Limiting strap

[old_man]

I just finished fabing my HP44 radius arm. I'm interested in how any of you guys rigged a limiting strap on various front axles. I've got a few ideas, but would appreciate any input on what works well and what doesn't.

I run mine from a single sheer bolt just above the frame rail to the the LCA bolt.

If you fabbed complete radius arms, just add a couple of tabs.

I've seen a single limiting strap used in the center. That is kind of what I was interested in.

I just use my shocks as my limiting on the wheels :shhh:

planning on using my tackbar brace to mount my center limiting strap from

I was thinking about running a 2" strap transverse across the front from rail to rail, with a touch of droop in it. I would then run a roller over that strap tied down to the axle. It would allow for the point of pressure to always be shared by both sides of the strap. I was then looking to do some sort of spring loading on the transverse strap to keep it slightly taught and the slack out of it to reduce it flopping around and banging on stuff.

Tom, it seems like most that run a center limiting strap run it around a cross frame track bar brace. I did mine using two straps, one from each frame rail to the center of the axle. I welded a tab to the bottom of the frame on each side, then two tabs on the axle tube right next to the center section. I don't currently have a cross frame track bar brace........I've had bad experiences with them due to lousy design of the two that I've run. With the first one the brace broke and then the track bar frame mount still ripped off the frame, the second one was made with rod ends on each end but was too close to the pan and on a hard hit it pushed the pan up into the crank.

To get the length, I flexed it up and measured to the center, then got straps that length. The straps don't limit articulation but do limit the axle dropping all the way out. Only thing was that I had to undo the straps for running fast back from the trail. Now, I run the straps with one twist in them on the trail, two twists for waterfalls, and no twist for running fast. My straps are pinned on the bottom so it's easy to undo them.

...pushed the pan up into the crack....

I think you've been smoking the wrong stuff.

I run a limiting strap on both sides. On the drivers side frame i use one of the upper track bar bracket bolts. There is a hole on the pass side that is a mirror of it. I just added some large heavy duty washers to keep from damaging the sheetmetal. On the axle end I added holes to my existing brackets and attach the straps in single shear. I put in two holes per strap on the axle end for a little bit of adjustment if needed. One trip on the setup and no problems so far.

Maybe the right stuff.

Fixed it.

I feel special when I can point out someone elses typo's.

any Pictures of the radius arm talked about above? and pics of limiting straps. I never saw one before and am interested.

Do a search for radius arms and you'll find 50,000 pics. Everything from home fabbed arms that look like the bought ones to lengthened stock Fords.

I wish I had photos to share, but I just don't!


I just built a Claytons Hard Arm 8" kit with rear coils for a good friend. We did the STAK 3speed and all the goodies. Having a problem with the rear having CRAZY flex. Front dont do diddly squat. We will be changing shocks to an adjustable RS9000 or MX6 for the cheap side.

Will running limit strap on all 4 corners solve problems? Or just bandaid them?

No sway bars, yet. I "think" I am going to have to put the stock one in the rear back on and possibly a antirock in the front. We dont want a crap load of travel, just balance. Since I do NOT know the numbers on the rear 4 link, I honestly dont know how its going to act.

Any helpful input to getting this solved? Havnt even ramped it, cuz no forklift or ramp around. Sucks to trailer all the way up, then figure out your coils front and rear fall out.:wierd:

old_man, do you have pics of your finished radius arm setup?

 

[tealcherokee]

i use the tow hook mounting hole in the frame, stick a bolt w/ an eyelet on the end through it, still allows you to use the hole for a bumper mount, and then weld a tab on the axle.

i use 3/16" coated steel line as well (as the strap)

I'll try and get you a pix tomorrow. I got busy working on it and forgot and now it's dark.
