Extended Brake Line Kits for Lifted Trucks and Off-Road Builds

Stock brake lines are sized for stock suspension travel. Add lift and you add droop — and OEM lines will pull tight, restrict movement, or tear at full extension. Extended stainless steel braided brake lines give you the additional length your lifted rig needs to travel freely without binding or snapping under full droop.

The Limit Strap Connection

Brake lines and limit straps work as a system on any serious build. Your limit straps define your maximum droop. Your brake lines need to reach that droop point with clearance — not tension, not dangerous excess sag. If you haven't installed limit straps yet, your brake lines don't have a defined endpoint to size to. Install Bull Strap limit straps first, set to safe CV angles, then size your brake lines to the resulting droop distance.

This is the sequence professional builders follow: set droop limits with limit straps → spec brake lines to those limits → install and verify at full droop. Doing it in reverse order means you're guessing on line length.

Stainless Braided vs OEM Rubber

Stainless braided lines offer two advantages over OEM rubber: they don't expand under pressure (firmer pedal, more consistent brake feel) and they resist fatigue from the constant flexing that comes with serious off-road use. For a rig that sees regular trail duty, braided stainless is worth the upgrade over extended OEM rubber lines. The investment is minor compared to what a blown brake line costs you on the trail.

Sizing Guidelines

General rule: for every inch of lift, you need 1-1.5 inches of additional brake line length. A 3-inch lift needs 3-4.5 inches of additional line. But the correct method is measuring at your actual droop limit (set by limit straps), not calculating from lift height. Measure from the hard line end to the caliper banjo at full droop with the correct clearance, and spec accordingly.
