Rack and pinion order options

Postby 90LSC » Sun Dec 18, 2016 3:45 pm

So when I go to order a new rack and pinion unit it ask if I have a performance suspension or not. So first how do I figure out which mine has.

Since you have a LSC you have the Sport Steering. 1 3/4 turns lock to lock.

Since I own both a Blass and two LSC's, let me elaborate and answer this question from my personal experience.

The Blass is equipped with a steering rack with a gear ratio that allows three complete turns of the steering wheel full left turn lock to full right turn lock and vice versa. Steering effort and road feel are minimal with this rack. This is considered the standard suspension.

The LSC is equipped with a steering rack with a gear ratio that allows two and a half complete turns of the steering wheel full left turn lock to full right turn lock and vice versa. Steering effort and road feel are greater with this rack. This is considered the performance suspension.

I've got a 1984 Base Model and a 1990 Bill Blass... I recently acquired a lot of parts from a 1988 LSC, including a complete rack and pinon assembly. My question is, will it fit either or both my cars?

I don't believe the LSC rack is compatible with 90 and earlier BB or Base models. It is a different ratio. :)

I don't understand why both types of steering racks should not be interchangeable.
Isn't the ratio be made within the steering rack?

I'm sure you can swap them, the ratio will be the main difference. Later Mustangs can also but those require other part to make them work, plus many of those are made for wider wheel/tires, so their bump stops are going to make turning wider than ever.

Try to find only lower mileage original racks, from Mark VII's. Avoid rebuilt racks if at all possible.
