeled AIR SUS. Remove relay from auxiliary panel on side of fuse box. Labeled AIR SUS. 24 Test drive. I hope I didn’t leave anything out but it is possible.

Received and installed today. Isolators included for top AND bottom of springs...not noted in description. Ride is smooth, not as much sway as with air springs. Glad I watched several YouTube videos as these springs don't include information about deactivating air suspension warning messages (remove fuse 3rd from far right in top row and air suspension relay under the hood in small auxillary box). I also removed / unplugged console switch and replaced with OEM cup.

Got the spring kit to replace my air bags and it fit fine and price was good too. I in used a icon coil spring conversion kit and I'm happy with how everything fit
