Important
What to Know Before You Buy
Engine-Specific Fitment
Big brake kits for the WK2 Grand Cherokee are split by engine. 3.6L V6 and 5.7L Hemi use one set of kits; 6.4L 392 and 6.2L Hellcat Trackhawk use a different set. Do not mix — verify your engine before ordering.
Wheel Size Requirements
Brembo kits use 15" (380mm) rotors. The Grand Cherokee typically came with 18" or 20" wheels. Verify clearance with your specific wheels.
Front vs. Rear vs. Full Kit
Front-only upgrades deliver the biggest improvement. For balanced braking, pair a front kit with a rear kit. Brembo sells front and rear separately for each engine application.
Brake Fluid & Bedding
Flush brake fluid when installing. Follow the bedding procedure for optimal performance. Trackhawk owners: these kits handle the extra weight and power.
