I’m having trouble finding a lift kit for my burban, it needs new leaf springs so I figured I’d just buy a lift kit. I wanted a 3-4in, rough country has a 6in for it but they also have a 4in labeled for a 2500, will the kit for the 2500 fit my 1500? Mine has the 56in rear springs

 

doubtful as higher capacity vehicles will usually have beefier axles. If 6" is too high for you, then use an adjustable spring hanger to fine tune your height.

 

the 1500 and 2500 will share the same front axle, rear axle might be different.
ive compiled some information about lifting a truck and make a post

i also put together a parts list to lift a truck 4" for under 700. this utilizes blocks for the rear. but rear springs imo arnt really needed for 4"
