8. Because of how low this Jeep is, we saved some cash by going with a regular low-pinion centersection. A factory nodular centersection is on the right. You can see the added ribbing and thicker pinion support section on the factory nodular iron case on the left. Currie offers high-pinion iron and aluminum centersections as well which utilize a slightly smaller 8.8-inch ring gear, so Currie only recommends the high-pinion centersections for vehicles up to 400hp and 35- or 37-inch tires.
