Please forgive me for asking what may be a "newbie" type question but...what is the purpose of a "wristed" radius arm?

I've seen extended radius arms and even heim-jointed radius arms, but this is the first I've ever seen a "wristed" radius arm before today.

Yep, it's bolt on flex. If you build your own it probably costs less than $20. Do a search on google or something and you'll find a lot of info. I need to get my butt in gear and do mine. I figure it will take about a day.

This is one of the best reasons to drop a EB 44 in your broncoII.

Maybe we should have a gear swap party. We can race! Still haven't called Quinn, but I was thinkin about it yesterday. I am picking up a few new fenders(better than mine) next week and I'm going to start scabbing on that EB grill you gave me.

Smurfsdad, thanks for the link... I think I need to get my a$$ in gear, and get a second set of arms to play with. Who did your machine work?? If you did it yourself, wanna do me some too.. I think that is the only thing that I wouln't have a clue how to do, or have the equipment to do it..

Nobody.... are those EB springs in the front of those BII's, if so, how is the ride, I am still having mixed feeling about all coils, and everyone is shooting down my ideas, but not giving me any new one's. All I know for sure is that my springs suck!!!!!!!!

Both those trucks are not mine. The camo one is FearMe on this board. They are both BII bodys on EB frames.

I on the otherhand have a BII with 302/ D44/NP435/D20. Basically all EB stuff. I used the Duff 3.5" EB coils. They work absolutely great. Very soft, and they flex very well. The wildhorses 5.5" coils are supposed to be good as well. I might actually try them some day when I get around to changing the coil buckets. The Duff coils cost me $115 for the pair. It just doesnt' get any better than that.

I can assure you that you will be perfectly happy with the duff coils.

I built mine you do not need any machine work I used bolts to hinge and pin. All you have to have is a sawzall to cut the arm ant material and a welder ( not a 110v ) and a drill some time and patients. I am not saying a sawzall and drill are the best way but I do not have a plasma cutter or a drill press. I have heard plenty of people say that they would not trust a bolt for the hinge but I have seen plenty that do it and never a problem I would go grade 8 and put in a grease fitting.
1uglyranger you said you need to get another set you do understand that only 1 arm gets wristed and the other stays stock?

not really but its more common and a better idea to do the Passenger side

if you did both nothing would hold the axel from floating all over and that would be trouble.

Why you only need to wrist 1 arm:

When 1 side is compressed, the axle rotates backwards into the rear of the front fender. When the other side is drooping, the axle rotates forwards towards the front of the front fender. This creates bind that the C-bushings must take up and limits flex. Wristing 1 arms allows the R side to either rotate forward or backward to match the L side when flexing.

ps. With a 4 link, this is not an issue.

Question for everyone: Where do you mount the shock on the wristed arm? In front or behind the pivot and did you use the same stock shock mount?

You only wrist one arm, cuz the other is needed to stop the axle from spinning. Besides, as shown above, 1 gets the job done just fine!

One un-jointed radius arm is needed to control the caster angles.

Since the drive shaft is close to, and nearly paralell to the drivers-side radius arm, keeping that one stock keeps the pinion pointing at the transfer case, more or less,
and at more-or-less equal distance. Only the rear U-joint (T-case end) sees high angles.

If you wristed only the driver's side, the front U-joint would also have to be a high angle type, and you'd need a lot more slip range in the shaft.

the passenger side is the best to put it on, otherwise the driveshaft is probably going to bind up. If you are going to make a home-brew'd arm with a bolt I would suggest going as big of a diameter as you can get in there, I would also suggest a grade 5, not grade 8 - the grade 5 is more ductile and therefore is better in shear loading, also it will show signs of impending failure, where a grade 8 will just shear off. I don't know about you, but losing a radius arm at 75mph on the highway isn't highon my list on of "must do's". Another suggestion would be to use a brass or oillite bushing so you don't wear the bolt.
