When it comes to replacing front suspension bushes on Audi, Volkswagen, Seat, and Skoda models, part numbers like 1K0 407 182, 5Q0 407 182, 1K0 407 182 F, Delphi TD521W, and Febi 24390 are among the most common.
If you’re searching for a long-lasting, easy-fit upgrade for these OEM parts, look no further than the Polybush 44CB – a UK-made polyurethane suspension bush designed for effortless installation and a lifetime of consistent performance.
Redesigned with ease of fitment in mind, the new Top Hat-style 44CB ensures quick, accurate installation and a perfect fit. It’s also the ideal upgrade for vehicles already fitted with Polybush 44EX, delivering improved control and refined handling without sacrificing ride comfort.
If your car’s suspension is still running original rubber wishbone bushes, chances are they’ve begun to crack, perish, or soften over time. Even aftermarket rubber replacements don’t last long when exposed to oil, UV light, and road grime.
Here’s why Polybush 44CB is a smarter, longer-lasting choice:
Manufactured in the UK from a unique automotive-grade polyurethane, Polybush bushes resist oil, fuel, UV, and ageing. They won’t split or degrade like rubber, giving you years of reliable service and sharper handling.
A firmer, precisely engineered material reduces unwanted bushing flex. The result? More consistent wheel alignment, better steering feedback, and tighter control under braking and cornering — without harshness.
Unlike overly hard polyurethane alternatives, Polybush bushes are carefully tuned to retain OE comfort while enhancing stability. Perfect for daily drivers, fast-road use, or vehicles carrying heavier loads.
Polybush bushes are dry-fit – no messy greasing or special compounds required. Once installed, they stay silent and consistent mile after mile, without the need to re-grease like other manufacturers.
Every Polybush product is manufactured in the UK to exacting standards and ISO:9001 certified, ensuring precision fitment, performance, and durability.
The latest 44CB Top Hat-style design makes installation easier than ever. The new profile allows for a smoother, straighter fit into the wishbone with less effort and no specialist tools.
For workshops and home mechanics alike, that means less time on the ramp and a perfect alignment every time.
Already using our Polybush 44EX? The 44CB is the natural next step — offering a compatible, refined upgrade that enhances both comfort and performance.
