Orbital (Steering Control Valve)
All of Trail-Gear’s orbitals (steering
control valves) have a built in
return-to-center function. This means
that when the driver releases the wheel
the tires will automatically return to
the center position. This is a
convenient feature that allows for slow
rock crawling or driving at higher
speeds. The amount of turns it takes to
get from lock to lock will depend on
what ram you combine with your orbital.
We have included a chart that will tell
you exactly how many turns it will take
to get from lock to lock with the
different orbital/ram combinations, with
the recommended combinations in bold
blue letters.

Rock Assault™
Double Ended Ram and Clevis Kits

Through
years of research, development, and
testing we at Trail-Gear have
developed our double ended ram to
meet the tough demands of top level
rock crawling competitors and the
toughest trails in the world. Based
on our experience we knew exactly
what we wanted in a ram, and what we
didn't.
Most
rams on the market only have one rod
seal. We started with the
primary and secondary rod seal to
insure that fluid leakage would
never be an issue. We also
included two wiper seals in our
design to make sure that dirt and
debris stay on the trail and don't
get into your steering system. In
addition, we designed our ram with a
Triple Lip Piston Seal for
consistent steering with no drift or
fluid bypassing the piston.
In
true Trail-Gear style we also had to
make our ram the strongest on the
market, so we added a feature that
you will not see on any other ram on
the market. We designed ours
with a piston wear band and a rod
bushing. The bushing allows
the rod to absorb much higher side
loads. We also machined our
piston shaft out of a single piece
of 4340 chromoly. Other rams
on the market use a two-piece
welded or threaded piston shaft that
can fail under severe loads.
Our Double Ended Ram and Clevis Kits
have a 6", 8", or 10" stroke x 2.25"
bore x 1.125” rod. The
cylinder has a black zinc-plate
finish while the rod has
3/4x16 female threads on each end
and is made entirely out of 4340
chromoly material.
The 6 inch ram and clevis kit has 6
total inches of travel and is
perfect for Toyota's and narrowed
Dana 44's.
The 8 inch ram and clevis kit has 8
total inches of travel and was made
to work with Dana 44's and custom
length Dana 60 applications.
The 10 inch ram and clevis kit has
10 total inches of travel and is
used for buggies and comp rigs with
up to 45 degree steering radius.

Reservoir
Filter
Kit
When you have
invested thousands of dollars into your full
hydraulic steering system, you will want to
protect it with the best reservoir and
filter that you can get. That is why
Trail-Gear has developed our new Rock
Assault™ Reservoir. It is not only heavy
duty, but also compact and user friendly. It
features a full size hydraulic oil filer
that will keep all the bad stuff out of your
power steering pump and hydraulic ram. Our
Rock Assault™ Reservoir also comes with an
internal baffle, features two internal
magnets, and is completely sealed with top
quality o-rings to prevent any fluid
leakage. This reservoir also has a quick
drain plug that is located at the bottom of
the unit that will allow you to easily drain
your system in minutes. Our unique fluid
flow design is rated up to 15GPM and allows
you to use your steering system while the
truck is on its side or at other unusual
angles that it might incur during rock
crawling or desert racing.

Note:
Do not fill more than 1/2" above the
internal baffle. |

Double Ended Ram Mounting Kit
This kit
will take almost all the fabrication
work out of mounting your Rock Assault™
Double Ended Ram and Clevis Kit to
almost any axle housing. The main
support tube is 1.5" diameter, .120"
wall, 1035 DOM, comes pre-bent, and can be
trimmed to size and coped on the ends
for a custom fit. The formed mounting
plates are not welded to the tube so you
can move them to the left or right to
center the ram on the axle. We include a
support tube, but on certain axles
additional gussets may be required.
Product is shipped unpainted.

Tie
Rod Kit
Trail-Gear has made the perfect kit
for building tie rod links for use
with a double-ended ram. Based on
our testing and experience with kits
like these, we know that the failure
point is always in the tie rod ends,
which is why Trail-Gear uses only
our own brand of Chromo Rod Ends.
The main body of each rod end is
100% 4340 chromoly, and the ball of
each rod end is made out of AISI
52100 material and then hard
chrome-plated for an extremely tough
finish. We also added tie rod
tubing that is 100% seamless DOM,
and to top it off the weld in bungs
are machined out of solid billet.
With these components in place we
feel that this kit is so strong it
stands apart from every other kit on
the market.
This kit is also perfect match for
our Rock Assault™ Double Ended Ram
and Clevis Kits.

Rock-AssaultTM
Ram Steering
The Rock-AssaultTM
Ram Steering assist kit is the best kit you
will find anywhere! Our Toyota kit features
a 6" X 1.5" stroke hydraulic ram with high
temp inner and outer seals for long life and
no leaks. Our specially designed ram
features a 3/4" rod that is 50% stronger
than other 1/2" rods on the market. For Dana
knuckle applications we also offer an 8"
stroke version.
Our specially
formed, easy to install brackets make
installing our kit a breeze. If you have
looked at other kits on the market, you will
see they either don't include mounts or they
just provide generic tabs. Our mounting
hardware is specially designed to fit the
Toyota axle and High Steer. Once the
steering box has been tapped, installation
of the ram takes about one hour. Each
bracket is formed from heavy-duty 1/4" plate
steel for extra strength. Fits 1979 - 1995
Toyota Pickup and 4Runner with solid front
axle.
Included with
each ram kit:
- Ram with
high temp inner and outer seals

Application
Notes:
If you
purchase a tapped steering box from
Trail-Gear, the box will include two, 1/4"
pipe to JIC fittings on the box. If you will
be tapping your own steering box, you will
need to purchase a pair of 1/4" to JIC #6
fittings for the steering box. The
Trail-Gear part number for this fitting is
130263-1 and they can be purchased
here.
Adding a ram
assist steering to a truck with the stock
power steering pump will slow the steering
noticeably. While it will take less steering
wheel effort to turn the wheels, but it will
take a little longer time to to turn the
wheels, especially at low engine rpm's. The
larger the ram bore then more noticeable the
slowness becomes. If you are planning to use
the stock Toyota power steering pump we
recommend using the 1.5" ram. We strongly
recommend using a high volume/pressure "TC"
style pump when using 2" bore rams. On
V6 applications, the oil pan may need to be
modified or replaced to make room for the
ram.
