Check out our rear disc conversion kit for this model. We have the 10" drum kit HERE and the 11" drum kit HERE
NOTE: Rotors are now black e-coated to match our rear kit rotors (not shown in product pics)
Where to measure rotor thickness:

NOTE: All 1.25" thick rotors ship with an ABS tone ring. If you have a truck/SUV without front ABS, the tone ring can easily be removed.
Note for 88-91 standard cab trucks (except 454SS) with 1" rotor width: You can swap to 1.25" rotors by selecting the 1.25" rotor option above and using these DROP SPINDLES. If you prefer stock height spindles, you will need to source those from an 88-00 extended cab, 90-93 454SS, or 92+ in any cab configuration.
