that's exactly right.... same uptravel and bumpstop banging ride tho, flex is improved to the point that's it's not all useable...
So should I still have RC ship me the newer shorter rears, cut off the bumps on the shocks and install appropriate bumpstops?

I was ready to buy this lift when this topic came up now I don’t know what to do. Do you guys recommend buying this lift and getting longer bump stops, or buying the lift without the shocks?
Or is there another 3.5 lift out there that is not that much $$$$?

I'd buy the kit again, but not the shocks. yeah, the new ones are still too long for me, by 2.25".

unless im mistaken, "too long" is a little vague. I believe, again, unless i am mistaken, that the uptravel of the shock has to match the uptravel of the axle towards the bumpstop. though the shocks now have added uptravel, they still don't match (again, unless i have read a few threads wrong). therefore, yes, you may want to add bumpstops to make those two uptravel measurements match. the problem of bottoming out on a curb, as i understand, has been solved by the longer uptravel. but the problem of the shocks bottoming out before the bumpstops take action, has not. If i'm wrong i'll rescind. i just bought the darn lift last week. will install in about 4 weeks.

you may want to wait and take some measurements. whatever the distance from the axle to the bumpstop, subtract the distance of uptravel on the shock... then add that to your bumpstops. unless i have my brain in backwards that should give you = travel, therefore no shock damage.

I bet if you put 2 dudes, or some camping gear, in the back it would still bottom out going off a curb. my initial video was shot with no rear seat, no gear, and going slow. I have not tried with the new shocks, but i could bounce on the bumper and bottom the old ones out. (165lb) If you hit a whoop or bump at any speed, with any gear in the back, i would expect carnage. The new shocks only add 0.75" of up travel compared to the old, and still leave 2.25" on the factory axle bump stop when the shocks bottom out.

So you have any ideas? Buy a different shock from someone else?? If so what brand/size?

that's the best way to protect the mounts and shocks.. using proper axle mounted bumpstops, the rubber bumpers aren't needed.

the new shocks should be about 23" extended, 13" long collapsed and need around 1" extended bumptops in the rear... that's with the rubber bumper cut off.

OME has 22.5" extended, 13" collapsed shocks also, n66/n67, they don't need extended bumpstops in the front, but still need 1" extended stops for the rear. beings the new rc shock is also 13" the ome shocks don't change the situation, and running stock length shocks don't improve the flex... which is about the only other option..

stock rears are 19.5", 12.25" collapsed, the stock fronts are 21" 13" collapsed...


the whole thing about the long shocks is they don't offer any improvement in uptravel from the lift over stock. the shorter shocks give an additional inch, which makes quite a difference in ride quality on and especially off road. since the RC/OME shocks have no resivoir in them, they offer more overall travel from the smaller package.

No they haven't

The "new" shocks still have too long of a shock body. I'm a little upset that this problem came up and they sent out new shocks that still have the original problem that people were complaining about, just not as bad, but still there.

this is the measurements of a stock X tj.. the front spring rate is 128, the rear spring rate is 104, which is a common and good rate for a stock 4.0 tj. a rubicon/sahara model will have 129-130 front and 104-106 rears..

front... 3.75" max, 1.75" to bumpstop contact.



rear, 4" max, 2" to contact.



this is a rear 24" extended, 14" collapsed rc shock the "long ones", 3.25" max



this is the 14" rear with outboard shock relocation..



outboard mounts not only gain uptravel they also get rid of the shock rubbing on the tail pipe and the fuel tank.


I dont have a pic of the front with 24" extended, 14" collapsed shocks, they have about 4.5" max travel and need about 1" of bumpstop extension.

the new short shocks are an improvement and can also be relocated in the rear for more, which would about match the stock bumpstops having close to 5" rear uptravel and makes a good platform for 31-32" tires

my take on the new shock length is it's now at least matching the stock up travel and yeilds a bit more flex.... that's the best you're going to get from a 2.5" lift without shock relocation or simply reusing the stock shocks, stock shocks limit the tire size to 31" without a bl or longer bumpstops,
using longer bumpstops to fit larger tires?..., ya may as well use that much longer shock also and take advantage of the flex that comes from the longer shock... there are many variables, we just can't quite have it all without invasive body mods/shock relocation, that's how my rig got to where it is.
