Description
Lifted Broncos have more axle travel and therefore need longer axle to frame brake lines to get the most from their suspension.
Our custom-built brake lines are stainless steel and DOT approved for street use as well as being longer to accommodate suspension travel. (Beware, many replacement lines are not DOT approved!) These lines won’t swell under pressure as rubber ones can. The smaller inside diameter increases pressure, which improves pedal feel and brake response.
We have these specially made so you don’t have to guess when it comes to the safety and soundness of your brakes.
NOTE: These are the lines that go to the differentials(axles), not the caliper lines! Fits stock to 6″ lifted 66-77 Broncos. 66 &67 may need to be adapted to fit the front hose. Product appearance may vary from photograph but still fit and function as intended.
