Description
EZ-Fit NiCopp Brake Line Kit — Silverado & Sierra 1500 Extended-Cab Short Bed 4WD (2003-2007)
Stop wrestling with rusty hard lines and universal coils. The AGS EZ-Fit NiCopp® kit is engineered specifically for 2003-2007 Chevrolet Silverado 1500 and GMC Sierra 1500 extended-cab, short-bed, four-wheel-drive trucks. Each tube is CNC-bent to exact factory geometry and tagged for its location, so installation is simply clip, thread, torque, bleed. Nickel-copper alloy construction shrugs off road salt yet hand-tweaks easily for perfect alignment, and every line arrives pre-flared with OEM-style zinc-plated fittings—no flaring tools or guesswork required.
