Fitment note: Confirm brake fitting thread, hose length, bracket type, front axle, suspension travel and DOT/legal compliance. Do not use on a vehicle with incompatible drum/disc fittings.

Product Overview

The flexible brake lines connect the fixed hydraulic tubing to moving front brake components, allowing suspension and steering movement.

A lifted suspension needs adequate hose length without stretching at full droop or rubbing at full lock. Wrong hose fittings can leak or interfere with braking.

Confirm brake fitting thread, hose length, bracket type, front axle, suspension travel and DOT/legal compliance. Do not use on a vehicle with incompatible drum/disc fittings.

Frequently Asked Questions

Is this an OEM part?

No. Unless the product listing explicitly states otherwise, this is an aftermarket replacement. The manufacturer names and OE references identify applicable equipment, not the maker of this item.

How do I check fitment?

Confirm brake fitting thread, hose length, bracket type, front axle, suspension travel and DOT/legal compliance. Do not use on a vehicle with incompatible drum/disc fittings.

What if my model year appears above but the part looks different?

Do not install it based on the model year alone. Factory equipment changes by engine, build date, trim, mounting style, and option package. Match the original part number and physical connections first.
