Were putting a stage 2 FFI steering box into a 71' Challenger and was wondering if the fast ratio pitman arm is worth putting into the car? Has anybody driven with one of those in a mopar? Anything diffrent than the usual driving/ parking /cornering with this steering upgrade?

Here is some into on the car:

older suspension rebuilt with only 500 miles put on it in last 12 years
440 auto with HP exaust manifolds
late model b-body disc brakes
stock front swaybar
15x8 rims with T/A radials
car is dropped 2in front/2in rear lower blocks
all parts on front suspension were stock stlye replacment parts for the rebuild


Hope someone who has driver a car with fast ration can give us an idea on what to exspect on this conversion.

I have the fast ratio Idler AND pitman in my Charger. TTI says their headers wouldnt clear, but mine do.
I have the Stage 3 Firm Feel steering box too. The turns lock to lock went from 3 1/2 down to about 2 5/8 lock to lock when I added the FR arms. PLUS the steering effort went up a little. FANTASTIC upgrade over the usual overboosted Mopar schmere.

that sounds good. What are the specs/year on your charger?

I did the same with my 69 Charger. Doug's headers clear as well. Rb for sure and B more than likely. Hope to drive it this week and will be autocrossing in Vegas. Mike

That sounds cool. We would have like to have done las Vegas , but the vehicle transport was running late, so it's a no go. Would like to make the spring fling with it though.

We have a few sets of the magnum force adjustable tubular control arms, tempted to pop em on early and see about raising torsion about an in in front.

I've heard when you run their fast ratio pitman you are also supposed to run their power steering box as well. Something about them moving the lock points so you can't over-twist the faster ratio pitman...?

nice ride you have there. my driving style is a bit more agressive than most, so this upgrade sounds like it would be perfect for me.

I like the fast ratios....harder to turn though....

Thanks Mig
Good luck!

Fast ratio means that for each revolution of the steering wheel, the tires move further. The 24 to one manual would be S L O W ratio. Whats that? 5 or 7 turns lock to lock? Most Mopar power steering boxes are 3 1/2 turns so they are much "faster" than the manual boxes but you dont notice the increased effort because of the power assist. Take off the pump belt and try to steer! The longer pitman and idler that ARE the Fast Ratio variety make the tires move faster and further, but once again, the power assist hides some of the increased effort. My Charger feels like a manual 16 to one box. Just right!

thanks for the info and specs. We will probably just get a 1973+ std pitman to replace it and wait til later on and see if I really needa fast ratio steering arm when the car gets more upgrade parts.
