In August 1960, the first Peterbilt trucks were assembled by the Newark, California, factory; production increased to 800 vehicles for 1960.<ref name=":8" />  Coinciding with the introduction of the new factory, Peterbilt debuted a redesigned "Unilite" cab for its conventional trucks, distinguished by larger windows and a redesigned interior (including an all-new instrument panel).<ref name=":11" />  In an organizational change, Pacific Car changed its ownership status of Peterbilt, converting it from a wholly-owned subsidiary to a division within the company, making it the sister company of marketplace rival Kenworth (a division since 1946).<ref name=":12">{{Cite web|title=PACCAR Inc|url=http://www.historylink.org/File/4272|access-date=November 5, 2021|website=www.historylink.org|archive-date=November 6, 2021|archive-url=https://web.archive.org/web/20211106220747/https://www.historylink.org/File/4272|url-status=live}}</ref>

In 1965, Peterbilt introduced the Model 358, largely replacing the 351 (which remained in production).  The first Peterbilt conventional with a tilting hood, the 288/358 replaced a fixed radiator (and grille shutters) with a grille surround attached to the aluminum hood (a fiberglass hood was added as an option in 1972<ref name=":11" />).  Serving partially as a grab handle, the Peterbilt "bird" hood ornament made its debut (a feature remaining in current production nearly unchanged).<ref name=":11" />

In 1966, the company expanded its model line beyond highway tractors, reintroducing heavy-duty trucks as part of its model line.  Above the Model 341, the Model 383 was a 6x6 truck primarily for off-road construction use.<ref name=":11" />

In 1967, Peterbilt introduced the Model 359 highway tractor.  Similar in design to the 358, the 289/359 also used a tilting hood, but was fitted with a larger grille (to accommodate larger diesel engines).

In 1969, Peterbilt expanded its production capability, opening a facility in [[Madison, Tennessee]] (suburban [[Nashville, Tennessee|Nashville]]).<ref name=":7" />  Along with the ability to meet additional product demand, the location was chosen to serve customers closer to the East Coast.<ref>{{Cite web|title=StackPath|url=https://www.forconstructionpros.com/trucks/trucks-accessories/press-release/11295703/peterbilt-motors-co-paccar-peterbilt-celebrates-75year-milestone-anniversary|access-date=November 5, 2021|website=www.forconstructionpros.com|date=January 16, 2014 |archive-date=November 11, 2021|archive-url=https://web.archive.org/web/20211111095040/https://www.forconstructionpros.com/trucks/trucks-accessories/press-release/11295703/peterbilt-motors-co-paccar-peterbilt-celebrates-75year-milestone-anniversary|url-status=live}}</ref>  As part of a revision to the cab design, the 282/352 COE adopted the name "Pacemaker".{{citation needed|date=November 2021}}
