Can anyone please tell me if the 3" or 4" Evo Plush Ride Coils will stay seated at full flex with Fox Remote Resi 28.3" long shocks, (28.3" open) I would prefer to have 3" but will go with 4" if needed.
At the moment I have 3.5" AEV Coils and they are too short at full flex.
Any help would be appreciated.
Yeahright,
I currently have my 2013 JKUR up on jack stands and am installing a lift kit (no shocks or springs installed on front end but everything else is in place, so I can raise/lower the front axle as I want). To help you obtain a quantitative answer to your question above, I made a couple of measurements for you.
First, I fully raised the driver’s side of the front axle so that the 3 inch bump stop hit the metal bump stop post. Next, I lowered the passenger side of the front axle so that the distance from top of the inside of the shock tower to the center of the lower shock mount bolt hole was 28.25 inches. This is a worst case condition (there may be others). I then made the following measurements:
Distance from lower spring perch to rubber isolator within the upper spring mount = 20.5 inches
Free Length of EVO MFG 4 inch Enforcer Spring (which I have on hand) = 21.00 inches
I would say that under “a” worst case condition, the 4 inch EVO MFG coil will just work for your situation. You may want to take Drew’s advice above with the spring retainer brackets.
Speculation – I would venture a "guess" that the 3 inch EVO MFG coil will come unseated. You need to find the “free length” of that coil to determine for sure (using the measurements above).
Hope the above helps,
Alan
