I am having trouble finding a machine shop in Colorado Springs, CO that will drill the rear rotors on my JK to a 5x5.5 pattern.

Does anyone know what replacement rotors in a 5x5.5 pattern will work with the stock calipers?

Teraflex and DynaTrac have kits, but I am not interested in spending $500 at the moment.

Many thanks in advance!

 

Call a jeep dealer. They make a military jeep called the j8 that uses 5x5.5 pattern.

 

Thank you!

 

Just mark & drill your stock rear rotors. Take a dual-drilled rear axle shaft and install the wheel bolts in the 5x5" holes. Lay the rotor flat on the floor. Put the axle shaft onto the rotor hat with the wheel bolts and center hub through the corresponding holes. Mark the rotor hat using the 5x5.5" holes, magic marker does fine. Center punch the marks. Pilot drill with a 1/8" bit, then with a 9/16" bit. I use a cheap Ryobi drill press but you can do it with a hand drill. Done.

 

Yeah the D44HD J8 axles have the 5x5.5 pattern, I know the front rotors are 13"

 

No need to get new rotors, just drill 'em for the new pattern. I had to do this when I switched to Spyntec hubs four years ago. Got some Autozone rotors, marked them and drilled. Been on there for 40k miles, no issues.

 

Rotors are hub-centric. The wheel stud holes can be marked and drilled by hand or on a drill press.
