guys with the wrap trap...

[destroyer000]

anyone with the wildhorses wrap trap care to take some measurements for me? ive got a few pieces of dom and some heims kicking around id like to use up and think they would work great for this project. i noticed with the 5.5 deaver springs i have a bit movement on the rear pinion.. anyone willing to get me the length of the tube? iam going to assume its going to be about parallel with the drive shaft angle? from what i can tell the bars going to be maybe 22-24 in in length? thanks guys!

You're better off building a torque arm with a shackle IMO. The Wrap Trap Wildhorses sells is going to bind by nature and it's got a big bushing I believe to allow some movement.

i thought about going this route but its a pavement pounder... figured i can use a radius arm bushing for the front mount and its tucked up out of the way.. i dont plan on doing much articulation with it :-*;D

I can check mine out tomorrow after work and get some measurements. Hopefully someone will have the info to you before then.

Actually the torque arm - ladder bar design is worse for binding than the Wrap-Trap. Search Toyota forums for broken frame cross-members caused by torque arms - ladder bars. Search cK5 for problems with torque arms - ladder bars shearing their bolts. Most all of those guys ran it with a shackle, yet they're still generating forces big enough to break frames and shear off big bolts.

Think about this, How much does your pinion angle change if you totally droop the axle i.e. rear tires completely off the ground? I'll guess about 3°-5° as that's about the range that mine did when I did this test a number of years ago.

Think about how much the pinion angle will be forced to change with a torque arm - ladder bar under there. It will be double, maybe triple that.

Everyone looks at the shackle in this design as some kind of miracle cure for binding. It ain't. It does relieve the binding that the leaf spring's change in effective length would induce, but it does nothing for the binding that the torque arm - ladder bar causes by forcing the springs to twist in an 'S' shape when that pinion angle is forced to change by the torque arm - ladder bar.

If the Wrap-Trap isn't enough traction control, and it does have its limits, then you're probably playing with the big boys on the big trails and its time to either back off or link the rear.

that would be awesome! thankyou!

I recently installed the Wrap Trap and it works great. I've not had any binding issues. It totally solved my axle wrap problem. But I have a stretched frame so my measurements would probably not work for you. You want the front heim joint to be located at or very near the front spring hangers location.

I built a torque arm, broke it, built another, broke it, another, repeat. One broke off-road, the rest all broke on pavement.

The final fix, a set of front axle wedges welded to the axle, one front radius arm. Farm store 3-point tractor heim that fit the stud on the radius arm. Cut the spring shackle bracket off a frame rail and welded the whole bracket to the Bronco frame. Was going to use the stock shackle and weld the heim to that, but in the end I just got a poly bushing and sleeve to make my own.

That final version was very simple, very strong, looked remarkably stock (since the arm is a stock Bronco part but on the other end). Road great, fixed axle wrap, took hard launches, did everything perfect. Took a few tries at making a better mousetrap before learning it already existed and just needed to be moved.

I guess nitrous was a bad idea. Interested. Pics?

FYI >> The Duff old school traction bars work well.

What about something simple like that made from Dom tube?
Length is critical to minimize binding, but figure nothing you build to control axle wrap with follow the same cycle as a pair of leaf spring.

Sure, they are about 10 years old

That's cool.

I was able to get some measurements. The arm from where the heim joint threads in to the end of the threaded portion on the other end is 20-1/8". The threaded portion is 3 inches long.
Hope it helps. Good luck with the project!
