1.0 Power Steering Cooler Capacity and Weight & Oil Requirements

The added capacity of the cooler is:
.85 liters
29 oz.
This system MUST use high grade pure synthetic. Do not use ATF.
Did you know there are five grades of oil and high grade synthetic is water clear (sometimes companies add a color for marketing)?
Why the good stuff?
High grade synthetics offer a much higher temperature capacity without breaking down. Even more important is that it will maintain a core consistent viscosity at low temperatures so the steering will not become heavy and blow off the pressure relief valve to soon. This could cause a large reduction in power assist at very low temperature conditions (sub 10F).
It’s a 150% increase in capacity
Oil used should be to Chrysler minimum spec MS-11655
All oils that meet this spec may be used.

What length RPV should I order for my wheels?

You will need to measure your valve stem well in order to properly determine which length valve to purchase. It is impossible for us to know the length for every wheel application on the market as wheel width, offset, size often changes the depth of the valve stem well. Please CLICK HERE to watch a video that demonstrates how to properly measure.

What length autoLYNX do I purchase for a 2"-2.5" lift?

The 2" - 2.5" lift is right between the 8" and 10.5" autoLYNX size. The determining factor is your front bump-stop length and shock stroke length. If you have at least a 2" bump-stop extension installed in the front, you can/should run the 10.5" version. If you do not have bump-stop extension installed in the front you will need to run the 8" version. 2" bump-stop extensions are common with most lifts that include a 10" or greater travel shock.

8" autoLYNX works w/ 7" - 9.5" travel shocks and no added bump-stops.

10.5" autoLYNX works w/ 9.5" - 13" travel shocks w/ at least 2" front bump-stop extension.
