Featuring massive 14" x 1.25" vented rotors and a high-modulus 4-piston caliper system, it delivers superior braking performance optimized for lifted vehicles with oversized tires. Engineered for durability and easy installation, this kit includes front and rear rotors, calipers, pads, and all necessary hardware, backed by a 3-year warranty. ## Description The TeraFlex JL/JLU–JK/JKU: Delta Brake System is the ultimate upgrade for JL/JLU and JK/JKU Wrangler models with oversized and heavier wheels/tire combos requiring increased braking performance. A must for 33-42” tires or heavy-laden overland rigs. Includes all the components required to upgrade both front and rear axles. Delta Brake Calipers feature a high-modulus bridge. Modulus measures a material’s resistance to elastic (recoverable) deformation under load. A stiff material has a high modulus, which means it only changes shape slightly under high elastic loads before returning to its normal shape.
