GMC YukonExtended Brake Lines

Extended brake lines are generally required for lift kits in the 4–8 inch range, as seen in many Rough Country kits for trucks and SUVs. However, requirements can vary by vehicle and kit design. Always review the lift kit’s instructions and notes carefully to confirm whether extended brake lines are necessary or recommended for your specific application.

You need extended brake lines when you install a suspension lift kit or upgrade to longer-travel shocks that increase axle droop beyond what factory brake lines can accommodate.

Stainless steel braided brake lines resist expansion under pressure and offer better abrasion and heat resistance compared to standard rubber hoses, which can provide improved pedal feel.

Safely lift your vehicle until the wheels are just off the ground at full suspension droop - if the brake hoses appear taut, stretched, or near their limit of travel, you need extended lines.

Rough Country offers front and rear extended brake lines for various truck, Jeep, and SUV models. Add your vehicle to our fitment finder to see what brake line kits are available: https://www.roughcountry.com/extended-brake-lines
