Power Steering Kit
(Rock Assault)
After you have completed the solid axle swap on your 95-04 Tacoma, you will need to upgrade your power steering pump so that you can turn those big tires on the trail. The stock pump works well enough for the stock IFS and stock tires, but once you put on larger tires the pump will not be able to put out enough volume to turn them fast enough, especially if you have a ram assist system installed.
Trail-Gear has developed power steering upgrade kits for the 2.7L and the 3.4L Tacoma that include all the brackets, hoses, and hardware that you will need to do the install right the first time. Each kit includes an all steel TC style pump. The pump in the 2.7L kit puts out 4 GPM of flow at 1,450 PSI of pressure. The pump in the 3.4L kit puts out 4.5 GPM of flow at 1,650 PSI of pressure. The higher output offered by these pumps will improve your steering capabilities and allow you to take on the extreme off road trails that solid axle Tacoma's are known for frequenting.
Recommended only with RAM ASSIST or Full Hydro systems. If using without RAM ASSIST, this may fatigue your Steering Box!
NOTE: This kit is not designed for use with stock steering rack. Use with hydro assist or full Hydro steering applications only.
This product should not be used in a manner that violates Federal EPA Laws.

25. Fill radiator.
26. Fill the power steering system with synthetic power steering fluid. We recommend Royal Purple full synthetic fluid.
When filling the reservoir, do not fill to the top, allow about 1/2" for fluid expansion due to heat. It will take some time
to fully bleed the system the first time. With the vehicle on jack stands and tires completely off the ground, engine not
running, turn the steering wheel from lock to lock several times and then refill the power steering reservoir with fluid.
Note, this is done so that the power steering pump does not get started dry, which can cause damage to the pump.
Now you’re ready to start the engine and turn the steering wheel from lock to lock, we recommend that you run the
motor for about 5 minutes at a time during the bleeding. Allow the oil to set until all the bubbles have separated out
of the oil, then run the motor again for 5 minutes. Repeat this procedure until the oil runs without foam or bubbles.
