Please do send pics because I had to install my factory bump stops with the beltech kit, I noticed machine marks on the 5" drive shaft it should be ok now though.The wenco drive shaft I have is due to the lowering kit on my rcsb. Even after knotching the frame, my drive shaft would still hit on occasions. So I had a 3 1/2 inch steel drive shaft replaced. Not sure if it's any better at high speeds but I don't hit anymore. I'll post pictures of the before and after if you want.
