I'm gonna get a set of 1ton rears real soon. My question is this... I have a set of 15/35/15 Boggers I want to use in myupgrade on my 88 K5. Can I use these tires or do I have to get a 16 inch tire and wheel combo? Will my 15"ers clear the calipers on a Dana 60? Or can I grind the calipers to make them work. Also, what about springs. Are there any differences between 1 ton springs and 1/2 ton springs. I'm gonna get a set of 6" superlift or skyjacker springs for the lift. I thought 1 ton springs are wider than 1/2 tons. Thanks in advance for the feedback.
