14. We were also worried about the aluminum pinion support because the 9-inch has a lower pinion than even a regular Dana axle. This works well for us because we were having problems with driveshaft clearance of the high-pinion 44 front already. But the problem was that even with 40-inch-tall tires, we thought it would be grinding into rocks. Currie has released this cool pinion skidplate that perfectly mimics the F9 housing and hugs tight to the pinion. So tight, in fact, we’ve got barely 1⁄2-inch clearance around our 1350-series yoke.
