Floating Power – Plymouth PA Rumble Seat Sport Roadster

In July 1931 Chrysler announced a new Plymouth model for 1932 the PA which apart from dimensions like the 109″ wheel base and 196 cui 4 cylinder motor size shared little with the Model U which it replaced.

Despite being Chryslers budget brand the PA model featured a flying lady sculpture adorning the radiator, the item was designed by Herbert V. Henderson and manufactured exclusively for Plymouth by the Jarvis Company in Grand Rapids, Michigan.

One significant difference between the Model U and PA was the “Floating Power” mountings for the latter which were developed by Owen Skelton to minimise the inherent vibrations caused by a 4 cylinder motor. Owen found that by using rubber and affixing the mountings along the motors center of gravity axis which slopes from front to rear he could significantly improve the comfort for occupants of a vehicle.

Within months of being patented Floating Power was adopted by all Plymouth and Chrysler models and would remain a feature of MOPAR vehicles over the next 28 years.

Production of the PA came to an end in July 1932 with 106,896 examples including a variety of 2 and 4 seat body styles.

Floating Power and a commitment by former Ford employee, now head of the Plymouth brand Fred L. Rockelman to give his customers more car for their money helped Plymouth reach No:3 in the sales charts replacing Buick in 1931, a position it would only relinquish in 1954 when Buick recaptured 3rd spot.

My thanks to Geoffrey Horton for sharing these photographs, of a 1931 rumble seat “sport” roadster,which he took in a California car park in 2012.
