392 shocks on JLUR Springs

[idlingmike]

I picked up some 392 shock/spring take-offs a couple of months ago for a JLUR, then moved to a new place. Factory JLUR clears the garage door by about 1-2 inches, so it's staying a lift is out of the question. Not really a fan of the off pavement ride of the rubicon shocks and am thinking to throw the 392 shocks on the factory JLUR springs. If someone can look over my thoughts.....

According these are the min/max lengths
15.75 / 23.625 JLUR front
17.5 / 26 JLUR rear

16.75 / 24.75 392 front
18 / 27 rear



Based on other 0-1.5" shock upgrades, I do not think the springs will fall out fully flexed out.
Both 0-1.5" Bilstein 5100's, Fox have longer front fully extended lengths
Falcon 0-1.5 are rears have longer 392 rear fully extended lengths

Longest collapsed length front shock for 0-1.5" is FOX IFP at 16.25, which is 0.5" shorter than the 392 front making me think I may need to extend the bump stop that much.
Longest collapsed length of rear shocks for 0-1.5" is 17.5" also making me think I need a 0.5" taller bump stop as well.

Given I should get roughly 1 inch more droop from the 392's, I think this should still be an upgrade.

I'm running 392 shocks on my JLR with stockish height JLUR front springs. I think it rides pretty good for what it is, but there's always room for improvement.

Yes, you do need to extend the bump stops. I'm using the Metalcloak DuroSprings which are supposed to be 1" longer than stock when fully compressed, but they are much more progressive than the factory bump stops.
