Shock changes, spring changes, ladder bar changes. This spring we're installing an 8" that should stall in the 5500-5600 range. Hopefully that will bring my dads Duster alive. I think the car grabbed a couple high 1.4's, but most of the time it was in the low 1.5's. I'm thinking that high/mid 1.3's should be the norm. We'll see.....
