Bump stops: I'm over thinking this

[MakJeeps]

Hello all,

We're pretty much following @CodaMan 's lift set up; https://wranglertjforum.com/threads/codamans-2004-jeep-wrangler-rubicon.9347/

We have everything sitting in the garage. Only area I am stuck on is the bump stop kit. I would prefer to cycle the suspension and axles to measure the needed bump stop extension, during installation. I have Googled, YouTubed and searched the Forums for days and all I can come up with is that I can expect roughly 1-1.5" extension "puck" for the front lower spring perch and 1.5-2" in the rear above the cups.
Unfortunately I'm unable to keep the Jeep off the road for a few days to order proper length parts. Assuming I need something in 1/4", 1/2" or 3/4" increments. So you can see where my wheels are spinning.

The Rock Krawler kit; Rock Krawler Bump Stop Extensions (Front and Rear) --RKSRK05611 Only deals in 1" increments. So if I was lucky enough for a 1" front and 2" rear measurement problem solved for $50. My "luck" usually won't run that way.

I guess I'm looking for options that would give us the most versatility to "mix and match" sizing as needed to attack this part of the lift.

Any advice is appreciated.


Thanks always,

John in NC

FWIW: Jeep has a 1" BL & 1" MML already installed and the plan is for 32s. Jeep is a daily driver and offroading is mostly on NC beaches 2-3 times a month.

I'll probably get shot down for this but I would just wait until after you get it all installed to measure for needed stops. Since you don't go rock crawling every weekend, you are pretty unlikely to get close to full flex in the short term.

Put it on, don't go mountain climbing, measure ASAP, order proper stops, install, go mountain climbing

Buy these and cut to length.

I agree with this, normal every day driving should not result in riding the bumpstops unless your drive everyday is through JV and Moab LOL! Get it all installed then figure out where your bump stops need to be before you get the suspension to flex out.

Yep. You ll be fine unless you go crazy .

 

[MakJeeps]

Thanks for the advice. Knew I was overthinking it. Guess I could pre-drill the front pad to save some time while I’m in there.

I realized I have not ordered that OME rear track bracket yet, could the same thinking be applied to it?

 

[bobthetj03]

You'll need the bracket, so plan to install it while the springs are out of your way. Hockey pucks work well too for bump stops. Cheap and easy to find.

Bump stops are not critical for everyday driving. Do the lift. Cycle the suspension and order the parts. Everyday driving will be fine without bump stops.

Maybe. Maybe not.

 

[billiebob]

Maybe. Maybe not.

True, I was thinking about defining "every day driving" but if you are not articulating on that "every day drive" bump stops do nothing.

You'd be surprised how much travel you use on a daily commute. ziptie test will show you is you have shocks with an exposed shaft.

About 5", occasionally 6" of up on mine according to the zip ties going to/from the grocery store.

you know that's a good point and you never know when you're going to come across some road construction or something.

Denver roads are not smooth. I've traveled to other places that were worse, like Chicago last month. There are plenty of threads from lightly modified pavement pounding TJs with broken shock mounts. I'm inclined to think that bumps matter quite a bit for a daily driver because we tend to hit problem spots far harder on the highway than we do on a fire road.

Yes it really wasn't wise of me to say not to worry about it earlier... Those bump stops are made for a reason.

I have about 4” uptravel on my front with a stock sway bar. And I seem to use it all in normal driving conditions. It is amazing though that with the jounce bumpers I dont notice bottoming out.

Is the diameter of the rear "extension" the same diameter as what is used as an extension of the front spring pad? Certainly that's not as big around as a hockey puck? I keep reading about people using body lift blocks like these, cut to length, but I can't get my head around the dimensions. Seems like a great value!

Thats the most interesting thing about Jeeps. Some things are pure precision and everything else is completely "git'r done".

...

The 2" diameter can be used on either the front or rear above the cup. The 3" diameter gets bolted to the front axle pad.

I just picked up 4 body pucks from Fat Bobs, they were like $4 each...

About 5", occasionally 6" of up on mine according to the zip ties going to/from the grocery store.

Our test drive loop which is also the way in and out of the resort, will generally bottom out all but the most well set up rear shocks.
