## Overview

The TeraFlex Delta Brake Kit is a vehicle-specific, high-performance upgrade for Jeep Wrangler JK and JL models, featuring massive 14" vented rotors and advanced 4-piston calipers. Designed for lifted rigs with 33-42" tires, this 100% bolt-on system delivers superior stopping power, enhanced brake modulation, and corrosion resistance—all engineered for easy installation and reliable off-road dominance.

## 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.
