Rear shock stroke with 1 1/2" rear blocks?

[Hasty]

I searched the forum and wasn't able to find out if there is any conflicts with moving down from the 3" rear block to the 2wd 1 1/2"? My concern is with the stock shocks stroke bottoming out before full compression on the jounces. Thanks in advance for the input guys, loving all the sick ass Raptor knowledge I've been absorbing from the community!

Got underneath the truck today and the stock blocks measured at 2 1/2" with 6 1/2" of shaft till full compression. 4 1/2" from block to jounce and 6 1/2" from block to the jounce mounting point. I would imagine the jounce under full bump compresses 1" which would put me right at the limits with the 1 1/2" block. Searching the forums I didn't find any reported problems so it appears I answered my own question.

I was thinking of doing something similar, but I was just going to remove the rear block and cycle things out.

Did you do the modification, and do you have any photos?

Thanks!

THANKS! The rear is still a touch higher than the front, correct?

Did you end up leaving the front stock or have you gone up to mid-perch height in the front?

Yes, the rear does sit higher than the front but the front to rear height difference is approximately the same as mid-perch with stock rear block. I have the same rake as mid-perch but I'm just overall lower. I've considered installing the progressive front springs but not mid-perch again. I plan on keeping the rear as is until I upgrade the springs.
