If you own or manage a Citroën Relay, Fiat Ducato, or Peugeot Boxer from 2006 onwards—especially one converted into a campervan, used as an ambulance, or operating as part of a fleet delivery service—you may already know that your air suspension setup differs from standard van models.
The good news? Polybush has you covered.
Whether you’re trying to eliminate annoying knocks and poor handling from worn bushes or save on costly full component replacements, our polyurethane air suspension bushes are the perfect solution.
These vehicles often come equipped with factory or aftermarket air suspension systems to enhance ride comfort and handling under varying loads. However, this means they don’t use the same bush sizes or configurations as standard steel-sprung vans.
Because of this, many Citroën Relay, Fiat Ducato, and Peugeot Boxer owners struggle to find the right replacement bushes—especially if their vehicle was professionally converted for medical, leisure or commercial use.
To help you identify the exact Polybush part you need, we’ve created a clear PDF guide with dimensions and images of each air suspension bush we offer for these platforms. All you need to do is:
Measure your existing bushes or mounting points
Compare the dimensions with our guide

Whether you run a single campervan or a fleet of front-line ambulances, rubber just doesn’t last in high-load, high-use scenarios. Here’s why Polybush is the smarter choice:
Longer Lifespan – Polyurethane is resistant to wear, oils, UV, road salt, and varying conditions.
No Perishing or Cracking – Unlike rubber, Polybush doesn’t degrade .
Improved Stability – Tighter tolerances give better ride control and reduced body roll.
Cost-Efficient – Replace just the failed bushes rather than complete arms or air bag mounts.
One of the UK’s regional ambulance services contacted us after struggling to source replacements for the failed air suspension bushes on their Fiat Ducato-based ambulances. The main dealer advised them to replace the entire mounting assembly, at a significant cost per vehicle.
After working with their maintenance team and reviewing measurements from our guide, we supplied only the specific polyurethane bushes that had worn—saving them from scrapping perfectly serviceable components.
Result? Thousands of pounds saved, less vehicle downtime, and longer-lasting performance.
If your vehicle falls into one of the following categories, this applies to you:
✅ Motorhome or Camper Conversion with air suspension
✅ Ambulance or Patient Transport Service using Relay, Ducato or Boxer chassis
✅ Delivery Fleet Vans with air-ride suspension kits fitted
✅ Any modified suspension layout not using standard steel springs
Don’t gamble on generic parts or complete assemblies. With Polybush, you get precision-fit polyurethane bushes that are made in the UK and built to outperform rubber.
Whether you’re a fleet manager, ambulance workshop, campervan owner or converter, our experienced team can guide you to the right solution.
