Mark, great comparison. The Safe-T-Plus # ST59YR is the heavy-duty version built for large diesel pushers with ZF IFS steering, while the Reflex is designed mainly for lighter Class A and C chassis like the Ford F-53 or E-450.

The Reflex uses coil springs for centering, but the Safe-T-Plus adds a sealed hydraulic piston that provides smoother, more controlled on-center feel -especially under the heavier steering loads of your diesel.

It’s basically the “pro-level” stabilizer - fully sealed, maintenance-free, and matched to the ZF steering geometry. You’ll feel the difference in the first mile.
