coil spring lifters
the rims are stock size if there 15" and the tires should fit with out the lift, though its better to have the lift
it is the length and diam off te wire and the material off te wire
Anything over 400 lift , you will start having problems. Pulling studs out of heads, coil spring bind, rocker arm problems. Ect...
Coil spring boosters are only for coil springs, NOT those found on struts. Struts are engineered to function in only their original configuration and should not be modified. Look into finding new struts that will fit your application.
You can get a set of coil spring blocks that will give you a decent amount of clearance for larger tires.
look at rear end axle, if it has leaf springs or plain coil springs then no. if it has rubber airbag lift system instead of leaf -coil spring then yes
I have 31.5 x10.5 on my 93 F150 without a lift kit, they fit without a whole lot of room to spare
depending on the type of head anywhere from 550 to 600 NEW ANSWER- YOU said stock, so in that case anything over 400 lift will cause spring coil bind, and brake the spring. NEW ANSWER- somewhere between .450 to .500 should be max lift before any binding on 87+ heads, stock lift is between .417 and .430 with 1.5 ratio stock rockers
compress the suspension and measure. Fully flex the suspension and measure. You will be measuring the length between the two shock mounts. At that point you can order whatever shock you need based off of the length and not vehicle specific.
Possibly The SE coils and Rubicon Coils are the same length but the Rubi coils have a stiffer spring rate and you could gain 0 to 2 inches of lift if your springs are sagging
No you need coil spring spacers or to replace them with heavy duty springs from a truck you will also needhub spacers so it will not rub
