If you aren't wanting to go to high I would recommend a good quality leveling kit over a full lift kit. The 2015 2500's already sit a couple inches higher than the early 4th gens (10-12) so you'll be at the height of a 4-5" lift on one of the early trucks. Your best bet would be 2.5" or 3" progressive rate springs from Carli or Thuren, Bilstein or Fox shocks, and an adjustable track bar to recenter the front differential and avoid death wobble issues.

I would definitely stay clear of Rough Country, and SkyJacker on a 2500/3500. ReadyLift is okay for a cheaper leveling kit but still wouldn't be my first choice.

 

Brandon nailed it on the head. I wouldn't look beyond Thuren or Carli for a great quality set-up.

 

thanks guys!
going to look into those options

 

I have a BDS leveling kit with Fox 2.0 shocks. I did a full write up on here. Love it.

 

Anyone have any thoughts on zone 4.5 inch lift ?
Was looking into a BDS lift but garage I was talking to said to me about they sell and install zone lifts also and its a lot cheaper than bds.

 

Zone is essentially a cheaper version of BDS. They're owned by the same company and were created to compete with some of the cheaper lift brands out there like RCX. For a 1500 I think Zone is a great option however for a 2500/3500 I'd still be going with BDS far before Zone.
