Pinion Valve Tech |
| Fox Body Mustangs had
rather small torsion bars from the factory ranging from
.195 to a rare .215. Our normal .230 rack is quite a
step up in road feel and will give you a modern sports
car feel.
If you want a really
heavy feel the AGR Cobra R Rack utilizes .245 bar
valving in a “bolt in” mustang rack.
A special heavy
torsion bar is used in the pinion valve of a mustang
type rack and pinion.
The torsion bar in
the pinion valve controls the flow of hydraulic assist.
It is a type of
spring, as with all springs both ends must be held in
order for it to engage. The thickness of the spring
shank determines how much force must be applied to open
as well as how much it opens. Essentially one end is
connected to the pinion gear which is in turn connected
through the rack shaft to your tires. The other end is
connected through your steering shaft to the steering
wheel. In review the torsion bar senses the input at the
steering wheel versus the load on the tires and delivers
the hydraulic assist. A light torsion bar will open
easily and quickly resulting in twitchy steering
especially at highway speeds and above.
A heavy bar will be
more of a gradual, controlled opening letting the driver
feel the road and the road feel the driver. |
