Good To Know

Q: Are these lines sold as a pair? A: Yes, the set covers both front brake lines for one axle. Confirm your truck's lift height before ordering.

Q: Will these fit a stock-height truck? A: They are extended for lifted applications, so verify routing and length on a stock setup. Check fitment against your model year and lift.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
