I have a '52 Chevy truck with a Mustang II and 4 Link. I have an Air Ride set up and, while I like dropping the truck, I hate futzing with the bags. And it's got a lot of body roll. I tried an anti-sway bar, but the angles suck and I keep snapping heim joints. So, I am going to just ditch the bags and go coil overs. Question: is there some tips to measuring for these? Like, width, height, etc? I'm assuming I just need to set the truck at ride height and then measure the space I have? Thanks for the advice!
Yes, measure at ride height. Depending on which MII front end you have it may be easy to convert. Most vendors offered the coil over option and you should be able to buy the correct lower "A" arm and swap it out. For the rear you need to fabricate the coil over mounts and weld them in.
Set the truck at ride height and measure the distance between top and bottom bottom mounts, that is the compressed distance of the coil overs you require bearing in mind that at ride height, they need to be approximately 1/3 compressed to allow for compression and extension whilst driving.. Next you need to factor in weights front and rear to determine what rate springs you require. If there is a lot of body roll it sounds like there is a lot of weight transfer through the suspension (Air bags), it should not be like that. The individual bags need to retain air and compress, not let the air bypass the bag and transfer to the opposite side. On another note, if you are breaking heim joints on the sway bar ends something is seriously wrong with set up. Post some photos of current configuration, it might be a simple fix. This is Air Ride set up as well.
