Looking to lift my 1997 silverado c2500. Looked at kits like rough country but couldn't find one compatible with the (2500)part of my truck... does it matter? And is there anything else I would need to change? Like break lines and things of that nature

 

Cant say for sure, but three inches aint much. It's what I put on my Jeep with no modifications but larger wheels/tires, so I could make it down the Rubicon Trail, before they leveled it so much you can drive a pickup down it now. It was solid, thick granite rock back then. Tear the hell out of any larger vehicle. LOL!

Had a guy who didn't care run a Suburban through the "Little Sluice Box". Ripped it all to shreds, but he made it!!!
