Description
EZ-Fit NiCopp Brake Line Kit — Silverado & Sierra 3500 Standard-Cab DRW (2003-2007)
Give your one-ton GM workhorse the corrosion-proof stopping power it deserves. The AGS EZ-Fit NiCopp kit is precision-bent and location-tagged for 2003-2007 Chevrolet Silverado 3500 and GMC Sierra 3500 standard-cab, dual-rear-wheel chassis. Every nickel-copper line drops straight into the factory clips—no garage-floor bending, no guessing. Pre-flared with OEM-style zinc-plated fittings, the kit installs with common hand tools: clip, thread, torque, bleed, done.
Key Features & Benefits
Exact DRW Routing – CNC bends follow the long, wide 3500 frame and dual-wheel axle layout perfectly.
NiCopp Alloy Tubing – DOT-approved, rust-proof, burst-rated to 10 000 PSI and heat-safe to 1 800 °F, yet easy to tweak for perfect alignment.
Pre-Flared with OEM Fittings – Double flares and metric threads eliminate on-truck flaring or adapters.
Complete System Coverage – Includes master-cylinder, ABS block, front, rear, crossover and over-axle lines, plus new clips where required.
DIY-Friendly Tags & Guide – Each tube is clearly labeled; an illustrated diagram slashes install time.
Lifetime Durability – Resists salt, heavy towing vibration and frame flex—engineered to outlast the truck.
Swap out every rusted steel line in a single afternoon and hit the road—or job site—confident your brake system is as tough as your Silverado or Sierra 3500.
