Jeep Wrangler JK/JL & Gladiator JT 2007-2026, TeraFlex Delta Brake System, Front and Rear

Bigger, heavier wheels and tires add rotating mass, and the factory brakes were not sized for 33 to 42 in tires or an overland rig with a full load. Pedal feel fades and stopping distances grow.

The TeraFlex Delta Brake System includes the parts needed to upgrade both the front and rear axles: high-modulus calipers with pads and 14 x 1.25 in slotted, vented rotors. The caliper bridge is high-modulus, meaning it changes shape only slightly under load and returns to shape. Choose the 5x5 or 8x6.5 bolt pattern to match your wheels.

Bolt the calipers and rotors on each axle, bed in the pads and the Jeep stops with the confidence the new tires call for.
