This is the TeraFlex JK Big Brake Kit is designed as a factory brake upgrade for the FRONT of a Jeep JK.
This is the answer for any JK owner looking for a performance brake package that will handle the increased braking requirements needed after larger wheels and tires are installed.
The 4303200 front JK Big Brake kit includes fits 2007 - Current Jeep 2 door and 4 door Jeep JK's.
-New oversized twin-piston brake calipers provides for more clamping force, with an increased surface area while decreasing brake fade. The oversize caliper will provide a more efficient method of heat dissipation for increased stopping power.
- New larger 13.3" High-performance, balanced & vented rotors keep the braking system cool for maximum stopping in all conditions. The dual wheel bolt pattern 5 on 5" and 5 on 5.5" allows for use on multiple wheel applications. A premium e-coat finish is durable and resists rust.
-New Brake Pads are high performance & optimized to provide maximum surface area and reduce brake dust and noise during extreme braking. The composite-resin, semi-metallic pads increase the lifetime of the brake system.
NOTES: ****The Heavy Duty Master cylinder Part# 4303450 is highly recommended on all JKs and may be required for those Jeeps with overly soft pedal.**** 2007-2011 JKs have a greater need and we highly recommend this master cylinder for those applications. 2012+ JKs feature a larger factory master cylinder and may not need a larger master cylinder kit.
