Limit straps.

[Antman]

I thought I would show you all a picture of what I finally did for limiting the
unloading of the front of my TJ. Worked good in Moab! Except I might take even more slack out of them.:D

I got the three tabs and two 18" straps at 4 Wheelers.

Uhhh, looks like your UCA fell off!!!! ;)

Rock Krawler doesn't use the passenger side upper control arm. :D

They use full length on drivers side upper and lower and just lower on right side.

4 link front and rear.:)

Actually I took it off to see if anyone would notice.:rolleyes:

Also check out the 200,000 mile + 4L motor.:)

I have been running the same set up for a while now. My upper tabs are in a different location than yours but have had no problems.
I also run a single on the rear.

Front.

Rear.

Shock locations are experimental. So far, so good.

Help a newbie out - what does that do?

limits your flex. from what i understand it limits your flex so you dont lose your springs but im sure there are other reasons for them and someone else will inform you of them.

If you're a newbie you probably have short arms. Typically you won't have to begin to think about limiting straps until you get to long arms. This is due to long arms allowing considerably more droop than short arms (more droop equals losing springs like Glen said... but can also allow the suspension to unload more when climbing, damage drivelines, etc).

I thought limiting straps also helped releive stress from the shocks to not having to limit travel, from what I understand they are more effective on the extremeties of the axle.....?

That too. In fact breaking axle cross pins is very common hence bar pin eliminators. After all, I had it happen to me. The below pic happened after my bar pin broke and the shock could no longer limit travel. This was the first trip out on this driveshaft and with my rear tire almost under the drivers door my driveshaft wasn't very happy:

Not really. It has zero to do with losing springs as a primary motivation for doing this.

Center limit straps limit total axle DROOP -- totally different. Flex could be limited by placing the straps at the ENDS of the axle outboard enar the wheels. Center limits straps really do not limit articulation (flex) in any significant way although they can limit it somewhat depending on how they are set up.

Very little droop is required by a rock crawler. Limiting total axle droop keeps weight on the axle where it is supposed to be. This helps to keep the springs under tension and keeps them from unloading at inopportune times, like when you're climbing or articulating. The weight remains more on the front axle during a climb which is where it is required.

Limit straps can be used to keep coil springs in their buckets by some, but that is not what is going on here. The center strap when properly installed can be made to sufficiently limit articulation also, which may keep the coil springs in place.

A way to keep the springs in place is to retain the bottom (at least) with a clip, and use bump stop extensions at the top. This limits upward flex (stuff) and will also keep the spring headed towards the bucket when it settles back in. One may still require outboard limit straps if there is too much articulation for the system, but with the RK kit a great number of us have found the center strap and the bump stops and clips to be sufficient.

A single one in the rear like Renob's works great for the same reasons as above. Reduces unloading and keeps the weight better distributed at the right times. Again, zero to do with spring retention, that's handled differently in the back for these coil sprung things.

BINGO Barry. :)

As XFALLEN mentioned, the set up that ANTMAN and RENOB posted is mainly to keep the chassis from walking away from the axle during steep climbs. Un-loading so to speak, big problem with long travel suspensions.

[Antman]

Right on Barry and Geno! Renob too. I am sitting in Sky Harbor, heading to
Salem for the week. Hope it's cool up there!:rolleyes:

[Renob]

If you want to keep your rear springs from falling out while at full drop, just install the same spring retainers discs that you see here.

I got the idea from Stu's site and took it a step further by fabricating a set for the top as well and locating them at the bottom of my bump stop extensions.

I believe for most applications, lowers plates only will be sufficient.

I have yet to loose a spring with this set up.

Quick question off topic though. Why mount your shocks so far inward to center?

WalterI moved them inboard and up on the axle and cross member.

I did this to achieve more ground clearance and articulation without having to change to longer shocks which would limit my wheels, up travel.

So far this has worked fine but as you know, only time & trails will tell.

I am gonna be installinlimit straps on my rig. I got revolver shackles installed so I figure it would be wise to install them in the center in the rear. but for the front should I install it in the center as well?
