Which Steering Stabilizer Bar Is Best For 2021 Entegra Aspire 40P With The ZF IFS Steering?
Published 10/07/2025
Question:
I’ve got a 2021 Entegra Aspire 40P with ZF IFS steering. Would the Safe-T-Plus ST59YR be the right fit for this freightliner coach?
asked by: Carl
Expert Reply:
Carl, yes, this is exactly the model you need. The yellow Safe-T-Plus # ST59YR is tuned for diesel Class A coaches with ZF independent front suspension, like your Aspire. It uses a heavier hydraulic centering spring designed for the extra steering load on large diesel pushers.
You’ll notice less drift in crosswinds and less steering correction on crowned roads. It’s a bolt-on install using the included ZF-specific brackets.
Carl, are you still on factory shocks? If so, pairing this with Koni FSDs makes highway tracking even tighter.
