Service bulletin Product Informat

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

MS23-17X EVO utilizes the latest axle manufacturing technology and will launch with a ratio range from 2.31 to 3.36 to accommodate the industry trend for engine downspeeding. When combined with optimized engines and transmissions, MS23-17X EVO will deliver increased performance and fuel efficiency that result from lower engine rpms at cruising speeds. In addition, MS23-17X EVO will expand on the benefits currently offered by the RS23-160 with higher GCW ratings and weight reduction. The MS23-17X EVO will be available for order in November 2017.
