Equipped with a more robust engine, the ''OH-58C'' was supposed to solve issues regarding the Kiowa's power. In addition to the improved engine, it had unique IR suppression systems mounted on its exhaust. Early OH-58Cs had flat-panel windscreens as an attempt to reduce glint from the sun, which could reveal its location to enemies. The windscreens had a negative effect of limiting the crew's forward view, a previous strength of the original design.

The aircraft was also equipped with a larger instrument panel, roughly one–third bigger than the OH-58A panel, which held larger flight instruments. The panel was also equipped with [[Night vision device|Night Vision Goggle]] (NVG) compatible cockpit lighting.<ref name="58C cockpit">{{cite web |url= http://www.flightresearch.com/html/aircraft/oh58.shtml |title= Bell OH-58C Kiowa |publisher= Flight Research, Inc. |url-status= dead |archive-url= https://web.archive.org/web/20060522201749/http://www.flightresearch.com/html/aircraft/oh58.shtml |archive-date= 22 May 2006}}</ref> The OH-58C were also the first U.S. Army scout helicopter to be equipped with the AN/APR-39 radar detector, which alerted the crew to active anti-aircraft radar systems nearby.<ref name="cmh-1977">{{cite web |url= http://www.army.mil/CMH/books/DAHSUM/1977/ch10.htm |title= Department of the Army Historical Summary, 1977 |publisher= United States Army Center of Military History |url-status= dead |archive-url= https://web.archive.org/web/20040901065955/http://www.army.mil/cmh/books/DAHSUM/1977/ch10.htm |archive-date= 1 September 2004}}</ref> Some OH-58Cs were armed with two [[AIM-92 Stinger]]s and are sometimes referred to as OH-58C/S, the "S" referring to the Stinger addition.<ref name="amcom-storm">{{cite web |url= http://www.redstone.army.mil/history/netstorm/chapter3.html |title= Team Redstone's Role in Operation DESERT SHIELD/DESERT STORM |publisher= Redstone Arsenal |url-status= dead |archive-url= https://web.archive.org/web/19970429103523/http://www.redstone.army.mil/history/netstorm/chapter3.html |archive-date= 29 April 1997}}</ref> Called Air-To-Air Stinger (ATAS), the weapon system was intended to provide an air defense capability.
