Limit straps on a TJ

So it looks like I need some limit straps after stretching my axle. How do I measure how long the straps should be? From where to where do I measure?

I see straps are like 11" to 30"+, My guess is I should flex out the rig until my spring is about to fall out and measure from there, just not sure what points to measure from.

Anyone have pics from a Wrangler? Where are you mounting the straps?

Thanks!

That's how to measure, but the length of strap is the distance between the mounting points. Ideally you would mount from the frame to the axle, but you may have to come off of a bracket on the frame for packaging considerations. Keep in mind you can make the mounting point adjustable with different bolt holes depending on how everything is designed.
 
Once the springs are unloaded there is no need for the axle to droop further since there would be no weight on the tire to provide traction. Flex the suspension right to where it's unloaded and measure between mounting points -1", allows for stretch in the strap.
 
Did your clayton kit not come with coil retainers? If you strap it,measure your shock fully extended then strap it off an inch short of that so the shock wont have so much pull on it.

I don't want them, but they have been suggested to me to keep my springs from falling out. On my test run with the stretch, which was only URE, both springs came unseated and re-seated off of the spring perches.

you could also capture the coil... that would limit travel too...

I thought about that, but it also looks like the droop could go low enough to pull the spring past the bump stop which would keep it from re-seating on the upper spring perch. I haven't seen it do this yet, but it looks like it could.

Ordinarily the shocks will bottom out and prevent the suspension from flexing to the point where the coil can pop out.

I actually bought shocks with a down travel measurement hoping it would do what you are saying. But apparently there is still too much down travel to keep pressure on the spring.

Nope, no spring retainers.



I also wonder if a rear Anti-rock would work? My wife was bugging me to get one instead of straps. But, $30 for straps, or $400 for a rear Anti-rock....


Thanks for the suggestions so far!
 
anti-rock really wont work for that I dont think... atleast not exactly like you want probly...

i was thinking more along the lines of capturing both top and bottom of the coil to keep it from coming out period....

if using a strap, i would say to make sure you put it out of the way, or tie it back with a bungy or something, so it doesnt get snagged or caught on anything...
 
I have both anti-rock and straps on mine. Trial run to Tellico after installing my POS RocKrawler suspension my front springs were almost immediately ejected. Had to use heavy duty tie wraps to hold them in for the trip. I installed a anti-rock first to help with other issues, way too much body lean. It had no effect on keeping the springs in, unless you have it way tight but that limits articulation as well. Installed straps to combat the spring ejection problem, no problems since.

BTW, shocks are not designed to hold the weight of an axle especially in the conditions we subject them to.

I don't know about jeeps, but in the front of an application like a dodge ram the shocks limit downtravel before anything else, at least with factory suspension, so how could they not be designed to hold the weight of an axle?

Just because it happens does not mean that is what they are designed for... The top shock bolts on my Dodge are all messed up from over extending I'd bet.

When ordering limiting straps keep in mind they will stretch a little...

Not trying to argue your point but it seems to me that the Dodge engineers never invisioned a full size ram to be a true off road vehicle, like a Jeep, during the design process. Every mechanic I've ever spoken to on this issue seemed to agree that using shocks for axle limiting purposes was beyond their intended use. Straps are cheap, shocks are expensive, why argue?
