Cadillac CTS Parts
in Dubai
& the UAE

Three generations, three platforms, and a 2020 nameplate handover to the CT5 make the Cadillac CTS a precise-fitment exercise. The first generation (2003–2007) ran on the rear-drive Sigma platform. The second generation (2008–2014) moved to Sigma II and added coupe and sport wagon body styles alongside the sedan. The third generation (2014–2019) shifted to a stretched Alpha platform and returned to sedan only. None of these share suspension, brake, or body parts across generations. The CT5, which replaced the CTS for 2020, uses a different platform entirely, so CT5 parts do not fit a CTS. We stock ACDelco and GM Genuine at Ras Al Khor across all three CTS generations. Send your year, body style, and VIN on WhatsApp so we confirm the right generation before any part is pulled.

INVENTORY

Cadillac CTS Spare Parts: Three Generations on the Shelf

We carry shelf stock for all three Cadillac CTS generations at Ras Al Khor. Part families in regular stock include brake pads and rotors, front and rear suspension control arms and bushings, wheel bearings, stabilizer bar links, engine and cabin air filters, oil filters, and spark plugs. The first-generation CTS (2003–2007, Sigma platform), the second-generation CTS (2008–2014, Sigma II platform), and the third-generation CTS (2014–2019, Alpha platform) are all covered. ACDelco and GM Genuine are the OEM lines for all three generations.

Engine coverage differs by generation and build year. The first generation ran either a 3.2L V6 (standard in early builds) or a 3.6L V6, with a 2.8L V6 entry-level option from 2005. The second generation offered a 3.6L V6 at launch and a 3.0L V6 from the 2010 model year, plus the supercharged 6.2L V8 in the CTS-V. The third generation added a turbocharged 2.0L I4 alongside the 3.6L V6, with a twin-turbo 3.6L V6 in the V-Sport trim and a supercharged 6.2L V8 in the CTS-V. Oil filters, air filters, and spark plugs differ across these engine families. Send your year, engine, and VIN on WhatsApp to confirm which parts apply to your build.

GENERATION DECODER

CTS Generation Decoder: Sigma, Sigma II, and Alpha

The most significant fitment risk with the CTS is ordering for the wrong platform. Sigma, Sigma II, and Alpha are three distinct rear-drive architectures with no shared suspension geometry or brake components between them. Additionally, the second generation introduced coupe and sport wagon body styles that differ from the sedan in body panels, glass, and some suspension items. The table below maps each generation to its platform and the parts-relevant differences at each transition.

The year overlap between the second and third generations adds a further complication. General Motors began assembling third-generation CTS sedans in September 2013 as 2014 models, concurrent with the final production of second-generation sedans. Second-generation CTS-V coupe production continued into the 2015 model year. The 17-digit VIN resolves generation, platform, and engine code in one step. Send it on WhatsApp before ordering any suspension, brake, or body part.

FITMENT CHECK

CTS Parts Fitment: Three Platforms, Body Styles, and CTS-V Specifics

The three CTS generations share neither a platform nor a parts catalogue. Sigma, Sigma II, and Alpha each represent a distinct suspension architecture, brake geometry, and engine bay layout. A suspension arm sourced for a first-generation Sigma CTS will not fit a second-generation Sigma II or a third-generation Alpha, and vice versa. The simplest way to avoid this error is sending the 17-digit VIN before ordering; the VIN encodes the generation and build year without ambiguity.

Body style is a second fitment variable within the second generation. The Sigma II CTS was available as a sedan (2008–2014), a coupe (2011–2014), and a sport wagon (2010–2014). The coupe and wagon share the sedan's drivetrain and mechanical platform but differ in body panels, glass, and some rear suspension geometry. A rear glass panel, tailgate, or body trim from a second-generation sedan will not cross-fit a coupe or wagon of the same model year. If you are ordering body or glass items for a second-generation CTS, confirm the body style alongside the year and VIN.

The CTS-V is a further fitment boundary within each generation. All three CTS-V generations carried Brembo brake systems with larger rotors and multi-piston calipers specific to the high-performance variant. These Brembo components are not shared with the standard CTS or the V-Sport trim. The first-generation CTS-V ran Brembo four-piston calipers front and rear; the second-generation CTS-V ran Brembo six-piston fixed calipers on the front axle. Ordering CTS-V brake hardware for a standard CTS or vice versa is a fitment error. Send the VIN and we confirm which brake specification your build carries.

OEM & AFTERMARKET

ACDelco and GM Genuine for CTS: Three Generations Covered

ACDelco is the service-parts brand for the CTS across all three generations. ACDelco Gold (Professional) is the OEM-equivalent tier and covers brake pads, rotors, filters, and suspension components for Sigma, Sigma II, and Alpha builds. ACDelco Original Equipment (OE) matches the factory part specification exactly, the appropriate choice when fitment tolerance is critical, as it can be with suspension geometry-sensitive parts on the rear-drive CTS. GM Genuine Parts is the single-tier factory OE line. Both brands are on the shelf at Ras Al Khor for CTS applications across all three generations.

Engine diversity within the CTS model run means service parts are not interchangeable by year alone. A first-generation 3.2L V6 build takes different oil filter and air filter specifications from a 3.6L V6 build in the same generation. The second-generation 3.0L V6 and 3.6L V6 share the model year but have different service item requirements. The third-generation turbocharged 2.0L I4 has its own filter and spark plug set distinct from the 3.6L V6. Aftermarket alternatives are available for CTS where the customer specifies or where the application is cost-sensitive. The same documented-fault warranty terms apply as for the genuine lines: electrical components are non-returnable once fitted. WhatsApp the year, engine, and VIN and we advise the correct line and specification for your build.

WARRANTY

CTS Parts Warranty: ACDelco and Aftermarket Terms

ACDelco and GM Genuine Parts for the CTS carry a warranty against manufacturing defects. This covers brake components, suspension arms and bushings, filters, and mechanical parts across all three CTS generations. Aftermarket parts we supply for the CTS also carry warranty cover where the fault is documented. Claims require proof: a workshop report or a written fault description.

Electrical components for the CTS, including ABS wheel speed sensors, TPMS modules, and engine management sensors, are non-returnable once fitted regardless of brand. Before fitting any electrical component you are uncertain about, WhatsApp us the part specification and the fault code. We verify it against your CTS VIN and confirm the correct part for your generation and engine before you commit.

FAQ

Frequently Asked Questions

Do first-generation Sigma and second-generation Sigma II CTS parts cross-fit?
No. Despite the similar platform names, Sigma and Sigma II are distinct architectures. Suspension geometry, brake components, and body fitments differ between the first-generation CTS (2003–2007, Sigma) and the second-generation CTS (2008–2014, Sigma II). A Sigma suspension part will not fit a Sigma II build, and vice versa. Send your 17-digit VIN and we confirm which generation you have before anything is ordered.
Can I use Cadillac CT5 parts on a Cadillac CTS?
No. The CT5 replaced the CTS for the 2020 model year and uses a different platform. The CTS ended production in 2019. CT5 parts are not compatible with any CTS generation, including the third-generation Alpha-platform CTS (2014–2019). Always confirm you are ordering CTS-specific parts and not CT5 parts when sourcing. Send your VIN and we verify the correct specification before anything is pulled.
Do CTS-V brakes fit a standard CTS or the V-Sport trim?
No. The CTS-V carried Brembo brake systems with larger rotors and multi-piston calipers specific to the high-performance variant. The first-generation CTS-V used Brembo four-piston calipers front and rear; the second-generation CTS-V used Brembo six-piston fixed calipers on the front axle. These are not shared with the standard CTS or the V-Sport trim. The caliper dimensions and rotor sizes differ. Send your VIN and we confirm which brake specification your vehicle carries before you order.
How do I identify which CTS generation I have before ordering parts?
The 17-digit VIN is the most reliable method. Position 10 of the VIN encodes the model year, which maps to the generation: 2003–2007 is the Sigma first generation, 2008–2014 is the Sigma II second generation, and 2014–2019 is the Alpha third generation. The body style (sedan, coupe, or sport wagon) also matters for second-generation body and glass parts. Send your year, body style, engine, and full VIN on WhatsApp and we decode the generation and confirm the correct parts before anything is pulled from the shelf.
