Does it fit a Laredo, Limited or the Trackhawk?
- No. It is the 380 mm disc for the Grand Cherokee SRT8/SRT and Durango SRT front brake; standard trims use a 330 mm disc and the Trackhawk a 400 mm disc.
Is this sold as a pair?
- No. Each box holds one rotor, so order two to replace both sides of the front axle.
When does the rotor need replacing?
- A new rotor is 34 mm thick; replace it once it wears to the 32 mm minimum thickness.
Is it corrosion protected?
- Yes. A UV paint finish covers the outer edges and hub.
