Went and picked this axle up out of a 2006 FX4 Level II with 8,xxx miles on it It has 4.10 gears
My truck came stock with 3.55 gears. Trying to turn those 31"tires was not easy for it
I saved roughly $549.00 by not having my axle regered. I was quoted $1000.00 from a shop
Got it all painted up for the install Looks alot better
Before
After
The install went fairly easy probbaly to easy for me. I was waiting for my axle to come out the back when we drove around the block.
I can definatly tell the diffrence when I take off and just going down the road.
Just have to remember monday after work to re check the u bolts and check my axle fluid again
Next weekend im swaping my stock blocks back in in place of the FX4 blocks didnt relize the size diffrence. When we were done I noticed the front lower than the back. I may be able to crank my t-bars some more.
My extra lift problem
Old block 2"
New Block 2 1/2" plus axle diameter 10 1/4", the old axle was close to 8 5/8".
