i've attached a pic of the strip below. my dad has some of the mrk items - their prices are a complete rip off for what you get. $40+ for a piece of vacuformed lexan that looks like a 6 year old cut it out with scissors is a bit much.
I just bought the front spring on a 05 SRT RC for my 05 QC, they will lower mw 1.5" as for what they will do for your truck you might try to contact Tony (JTSVP) at 704-214-7849. He is the SRT-10 GOD!
