Elite 30-563000 Rear Coil Spring Conversion Kit - Replace Air Springs for Smooth Ride | Perfect for Trucks, SUVs & Towing Vehicles

I bought these to replace the blown out airbags on my GX. You can read all over the internet for ways to spend more money to do this job, including buying all sorts of kits and struts and mounts and...you get the picture.I picked these up, having worked on a lot of vehicles over the years. Very easy install (as far as fixing cars goes). Remove old bags, use bottle jack to extend the space between the axle and the mount, install spring, let jack back down, put wheels on and drive.I have driven some rough roads since doing this, so far, so good. Also got new tires right after I did this repair and the GX drove like new afterwards. The best part is, the people I got the vehicle from sold it to me for a few grand less than they wanted because they factored in the quote from their mechanic for the repair. I think when I got these springs they were $115 or so. Well worth the effort on my behalf, my new DuraTrac tires were basically free because of this.TL:DR: They work, buy them if you are handy.
