Does anyone now if the spacers for coil spring will fit a 76 E150 van with twin I-beam,Ian running 31 /10.5 /15 .Would like a lift of 1 to 2 "so it doesn`t bottem out .Or if their is a set of truck coil springs that would fit.The springs where replaced within the last month.
I think the preference between twist-in or non strictly depends on your driving style. If off-roading, driving over a lot of rough roads or potholes, then don't go with the twist-ins. If it's a daily driver around town, don't worry about, you won't have the side to side or compression/release movement of the spring to loosen them.
You can pick up around an 1" or maybe a bit more by unbolting the bottom spring retainter (big nut in side spring on bottom) and shimming it up. I guess also you could replace the bolt (with a really good quality one) with a longer one and shim it as high as you wanted to. No offense but those twist in things are a crime against nature and not, IMHO, a substitute for the right spring. Your camber is going to go to heck after this adjustment. GL
The twistin work just fine on the road.
On the sand dunes not so good
I have the inch and a half rubber booster. I lifted the front of my truck. I sprayed the spring with WD 40 and tapped it in with a rubber mallet.
