4" RC with 33s. What size bump stops?

I've had a hard time finding definitive info on correct bump stop size.

I have the 4" RC series II lift with the 2.2 shocks. I'm running 33s and have a ton of clearance. The 10 year old stock bump stops are so rotted they remind me of those coolers Kwicky Mart sells for $2. In a word, useless.

Any suggestions for replacements?

Trust me, they were well used before the lift. I haven't pushed the flex enough since to get to the not good point, thankfully.

helps a lot to know the extended & collapsed length of the shocks your running...
Thanks, I'll have to get RC on the phone tomorrow to get me the lengths of the shocks so I can use the chart. Maybe someone with the same shocks knows their length, so I can finger this out tonight?

Your between 2 to 2.5 inches. I have 2 in pucks in my lift. I didn't put them in since I was going to get the air bump style but ran out of money then got lazy and didn't put mine in yet lol. Maybe this week I will toss in my 2in pucks.

Nobody here can tell you for sure.

You need to crawl under your Jeep with a tape measure and figure it out.

1. How much room for uptravel do your shocks have?
2. How much uptravel do your tires have before they contact sheet metal?
3. How much room is currently between your axle and the bumpstops?

Measure all the above and you'll know how much longer or shorter your bumpstops need to be.

If #1 or #2 are less than #3, you need to extend the bumpstops until #3 is less than both #1 and #2.

just measure as the above pic shows...

If you can tell me the collapsed shock length, I can tell you what you need, but you'll have to pull the lower end off the mount and measure it anyhow.

I want your factory 07-up take-off/thrown out JK front/rear Lower Control Arms! Bent ones are perfect also as long as the bushings and cold cut rings are in good shape/useable

yep, shocks and brake line become limiting factor with the RC 4" without bumpstopping. my brake line is pretty tight at this pic checking out flex




another thing if you didnt get arms with a flex joint on them, the fixed arms put alot of stress on your lower CA mounts



over all flex isnt to bad though

CleanTJ, post a pic of the spring perch on the passenger side, showing the bumpstop cup & jounce bumper. i bet the jounce bumper isn't even compressed, and with those brake lines tight you can't turn & flexing at the same time....

For reference, when looking at the measuring diagram (pic) I see the point as the bottom flange of the steel cup.
Is that correct, and not the bump stop end ??



nice flex shot 1cleanTJ BTW
