Fitment on a used shock absorber varies by vehicle, so a bit of detail goes a long way. Our request form covers what breakers need to know, so every quote you get back is for the correct part:
The Signum was produced from 2003 to 2008 as a single generation, based on the Vectra C platform. There was a facelift in 2005, and while the basic suspension architecture remained consistent across the run, whether shock absorbers interchange freely across the 2005 facelift boundary is something you should confirm with the breaker against your registration, as damper specifications can vary mid-generation.
The 2004 car sits in the pre-facelift period and the 2006 in the post-2005 facelift period, so you are crossing a known production boundary. The suspension layout is shared across the generation, but whether the specific damper units interchange across that 2005 facelift line is not something that can be guaranteed here - give the breaker your registration so they can check the exact part numbers before you commit.
Yes, engine size can affect fitment because heavier or more powerful variants sometimes use uprated dampers to cope with the extra weight and performance. When contacting a breaker, quote both your engine size and your registration to make sure the unit they have matches your specific car rather than just the model name.
Yes, always specify the side - nearside (NS, kerb side, left) or offside (OS, driver side, right) - because front and rear shock absorbers are handed and not interchangeable between sides. Getting the side wrong is one of the most common fitment mistakes, so double-check before ordering.
Trim level does not affect shock absorber fitment on the Signum - Design, Elegance, and Elite are cosmetic and equipment grades rather than distinct suspension specifications. Bear in mind that if a car came with optional sport or lowered suspension, the damper rates could differ from standard, so ask the breaker to confirm the specification of the unit they are selling matches yours rather than assuming trim alone is the deciding factor.
The Signum shares its platform with the Vectra C, and there is a reasonable chance of commonality in suspension components, but the Signum's longer roofline and different rear bodywork mean you should not simply assume parts are identical. Route this question directly to the breaker with both registrations, as they will be able to cross-reference part numbers and confirm whether the unit they have will suit your car.
