Rolls-Royce Cullinan Series II Conversion Kits Are Now A Thing — Here's What We Know

It usually takes the aftermarket about five minutes to react when a luxury flagship gets a facelift, and the Rolls-Royce Cullinan has proven no exception. Ever since the 2025 Cullinan Series II arrived with its dramatically reworked face, owners of the original 2018-2024 car have been left looking at a familiar problem: love the car you have, or covet the one you don't. A niche corner of the tuning world has spotted the opportunity - and one of the more complete solutions we've come across lately comes from Hong Kong-based outfit Own Silent International Limited.

The company recently shared a Series I to Series II conversion on its Instagram page (@ownsilent.international), complete with before-and-after shots of a first-generation Cullinan wearing the full facelift treatment. Scrolling through the images, the transformation is genuinely hard to fault from a distance - though, as with any aftermarket conversion, how close it gets to factory standards is something only an in-person inspection would settle.

What The Kit Covers

Going by the listing, this is a 1:1 OEM-style kit that touches essentially every exterior panel and component that changed between the two generations. Up front: the radiator grille and its garnish, the surround frame, a Spirit of Ecstasy emblem cover and base, the complete bumper assembly with corner covers and air grilles, moulding trims, and the headlight assemblies.

Around back, there's a full bumper assembly, corner covers, exhaust finishers, trim panels, and new taillights.

That front-end work matters, because that's where Rolls-Royce concentrated the Series II update - the now-illuminated Pantheon grille, the new LED daytime running light signature, and a redesigned bumper give the 2025 car a noticeably bolder face.

The detail that caught our eye, though, is the non-drill mounting bracket system. If it works as advertised, the whole conversion is reversible - no small thing for anyone thinking about long-term resale or the option of returning the car to stock one day.

Why Owners Bother

The maths is fairly simple. The 2025 Series II is the biggest visual update the Cullinan has had since its 2018 debut, and buying one means a serious outlay plus, in many markets, a wait. For an owner who's perfectly happy with their existing car - its spec, its bespoke interior, its history - a cosmetic conversion is the quicker, cheaper route to the current look.

It's not a decision without trade-offs, mind. Conversions live in a grey area for purists and can colour how collectors value a car down the line. There's also the practical homework: lighting assemblies need to meet local road regulations, and it's worth checking how modifications sit with insurance and any remaining warranty. Pricing for this kit isn't published either, so a direct inquiry is the only way to judge the value equation.

Who Is Own Silent?

Founded in 2019 and headquartered in Hong Kong, Own Silent has carved out a niche in aftermarket parts for luxury marques. A browse through its catalogue and social channels turns up conversion body kits, carbon-ceramic brake kits, forged wheels, and a long list of interior and exterior tuning components for the likes of Rolls-Royce, Bentley, Porsche, and Audi.

The company carries a 4-star rating on Trustpilot from a modest number of reviews - most praising product quality and pricing, with at least one grumble about delivery times.

Whether a facelift conversion is worth it will always come down to the individual owner. But the fact that a kit this comprehensive exists at all says something about how quickly the aftermarket now mirrors even Goodwood's design updates.
