1800 kg Knott Spring Axle – OEM Replacement Trailer Axle for European Caravans

This spring axle is an 1800 kg Knott-compatible leaf spring axle engineered for European caravans, campers, lightweight trailers and small touring vehicles. Built to OEM replacement standards, this spring axle delivers reliable load-bearing performance and straightforward maintenance for trailer builders and caravan manufacturers across Europe.

Featuring high-strength steel construction with precision-welded spring seats, this 1800 kg axle unit is designed to bolt directly to standard European caravan and camper chassis. The traditional leaf spring suspension provides consistent load distribution and proven durability, making it a cost-effective alternative to complex independent suspension systems for lightweight and mid-duty applications.

  • Axle Type: Leaf spring axle (straight axle)
  • Brand Compatibility: Knott and standard European trailer chassis
  • Suspension: Leaf spring with standard spring seat spacing
  • Application: European caravans, campers and lightweight trailers
  • Brake Options: Compatible with 200×50 or 250×40 overrun mechanical brake drums
  • Construction: High-strength steel tube with welded spring perches
  • Finish: Powder coated or painted for European road conditions

Applications

  • Camping trailers and pop-up campers

Why Choose This Knott Spring Axle
