mancini or jeggs leaf spring xhd 340duster

You could get a set of AFCO's.

I have 20231M's on my Duster, this is how it sits with those in the back.



If you want it to sit a little higher, get the 20231's.

Only thing is that you need a different rear bushing because the AFCO's have 1" rear spring eyes. Energy Suspensions 2-2117g's fit the bill, they'll work with the stock rear shackles.

Only keep the /6 torsion bars if you plan on having a drag race only car. If you actually want your car to go around corners in a somewhat horizontal fashion, get a set of 1" bars. If you want it to handle like its on rails, get a set of 1.06's.
