The TeraFlex Delta Brake System: JL/JLU–JK/JKU is the ultimate upgrade for Wrangler models JL/JLU and JK/JKU with oversized and heavier wheels/tire combos that require increased braking performance.
A must for 33-42” tires or heavy-laden overland rigs, it includes all components required to upgrade both front and rear axles.
Delta Brake Calipers feature a high-modulus bridge, which measures a material’s resistance to elastic (recoverable) deformation under load.
A stiff material has a high modulus, meaning it only changes shape slightly under high elastic loads before returning to its normal shape.
