Poison Spyder Bombshell Diff Cover for Dana 30 Axle - Heavy Duty Off-Road Protection for Jeep Wrangler & Cherokee - Ideal for Rock Crawling & Trail Adventures

This is a complete install kit. You get the cover, grade 8 bolts, washers, silicone sealant and a 3/8 socket style fill plug. The outer surface of the cover is painted black, and the inside is raw cast iron. Very heavy cover and it seems like it can take some bashing from rocks. Should most likely outlast the Dana 30 axle itself if not give it a little bit of structural integrity at the differential area.
