Service bulletin PI-08-006

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.

Hendrickson released a product update regarding enhancements made to the ULTRAA-K suspension. One enhancement was the ZMD downstop which will now feature a more robust connection for improved performance and fewer parts for simplified installation. Another enhancement is to the Pivoting mud flap bracket which will now feature welded-on nuts for easier mud flap installation.
