Parker acquired Bayside gearheads in 2005 and continued to sell many of their gearhead products. Over time, advancements were made in gearhead technology, and Parker made the NE, NR, PG, and RA gearhead families obsolete in favor of the Gen 1 and 2 Stealth families. These more modern products include the PV, PX, PS, RX, and RS families.
Below are tables specifying the appropriate cross over from the obsolete models to the current Stealth models.
Or, use this spreadsheet to select the gearhead model, frame and ratio to lookup the replacement.
The mounting kit is a separate section. Select the old mounting kit part number to find the mounting kit for the new gearhead.
