Lifting a Duramax

[oldtimer]

I have been looking to buy a Duramax lately but I want to get a lift but not a 6 inch suspension lift. I have looked for a 3 or 4 inch lift but don't know if they are any good. Please give your opinion on what to do?

Rancho makes a 4" suspension lift for the 2500HD Duramax. It's a quality product, and when paired with the Rancho 900 adjustable shocks - the ride is better than stock.

 

The Rancho 4" can accommodate 305's without a problem. You could probably squeeze 315's under it but you would have limited flex

you can get a six inch too!
