Speedway Motors is again the industry leader by offering a 100% stainless steel brake line kit. We know you dont want to cut corners on something as important as the brake system. Brake fluid and moisture in the brake lines and fittings are highly corrosive and attack softer metals.

Why settle for the anodized aluminum fittings offered by other companies? We start with 3/16″ stainless steel tubing of 304 grade (rated at 6000 psi) that is double annealed to allow easy flaring. Then, we offer a variety of fittings made of 303 grade semi-polished stainless for the most corrosion resistant line kit in the industry! Not all fittings are polished, but with a little elbow grease you can have beautiful brake lines.

Designed for conventional live axle rear suspensions. Includes two 20 foot coils of 3/16″ stainless steel line, nineteen -3 AN tube nuts, nineteen -3 AN tube sleeves, two -3 AN bulkhead tees, six -3 AN to 1/8″NPT adapters, two 90° -3 AN to 1/8″ NPT adapters, one -3 AN straight bulkhead fitting, two -3 AN to 1/8″ NPT female thru-frame fittings with stainless jam nuts, three -3 AN 18″ braided stainless lines, and three 3/8″ bulkhead nuts.

NOTE: These kits are designed to use 37 degree flares only. Do not attempt to use with standard inverted flare brake connectors, which are 45 degree.
