Firm Feel's new Fast Ratio Pitman Arms are forged similar to the T/A Challengers and AAR Cuda's. This changes your stock steering into fast ratio steering. Your stock power steering ratio is 16:1, (3 1/2 turns lock to lock), with the fast ratio pitman arm your ratio is ~ 12:1, (2 3/4 turns lock to lock). These arms fit your power steering (and manual steering) with either SMALL OR LARGE SECTOR. Our Fast Ratio Pitman Arms are manufactured with universal spline timing to insure correct steering wheel centering in every application. Now you can benefit from the same fast ratio steering once only found on rare AAR Cudas or T/A Challengers. We also have a full selection of stock pitman and idler arms for most A, B, E, and F body cars.
NOTE: about "Ackerman steering", and "the long idler arm". This long, (FAST RATIO) pitman arm we offer is basically the same arm used on the AAR's and T/A's. The stock T/A set-up = long (FAST RATIO) pitman arm and a short (stock length) idler arm. We heard that screws up the Ackerman steering. So we put a car on turning plates to test that, and find out. Turning plates or toe plates lay underneath the front tires and read turning angle for each tire independently as you turn the steering wheel. Ackerman steering, means that as you turn the steering wheel, the inside tire turns about 3 or 4 degrees more than the outside tire so both tires are arching equally, giving you, ~ "zero scrub". We tested this in 3 different modes;....1, short pitman , short idler,(ie. Your car, stock)....2, long pitman , short idler,(ie. T/A, AAR stock).... 3, long pitman , long idler,(recommended). RESULTS: 1) short/short = OK ackerman thru out sweep....2)long/long = OK Ackerman thru out sweep....3)long/short = OK ackerman thru right hand sweep and OK ackerman up to about 20 degrees left. From ~20 degrees on out , the Ackerman gets exaggerated to ~10-12 degrees. We don't think this really adds up to very much in your overall performance driving picture, because 20 degrees is a pretty tight turn , more like a parking maneuver than anything else. But.... why not get it as good as you can get it .Conclusion; If you can ..., use the long idler.
