Probably not. There are a lot of companies that offer a pinion guard that just bolts up to the axle. A lot of makers put the two together becouse they only have a single 3/8" plate going across to weld to the axle tube. With this design you are getting over 60"(inner and outer of the boxing) of weld on the tube and another 10" on the cast housing. thanks for the interest.
I think this is your best looking buggy yet! That front clip looks killer with the grill hoop / trail stinger tied together. Looks like you could drop that thing from a 20 story building and it wouldn't hurt it.
