OffRoad Design Dana 60 Hi-steer kit
With the addition of a hydro Assist steering System we
really wanted to locate the hydraulic ram higher up in the steering system
as well as relocate the tie-rod above the leaf springs to help keep them off the rocks. We were very happy
with our current OffRoad Design cross over steering arm so when we heard
that they were starting to produce a hi-steer version it was a no brainer
to make the call and pick up the rest of the parts we needed.
OffRoad Design's new hi-steer arm (drivers side) is made
with the same quality and attention to detail as their standard cross over
steering arm (passenger side). In fact it is meant to work with their
existing non hi-steer kit as an add-on if you already have their standard
cross-over, this saves the hassle and expense of having to buy two new
arms when switching from a standard to a hi-steer setup. For those of you
that have an older version of ORD's standard cross-over arm with out the
extra tie rod hole, a discount is offered from ORD to ease the transition
to their new arms.
The ORD hi-steer kit consists of a drop pitman arm,
two
new beefy steering arms accounting for the king pin axis inclination angle, a new thick wall DOM drag link
and tie-rod
with rod ends, and all the necessary nuts and bolts. ORD will also sell
any of the parts separately to complete your own system.
Steering arm Features:
Milled from 1020 cold rolled steel.
Arms attached using
stock Dana steering arm studs providing a precision fit.
Proper tapered nuts included.
Kingpin bushing cap is welded to arm providing a one piece
unit.
Machined with the proper axis inclination to prevent
binding during articulation.
Arms are drilled with
an extra bolt hole to bolt on Dedenbear HD knuckles.
Tierod hole is offset to the outside to gain additional ackerman angle.
Hi-steer cross-over VS standard cross-over
Many
people ask "What's the difference between hi-steer and standard
cross-over steering", the main advantage to running hi-steer is that the tie-rod
gets relocated to the top of the new steering arms above the leaf springs
keeping it out of those pesky rocks everyone loves so much. Hi-steer
requires and additional steering arm located on the drivers side so that
the tie rod has a connection point on both sides of the axle. We run a
hydro assist steering ram connected to the tie rod that also gets relocated
up higher in the steering system, it will last much longer located out of
harms way.

If you are
running a 4"-5" lift with the axle moved forward an inch or more
this setup may not work for you due to pitman arm tie rod clearance
issues. There are also other factors that could affect pitman arm to tie
rod contact, like the spring arch causing the axle to move back under
compression, there is only so much room above the springs and not a lot of
space to work with.

Moving the tie rod to the tops of the knuckles especially
when running hydro assist steering will put more stress on the knuckles,
they can take a fair amount of punishment but could break with very large
tires, lots of horse power and a heavy foot but it is rare. If you fit
that category or "actually have" broken a knuckle you can
upgrade your factory ones to Dedenbear's ultra stout knuckles for the
ultimate in beef, in fact the ORD steering arms are also designed to work
with their 5 stud mounting setup. Because the tie rod is
closer to the kingpin centerline in the "high" position than it
was in the stock location, it has a lot more stress on it and this will
shorten the life of the ends to some extent. Also, any looseness in the
ends will translate into more wobble at the wheel. So if you don't
actually need the clearance, a HD tie rod in the stock location will give
a bit better service life and cost less.
Installation
Installing the hi-steer arms is basically the same as installing
ORD's standard cross-over steering arm kit but with the addition of the extra drivers side arm and of course
moving the tie rod from the factory position up to the steering arms. An
extra set of factory studs for mounting the drivers side arm will be
needed from either ORD or your local GM dealership. If you are going from
factory steering to hi-steer then the new studs can be used on the
passenger side (studs are used from the factory on the drivers side).

OffRoad Design can
either supply a complete kit or any individual part that you may need.
Before you bolt the steering arms down be sure to check the condition of
your springs and bushings, ORD can also supply a king pin spring and bushing kit in the event yours
need to be replaced.
The test bed for this install is a 1990 K5 with 4" of
suspension lift and the axle located in the stock position, this is
important due to the close proximity of the pitman arm in relation to the
tie rod, with our setup they are very close but do not rub.
Installing cross over steering with a Dana 60 axle is completely
bolt on and can be done in a driveway or home garage with most common
tools although a stud remover and a few clamps could come in quite handy.
The first thing you will want to do is park on level ground and pull the
front tires to gain access to the steering components.
If you are installing a crossover steering kit for the
first time and have the factory steering setup you will need to change
from a 4x4 steering box to a 2x4 steering box because the stock
steering gear turns the pitman arm from front to back, while the two wheel
version will rotate the pitman arm from left to right, another option is to swap out the steering sector shaft
from your old box and replace it with a new 2x4 unit. The "UAV"
has been running ORD's standard configuration cross over for quite a while
now so it already had the 2x4 steering box so we were good to go.
We removed the drivers side king pin cap and cleaned the knuckle
surface (the area under the steering arm), we had to use a stud
remover to coax a couple of the cap studs out that were being stubborn,
otherwise everything came of fairly easy.

Sometimes the springs that are used to keep pressure on
the king pins will not allow the new steering arm to seat properly on to
the knuckle which was in our case. We simply used two clamps to force the
arm downward enough to get the four bolts started then tightened them down
the rest of the way. At this point the pitman arm can be installed onto
the steering box shaft (not necessary if you already had standard
configuration cross over), be sure to have the steering wheel centered when
you do this.
If you have the factory steering setup you will need to
install the drag link and is what will
tie the entire steering system together connecting the passenger side steering arm with
the pitman arm. This is the step where a little adjustment comes in to
play, the drag link ends will need to be rotated in or out to get proper
lock to lock steering, make sure to center the steering wheel at this time
also.
We already
were running cross-over steering with a beefy tie-rod in the factory low
position so it had to be shortened before it could be installed on top of
the steering arms, this is due in part to the design of the knuckles being
angled in at the top.

Summary
After running the hi-steer setup for almost a full season now
with no problems whatsoever we totally recommend it to anyone who likes to
play in the big rocks. Steering arm geometry is optimized for best turning radius, minimum tie rod stress
and maximum arm bending strength, truly a well thought out kit.
One thing we wanted to note here, if you currently have
ORD hi-steer arms with the older 4 holes and want to run the much stronger
than stock Dedenbear knuckles, OffRoad Design can drill the extra hole
needed for you. On our test K5 everything fit perfectly
although very tight, we were very impressed by the quality and the fact
that ORD makes everything needed for this setup not just the arms
themselves. - Steve

Update: OffRoad Design is working on a super high
strength ARP steering arm stud kit as a better quality, less expensive
alternative to the GM studs, please call ORD for up to date pricing
information.
