So I was doing a lot of reading last night, trying to figure this out. I have the Enduro long arms, so they are using short upper arms and long lower arms as a hybrid setup. Honestly, until last night, I didn't understand the problems associated with this set up. As I have been researching this more, I am realizing this is why my joints are failing so quickly - this set up puts a lot of tension on those upper joints. I think I am going to bite the bullet and convert the rear to the Pro upper long arms — as I already chewed up a 4 month old rear sway bar bushing.
On the front, I am pretty sure that the correct swap for the Enduro upper shorts in the front is the Duroflex Product ID 7051. I will see how they workout. I'd rather not have to do the conversion up front too, as both require some welding that I cannot do... so that means $$$$
