Brake Line Pros builds DOT and NHTSA certified stainless steel brake lines for the Lexus GX550 (2024–present). Our GX550 brake line kits are built for lifted and off-road applications where factory rubber hoses fall short at full droop or fail under trail conditions. Extended front brake lines and rear brake lines are available for GX550 builds running increased lift height, aftermarket shocks, and long-travel suspension setups. Stainless braided GX550 brake line kits feature a PTFE inner core and precision-machined fittings for improved pedal feel and long-term durability on street and trail. Compatible with all DOT brake fluids and built to work with Icon Vehicle Dynamics, Old Man Emu, Bilstein, Fox, King Shocks, and similar suspension systems. Every GX550 brake line kit is pressure tested and individually inspected before it ships. Built and tested in the USA.
