Been a while since I posted much. Recently got my JTR back from having 5.13s installed in the axles. While I was at it I installed one piece RCVs axle shafts and deleted the FAD. First off I will say the JTR runs really well with the 5.13s and 37s. Not a huge seat of the pants difference but the engine definitely has alot less stress. The trans upshifts very quickly. Doesn't need to hold each gear as long. I find myself on backroads cruising comfortably around 50mph and the trans will be in 8th gear. It is smother and downshifts are more controlled with less engine reving unless burying the pedal. On highway it no longer hunts between 6, 7, and 8 gear. It will upshift to 8th and hold the gear, even pull in 8th until demand requires a downshift.
Having the one piece axle shafts and FAD deleted has shown no major issues. The jeep has a little heavier feel to it and in the steering but nothing unacceptable. Basically just like the JKs felt. No vibrations noted from driveshaft . I will say that shifting into 4WD is MUCH easier. I assume since there is no longer any delay or resistance as FAD engages that it makes it easier. Very smooth. Let off gas pull lever and back on it. Just like in JKs. Overall very happy with it.
Now to the next mod....LOL. Either sit back and wait and see if the 392 is offered in the Gladiator and start over or this spring I'll move forward with a Magnuson Supercharger. I know not everyone's cup of tea but I like the idea of additional power. While hands down not equal to a V-8, the 440+ crank HP for approx 6500.00 is a nice boost without boning up 20+K for a V-8 swap. The reviews are positive so far. And the money saved will eventually go to putting 60s under the JTR and upgrading to 40" tires.
