By 2001 Dodge used a slip-on rotor on the CTD trucks - still 1.5" thick.Great info. I am looking for a rotor that is machined on the inside so I can use it on the outside of my hub. The 01 Chevy is this way but I cant get a wilwood caliper for the 1.5" rotor. My theory behind the wilwoods is a great caliper with 4 pistons so I dont have to use a huge master. The 97 dodge is cast inside so I would have to machine it to work adn I am looking for a simple rotor swap. These are going on a Volvo axle also. Is the chevy rotor machined inside?
99+ E350 rears are slip on also, but thinner. E450 rear rotors are 1.5 thick. Dunno if they slip on or not.
