The diff bulkheads were designed for extreme durability, while providing comfortable access for tuning and upkeep. Diff bulkheads are an essential chassis component, housing both front and back differentials and providing mounting points for the suspension mounts and shock towers. To enhance the consistency for the differential performance throughout each run, the apparatus package covers are milled down for extra venting to simply help get a grip on diff conditions. This prevents overheating the diff natural oils and guarantees more consistent managing during long mains and stretches periods between rebuilds. Fits both GTX and GTXE.
