1975 Chevrolet El Camino SS: Rally Wheels Arrive, the Six Returns
Colonnade-era El Camino; Chevrolet's 1975 data pages define the RPO Z15 SS option for the El Camino Classic. Team Chevelle's production totals give 33,620 El Caminos built, 3,521 of them with SS equipment.
United States · researched through 2026-09-22
This record's own key facts state that for 1975 the El Camino Classic SS option, RPO Z15, moved to 15x7 Rally wheels and GR70-15 radial white-lettered tires, keeping the SS grille, fender and tailgate emblems, upper body-side and tailgate stripes, and body-colored sport mirrors from the prior package. Its overview field is empty for this year, so the key facts carry the year's introductory description on their own.
This record's own key facts also state that a six-cylinder El Camino returned for 1975, the 105-net-horsepower L22 250, and that the largest available engine, the LS4 454 at 215 net horsepower, came only with Turbo Hydra-matic and was not available for California registration. A separate production-totals source gives 33,620 El Caminos built for 1975, of which 3,521 carried SS equipment, and this record's own production notes add that the SS figure had previously been held only as an unverified Wikipedia lead citing the very same production-totals page, a lead now resolved because that page has since been read directly.1
This record's own production rows carry exactly those two figures, 33,620 total and 3,521 with SS equipment, and its own notes state plainly that no Chevrolet factory production report was found for this year, so both counts rest on the single production-totals source. The same notes add that package contents are documented in the 1975 GM information kit but that no price for the year was found in that kit, leaving this record's own prices section empty even though the option and engine content around it is fully documented.1
This record's own engines section documents the 105-horsepower L22 250 six standard, a 145-horsepower L65 350 standard V8 not for California registration, a 155-horsepower LM1 350 available in California only, a 175-horsepower LT4 400 requiring Turbo Hydra-matic and California emission certification, and the 215-horsepower LS4 454, also Turbo Hydra-matic only and not available for California registration. Its transmissions section documents a standard three-speed for L22, L65 and LM1, and Turbo Hydra-matic across every engine, explicitly the only transmission offered with LT4 or LS4; this record's own options section is empty for 1975, a gap it carries without substitution.
This record's own paint section lists fifteen solid colors by code plus nine vinyl-roof colors, several of the vinyl choices cross-referenced to a specific list of body colors they could be paired with. Its interiors section documents fifteen trim combinations by code and description, split between El Camino and Classic cloth and vinyl offerings, none carrying a production count in this record's own fields.
This record's own specifications section documents a 116-inch wheelbase, curb weights ranging from 3,800 pounds for the six-cylinder Standard El Camino up to 3,950 pounds for the V8 Classic, and a GVW range of 5,200 to 5,750 pounds on GR78-15B tires. Its conflicts and unpublished leads sections are both empty for 1975, a gap this record carries without substitution even though its own production notes are explicit that no Chevrolet factory production report was found to cross-check the single production-totals figure this record relies on.
