Won't I hit the spring perch with my shocks without the extension or relocating the entire mount? Is there any way I can avoid this without cutting off and welding new mounts?

Honestly I had never heard of the savvy skid till now. EMP at the time seemed relatively nice and affordable.
well, neither can I, that is pretty much the standard with lift kits, there are a couple now, that have figured out a long shock for "more flex" can't/wont flex as much as a shorter shock with balanced travel. some still send out and recommend OME 2.5" coils with OME N67L shocks that are 14.5" collapsed with 2" extensions for the rear, STILL, NOT ENOUGH, they are just too long without mount relocation for a 2.5" lift, about perfect for a 4", physical mount relocation not bolt on extension/shock shifters need to be used.

the Rancho kit comes with 2" front and rear extensions, 13.75" max collapsed shock length should be used, rotating the pinion up gives more room for longer shocks on the same extension but will damage the shock bodies on the springs/buckets, using a "shock shifter" will put you back to square one as far as bumpstop extension is concerned.

Ok well how much bumpstop front and rear will I need not to hit the fenders if I have 35" tires? I think you had mention 3 in the front and 2 in the rear before. Remember I have a 1" M.O.R.E. Body lift and fresh poly body mounts.

It looks like there's no avoiding it if I want to use these shocks. I am going to have to modify at least my rear shock mounts. I would like to set my bumpstops in order to be about equal to what would hit the body with 35" tires then adjust the mounts as necessary. I think I should be pretty close in the front running the 15.875" collapsed shocks and in the rear it looks like I will have to drop my mount quite a bit. Still need a good estimate for what the tire bump length is for 35 inchers with a 1 inch body lift. Do you thiink this kit from AEV would do the trick?

AEV Shock Shifter Kit (NTH23100AC)

I believe it is a duplicate of the old Nth Degree Kit like the one installed here:

Based on the chart at the beginning of this thread, it looks like I will not need any bumpstop extensions for the following setup (which I found from another thread that doesn't have a discussion of bumpstops):

I'm installing H&R springs (part# 52109) to a 2006 LJ that is otherwise stock. Those springs are designed to lift the front by 1.5" and the rear by 1.1".

I'm installing Bilstein 5100 shocks as follows:
Front:
Part No. 24-186810 (for 0"-2" lift height)
Collapsed Length (In): 13.06
Extended Length (In): 21.18
Rear:
Part No. 24-186827 (for 0-2" lift height)
Collapsed Length (In): 12.81
Extended Length (In): 20.08

Tires will be LT 245/75R16 (approx. 30.5") on 16x8 wheels.

Can I get by without bumpstops? Chart seems to suggest yes for the front, but not sure about the rear. Any help would be greatly appreciated.

Thanks!

Mudb8, any thoughts on the above? Just looking for some guidance.

i'm not mudb8, but looking at those compressed shock lengths, looks like you'll need 0.5" or so bumpstop extension in rear. Fronts will be fine. That will be a great combo for DD on 31s.

How would a 1" BL added to 90FORDF150's set up affect the bumpstop, it at all? I've already got a 1" BL, no MML, and am thinking about the H&R/Bilstein combo for my LJ. Running 31's now, might go to 32's when the 31's are worn out.

A BL doesn't effect bumpstop length, at least not as far as preventing the shocks from bottoming out is concerned.

Exactly right.....

won't affect the bumpstop length at all.... shock length only.

a bl on a tj opens the option of a longer shock from and only with upper shock mount relocation.

Awesome. Thanks for the additional input. Much appreciated! I'm wating for the springs to arrive, and then I'll be installing everything. I'll let you know how it goes.

One more thing ... (sorry to keep asking). Any recommendation for the bumpstop extensions in the rear? Again, thanks so much for all the guidance.

JKS has an adjustable bumpstop kit with a .75" option. Seems like a good kit and I can keep the rest of the components for more bumpstop down the road if I decide to add a different lift setup.

How does a body lift affect the situation with respect to bumpstops? For example, if the recommendation is no extension in the front and .5" in the rear without a body lift (given my setup described above in earlier posts), how would the situation change if I were to add a 1" BL and went to 32" tires instead of sticking with 31s?

Bumpstops are extended for three reasons. Preventing dampers from bottoming out, coil over compression and tire/fender contact.

A bodylift has no bearing on shock or coil compression. For what you're wanting to do, adding a 1" BL gains tire/fender clearance. The upper shock mounts are attached to the frame not the body. Your rear bumpstops will be extended to prevent the shocks from bottoming out, and couldn't care less how high you lift the body off the frame.
