Front droop limit 2nd Gen

I recently installed a Toytec Boss 2.5 lift kit with Total Chaos UCAs and have noticed that, at full droop, the housing for the uniball comes into contact with the hi-misalignment spacer and has created a small gouge. This also seems to be the limiting feature of my droop. Is this bad? If so, why and how do I properly correct this issue? Limiting straps?

 

Doesn't surprise me. Uniballs while strong don't have tons more flex than the original ball joint hell depending on missalignment spacers they can actually have less.

Maybe a thinner (smaller OD) spacer?

 

What component normally limits droop?

 

The factory LCA is what limits droop on the front. Something isn't installed correctly if you are rubbing on the uniball.

 

The coilover.

 

My understanding is it is the coilover that is designed to limit droop on the front.

If you install a coilover that provides more droop I think the first issue you are likely to run into is the UCA contacting the coil so most aftermarket UCAs are designed to better clear the coil. Of course the ball on the UCA also needs to support enough droop too. Replacing the UCA and coilover to provide more than stock droop is usually referred to as "medium travel" here on TW.

Eventually the LCA will limit droop. Replacing the LCA to provide more droop is considered the threshold for "long travel" here on TW.

 

like stated, depends on the setup.

Stock upper and lower. First thing to hit will be UCA to coil, followed shortly by upper ball joint.

If an aftermarket UCA with extra flex is present (SPC / JBA arms, and uniball ones with high flex uniball / missalignment spacers) next would be tie rod (i think its the inner tie rod joint that binds first). Followed shortly by stock lowerball joint.


OP you might consider loosening the bolt that holds the UCA to the spindle and jack up your truck to see how much extra you need to get the full droop of the shock and not have the uniball be the limiting factor. Then if its maybe only 1/2 an inch, simply put a spacer between the lower misalignment spacer and spindle to raise the uniball up. This will change geometry of the suspension a bit but nothing that will cause any issues.

Also. OP. FIX THIS ISSUE. Another member on the forum had this same issue (uniball being the limiter of droop) and this over time caused the bolt that runs through the uniball to the spindle TO BREAK. think of the ramifications of that. The other member was lucky as it snapped in a parking lot at low speed if i remember correctly... but it could happen any time.

 

You cannot, nor should you, add any spacers. Common issue, and a limit strap is the correct solution.
