NEW Cruiser buggy - Sunray Engineering

[Radd Cruisers]

Kinda cool watching build this rig, when you see them building the axle housing and mouting the 4 link mounts without being under the truck shows you how much engineering has gone into this thing.

Must be fun to have really cool CAD programs and a engeering degree to boot.

Nice work..........

Nothing is on a computer on this rig.

Tom has made drawing of every angle of the build.

He is an amazing guy.

Tolstoy on the shelf....

rear axle placement time....

[wngrog]

I put the first scratch on it last night when I hit it with my tow rig while pulling in the shop

That truck has more cool little features that no one will ever see!!!

[peesalot]

so who gets to sit with their nut sack right on top of the front output ? Is that third the high pinion bling like yours ? The .090 wall tube won't fold on impact points ? I hate you rich fawkers . Poor ole 40 looks lame compared to this stuff.

I will ride with my sack over the output...no sweat

That third has more bling than mine....mine is just a standard 3rd that is upside-down with a bad ass one-off oiler that Sunray designed.

.090 Crome Moly will take it. Tough shit.

more buggy porn...

[woody]

two more...these are the ends for all the suspension links....

[woody]

and lastly, a little bling courtesy of PSC Powersteering....

[Rock Taxi]

Ok, gun drilled twisties and turned down threaded inserts for them are super bling.

Jim, you are seriously at risk of your rig being better looking than you.

Ed

[Radd Cruisers]

So the design behind the twisty is threads????

[orangefj45]

can you post a pic of a complete "link" or "joint" or whatever you call that dealio?

bad-ass so far, that's for sure. i love watching the buildup threads, spawns lotsa ideas.

[Rock Taxi]

Here is one of Nolen's, not turned down and gun drilled, but the same basic parts.

don't mean to hijack the thread, ah, what the hell, let's do it anyways.
what would the pros and cons of these "joints" be versus say a johnny joint or a heim end?

[wngrog]

The bling on Sunray's twistys is not the threads, it is the piece that the threads insert into and twist. They are machined with an O ring on each end so they keep grease in and crap out.

That is just some of the weight savings stuff Tom has executed on this rig. I can't wait for you guys to see it all.....

Another nice feature with the Sunray twisty is the rubber insert......It allows for a close tolerance fit and no play in the joint....the rubber compound is specificly engineered for this use and holds up well to trail use.

and Ed, that hurt!

Johnny's are known to wear out and get sloppy. Heims are nice if you pay for the high quality ones and replace them when they wear out.

Cons are Heims are metal-on-metal and the "twistys" use rubber XJ bushings which take up some of the shock your control arms get, extending the life of the control arm.

Also, there is 360* of movement in the Twisty, unlike the Johnny Joint.

[orangefj45]

hijack almost over, i promise. what sizes do the twisties come in and how much are they?

[wngrog]

Email Lance at Sunray at lanzg@yahoo.com

One size.....mine fit 1.75" links or larger

Bushings are from an XJ.

[woody]

couple pics of the rearlinks in process....and yes, these WILL be in double shear once completed....

[Mace]

Curious...
So the twisties use threads to allow movement correct?

Any concerns with the threads wearing out prematurely???

I have heard of people having issues because the heims did not have the locknuts tightened properly..

No, the threads on these are monstrous. I know these twisties have been on the Red TJ that the owner of the buggy in the thread drives for 4-5 years of hard wheeling.

Right on.

These links work different than hiems in that you would usually have hiems at each end of the link and you would want to lock the hiem shaft to the link, with lock nuts, so as to maintain their original setting. The axle movement and articulation is absorbed in the hiems.

In the use of the twisty, you use a twisty on the link end at the frame attachment point. The other end of the link has a welded fitting that has the eccentric cut (bling, weight, bling), the link is fixed in place by its mount to the axle, but still can still move in its mount. The twisty is fixed in place by its mount to the frame, but can also move in its mount. The link and the twisty do there work as the axle articulates.

Lance, am I anywhere near correct with that explanation?

You do not have to have a haim at each end of the link..

I use heims at one end and RE Joints at the other.

Imagine this. poly bushings at the axle end.. Heims at the frame end without locknuts. pretty similar to the twistie setup right??
Basically solid mount at the frame and the axle end with most of the rotational capabilities taken up by the threads on the twistie or by the heim...

Or am I way off Base???

[Jimbro]

Mace,

What you are discribing is similiar in action but completely dis-similiar in materials....but should work, couldn't guess for how long.

The twistys have been like the bunny, they just keep going............

Jimbro

[wngrog]

Another adavantage of a twisty using the XJ bushings at both ends of the link is the rubber in the bushings absorb lots of shock making links last longer under abuse without bending.
