How To Help Constant Lane Drift When Getting On Highway With RV - 2010 Freightliner ZF IFS

Question:

Can the ST59YR help with the constant lane drift I get on I-10 when semis blow by me? My coach feels like it has a mind of its own. 2010 freightliner chassis motorhome with the zf branded suspension

Robert, that’s exactly what this stabilizer was designed for. The Safe-T-Plus # ST59YR will keep your steering centered automatically, so those pressure waves from passing semis or crosswinds won’t shove the wheel around.

On big diesel pushers with ZF IFS, the stock steering often feels too loose. This stabilizer adds controlled, hydraulic resistance right at center, giving you a calmer wheel and far less correction fatigue.

You’ll still be able to steer normally - it just tracks straight and stays there. Once you’ve tried it, it’s hard to imagine driving without it.
