I installed a 12" superlift suspension on my 86K10..
rear drive shaft i had lengthened and works fine...
front driveshaft length and angle were obviously a no go!
installed the 1" spacer at front of the 208 transfer case that was a recommended part to clear crossmemeber and will fix length...
i just finished installing the 12" superlift kit with 38s on my 86 K10 short bed...
Pros;
- purchasing kit got most of what needed
- very simple installation
- fast way to get truck up there!
Cons;
- ton of grade 8 hardware needed, is not included
- front driveshaft will need be...
