The side belt extension is useful for certain applications where a longer lap belt is needed (BMW 2002, Offroad trucks). Comes in all colors and can be installed in any rallye style belt (Cross/Autocontrol/3/4) except for the Quick-Fit. Comes with 30" of webbing and a sewn in bendable bolt-in bracket.
Please be aware that proper geometry is paramount for the lap belt mounting point, and the side belt extensions make it very easy to anchor to a point that is improper. Please only use this part if your situation requires it. A longer lap belt is also not as safe as a short lap belt.
