Re: 1967 C40 Rear Axle Rating?

Post a pic of the rear axle, it's either 11k, 13.5k, or 15k pound rear. It's more than likely you have the upgraded 5k front axle with the 11k rear=16k gvwr. I'm not postive what RR stands for but something to do with the rear. 7.5k leaf spring option is the 15k rr springs on your spid
