arms with swivel links or johnny joints?

[chevelletiger]

I want to see what everybody thinks what would work best in a four link.swivel links or j.j.? And not just biased reviews saying "because dse makes them and wins alot of racing events" or "j.j. Because they kick ass in off road racing ect." real hard tech.and if there really needed in autocross racing,i have noticed ride tech doent use these type of moving ends.phil

None of them perform any better than the other. The point of the other joints is longevity over the standard heim joint. Spohn Racing makes one better than the j.j. and quite possibly the longest lasing joint on the market at this time. They are rebuildable as well

I used Currie's joints, for a few reasons.

1, they are rebuildable, 2, they were very beefy and C, they will free up the suspension during roll to prevent binding, whiich is an issue with solid poly ends.

What are the swivel links you are talking about? I've been trying to decide what joints I want for the three link I'm going to build. I knew about JJs, and recently saw UMI had their Roto-Joints which can be tightened as they wear. I forgot Spohn had their Del-Spheres. The Spohn and UMI joints look similar and I like they can be tightened. They both use delrin inserts where it looks like the JJs use poly and are rebuildable but can't be tightened. I was leaning toward the UMI joints but seeing that the Spohns are cheaper maybe I'll give those a try.

I have a set of UMI Roto-Joints. I have not installed them yet, but they look fantastic. I went with them over Spohn because of their one piece ball design. They are a bit on the heavy side, but I bet the link will bend before I have issues with them.

I think the Johny Joints will be less harsh on the street, as there is more "cushioning" in them. The other brands that use i little bit of "delrin" ect. In a rod end are more to prevent metal-on-metal wear, they dont take much shock out of the system. The DSE "swive-link" probably offers the least articulation compared to the others. So my opinion is: Johny-Joint>Spohn/UMI>DSE

Used the spohn units on my 69 Camaro on the rear trailing arms. Thought they were great and will use them again on my next project...and they are plenty beefy.

Thanks guys.it sucks thou i was going to do will call on the j.j. And the sales guy said they moved from anaheim to corona

I'll be the oddball and vote for the DSE swivel links for one reason....rubber bushed.

Donny,it did make some arms with a swivel link style end(i saw there patent drawing online and machined my own shafts and bronze bushings)with rubber bushings on each end,but most people didnt think they articulated enough to have any gain so im going to make arms with johnny joints.i still have arms on car though.phil

[UMI Performance]

One very nice thing about the UMI Roto-Joint is we build the entire joint here in our facility, every piece of that joint is machined right here. Unlike our competitors that out source their housings and one competitor that outsources the entire assembly. The in-house manufacturing helps us control our quality and make quick changes or fixes if ever necessary. It also supports the USA and not overseas companies... as for pricing, we are a little more than one competitor and this is because this is a USA built joint and we are sure theirs are overseas.

Our Roto-Joint is rebuild-able and can be tightened if it wears, for ride sensitive drivers look at our Roto-Joint/Poly bushing combination control arms.
