Modifications to the RD-107 design have led to production of several distinct versions of the engine:

* '''RD-107'''（索引<!--индекс-->'''8D74'''）：原始版本。<ref name=npoem-el /> Used on the [[R-7 Semyorka|R-7]], [[Sputnik (rocket)|Sputnik]], [[Vostok (rocket family)|Vostok]] and [[Voskhod (rocket)|Voskhod]].<ref name=lprd-rd107 />
* '''RD-107K'''（索引<!--индекс-->'''8D74K'''）：Improved version of the 8D74. Used on the [[Molniya (rocket)|Molniya]] (8К78).<ref name=lprd-rd107 />
* '''RD-107ММ'''（索引<!--индекс-->'''8D728''' or '''8D74M'''）：Increased thrust over the 8D74K by 5%.<ref name=npoem-el /> Used on the [[Molniya-M]] (8К78М) and [[Soyuz (rocket)|Soyuz]] (11A511).<ref name=lprd-rd107 />
* '''RD-117'''（索引<!--индекс-->'''11D511'''）：Improved structural changes.<ref name=npoem-el /> Used on the [[Soyuz-U]] (11А511U) and [[Soyuz-U2]] (11A511U2).<ref name=lprd-rd107 />
* '''RD-107А'''（索引<!--индекс-->'''14D22'''）：Improved version of the 11D511 with new injector design that eliminated the high frequency combustion instabilities.<ref name=npoem-el /> Used on the [[Soyuz-FG]] (11А511U-FG), [[Soyuz-2 (rocket)|Soyuz-STA]] (372RN21A) and [[Soyuz-2 (rocket)|Soyuz-STB]] (372RN21B).<ref name=lprd-rd107 />
* '''RD-107А'''（索引<!--индекс-->'''14D22KhZ'''）：Chemical ignited version of the 14D22. Used on the [[Soyuz-2 (rocket)|Soyuz-2.1a]] (14A14-1A) and [[Soyuz-2 (rocket)|Soyuz-2.1b]] (14A14-1B).<ref name=lprd-rd107 /><ref name=rsw-soyuz2 />
