two things to keep in mind, a lift kit won'tr make it any wider, will just raise things!, if anything Ir could make it more narrow, as some might RAISE the angles on a arms and that will suck the wheels IN some rather than push them out!
next is IF you get spacers MAKE sure you use good lock tight on the treads when mounting them and CHECK them every so often, they are known to walk loose, its why there illegal on ON road cars and trucks in most places!
and NOT saying to DO this, But lift kits are simple things, MOST machine shops can make them for a SMALL fee, if you BUY a pre made one, you could (WINK WINK)
take the parts to a machine shop, have them copy(or in my case make stronger parts) and then return the kit ?? IF you wished to be this way!
I saved my kit, but I did have a friend with a machine shop, make me all parts out of stainless steel and MUCH thicker and stronger design on all parts, been on 15+ yrs and holding up, the KIT parts I bought were cheesy and I doubt they would have lasted 5 yrs with all the abuse I gave this atv and overloaded it so many times
SO food for thought maybe??
ain't much to these kits to be honest!
