EXCELLENT refurbished leveling valve as shown. This one is the best we have seen in the last 10 years. Never been subject to road salt. It is super clean inside with hardly any scratches.  Kent has taken this apart in his shop, cleaned it, and inspected it. All new seals installed. You will receive his video on how to adjust it once installed on the car and a flag pin to complete the adjustment.  He also recommends having his special toolset to ensure you don't lose your mind while attempting to remove the rod and tighten the locking nuts. See related products below.

Early SLS Self Leveling Valve Adjustment Procedures - On Demand Video

Product Details

PLEASE NOTE:  On some valves, the outside fittings vary. You can install the fittings from your current pump if need be.

When you receive the rebuilt leveling valve here are some tips and precautions.
 
Be very careful when handling so no dirt particles will enter the unit and be SUPER CAREFUL when installing the threaded end of each hardline so you do not cross-thread. Run the fitting in two or three full turns by hand before you ever put a wrench to them. You may need to take some of your fitting adapters off your old valve and install them on the new valve before mounting them in your car.
 
Follow the video instructions adjust after installation.

SLS Leveling Adjustment - Special Tool Set for Adjusting Ride Height

Adjustment can be done with regular wrenches, but when you are doing it under the car with engine running your words will not be kind.

Why these special tools? Can't you just adjust that rod with a couple of combination open end wrenches. Maybe yes and no... have you tried it?  You can not get the rod off with a regular thickness 10 mm open end wrench.

Dont neglect this service as many do! I recommend the hydraulic fluid and filter be changed every 30,000 miles. You would not believe how many SLS vehicles I have seen with dirty hydraulic fluid - I mean nasty!  Sometimes I have even found engine oil in the system!
