Understand with the older style XR there are stops required in the rams to restrict lift. That they are not required for the newer XR when attaching to a Bravo 1.

Can anyone identify this unit for me as to wethter or not the stops are required?

Believe this to be a 2000 year model.

Just me but, cant you use the serial number off the upper to look up what year it is???

Only if the tags are original... one of my xr's peeled its tags and I put new ones on.. blank...

I can't answer your spacer question, but the older XR u-joints have grease zerks like your picture shows. The new XR u-joints are sealed and do not have zerks.

That's what I was looking for. Was informed stops are required for older style and they hav zerks. Was looking for verification this was older style. Thanks.

Glad I could help!
