Rack kit - consists of new Flaming River custom width rack and pinion, billet rack mount,
steering adapter u-joint, rack and pinion u-joint, steering shaft, and outer
tie rod bump steer kit - NOTE: this kit only works with BMR
K-members.
BMR started from a clean slate when they
developed their manual rack conversion kit. The industry standard has long been
to use the Pinto-style rack and pinion when manual steering is required. They
are rugged, lightweight and very compact. The aftermarket has installed them on
practically every car out there and a lot of them work just fine. What most
people don't understand is that one rack doesn't fit all regardless of what
people tell you. A Pinto rack installed on a fourth generation F-car will create
excessive bump-steer unless measures are taken to correct the problem. The
overall distance between the inner tie rod pivot points should match the
overall distance between the A-arm pivot points. Any variation to this will
cause the tie rods and A-arms to swing on two seperate arcs. This means the
vehicles toe will change as the suspension travels up and down, otherwise known
as bump steer.
The fourth generation F-body A-arms pivot
from a width that is 2 inches wider than the inner tie rod pivot points of a
Pinto-style rack and pinion. To compensate for this, BMR provides a custom
width rack just for this application. Another benefit to designing from the
ground up is that the rack extension has been biased to the passenger side of
the vehicle. By doing so, the steering shaft is relocated an additional inch to
the drivers side allowing much improved header clearance. With this kit you can
use up to 2" primary tube headers without modification!
Other components in the kit include Flaming Rivers'
billet, bearing-style u-joints custom sized to the OE steering shaft, billet
rack mount adapter and double-threaded tie rod ends. We use QA1 XR series rod
ends and CNC machined bump spacers. This is a straight forward bolt-in
installation requiring no fabrication or welding. All mounting hardware and
installation instructions included.
