I'm looking at getting a bigger lift for my 03 Cummins. I currently have a 2.5" rough country leveling kit with the blocks under springs in back. This was on truck when I got it and also has 35"-12.5-17's Kelly safari's. Truck handles fine now and 35's fill wheel wells good but do rub some on a lock to lock turn. I'm wonder what kit is best for the price and ride quality. Have heard some good things about BDS 8" long arm kit for about 2k. Also planning on running 37" tires, are there many choices and what do they run in cost? Leveling kit just doesn't seem like enough anymore but what will I sacrifice going 8" and 37's?

Stock wheels can run 37's. Just get some thuren arms.....it'll push the axle where it should be. Also get an adjustable trac bar to relocate the axle back to center.

 

I have eagle alloy wheels and most kits come with the adj trac bar. No one else has a lift that can give me some input? Should I move this to another section cus I usually get some response.

 

If you want 37" i'd say go with a 6" kit a buddy of mine just put 6" pro comp lift in his Ram and hasn't had a single problem with the truck in any aspect of the lift.

 

i have an 06 2500 with 6in SUPERLIFT!!!! running 37s, smooth ride and great off road!!!!

 

I bought my truck with a 6" lift on it and 37s not sure what for brand it is though unfortunately. Only ever rub if I'm turning and hit a bump just hit the dumb little plastic piece under the bumper

 

6 inch lift will work fine to clear 37s (may have a little tire rub), just need to pick a company. I like CARLI products but comes with a price. I am sure any of the other big name lifts are good.

a buddy of mine has 2.5" rough country coil spacers with 37/12.5/17 dick cepek fun countrys, only rubs on full lock turning right. Synergy makes the starter kit for 37" tires, and from what ive heard its a reasonably priced quality kit.

that BDS kit is worth every penny, but it isn't a 2k kit once you have played with all there options!
