Toyota 4Runner Brake Lines — 1st Gen Through 6th Gen

Brake Line Pros builds DOT and NHTSA certified stainless steel brake lines for every generation of Toyota 4Runner. Our 4Runner brake line kits are built for lifted, long-travel, and straight axle swap applications where factory rubber hoses fall short at full droop or fail under trail conditions. We cover 1st gen 4Runner brake lines (1984–1989), 2nd gen 4Runner brake lines (1990–1995), 3rd gen 4Runner brake lines (1996–2002), 4th gen 4Runner brake lines (2003–2009), 5th gen 4Runner brake lines (2010–2024), and 6th gen 4Runner brake lines (2025–present) including TRD Pro, Trail, SR5, Limited, and off-road builds running lift heights from 2 inch to 6 inch and beyond. Extended front brake lines and rear brake lines are available for builds running increased lift height, long-travel suspension, aftermarket shocks, or straight axle conversions. Stainless braided 4Runner 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, Total Chaos, and similar suspension systems. Every 4Runner brake line kit is pressure tested and individually inspected before it ships. Built and tested in the USA.
