sas oil pan kit with 10 inches over ifs?

My question is do I need to do the 2wd oil pan conversion if I use the front range offroad sas kit with 5inch leafs. They say the kit adds 2inchs of lift plus the lift of your springs. Mine being 5inch. It says 7inchs over ifs lift and 10 inchs over stock ifs. Would my 4wd pan clear the axle at full flex??

 

If you set up your truck properly, no. The t100 oil pan is NEEDED for the SAC.

 

With out a doubt you need it the front sump pan wont allow any up travel. Unless your building a bro truck and your doing it for looks but then you might as well just do a DB lift and save some money.
