WP AER 48 Spring Conversion Kit

  • Sale
  • Regular price $807.00

During the development of the WP AER 48 WP benchmarked the AER system with conventional systems, which use conventional coil springs.

Both systems showed different advantages, which were each favored by different riders. In order to provide both options, WP has decided to also provide a retrofitting kit, which simply allows rebuilding the AER 48 to a conventional coil spring system.

With this kit, the AER 48 air cartridge on the air fork leg is replaced with a spring cartridge kit. The damping side remains unchanged.


  • Same performance as the AER 48, but uses a conventional coil spring system
  • Newest technology paired with traditional concept
  • Lightweight construction
  • High-quality original WP Motorsports product

The AER 48 Spring Kit is available for all WP AER systems for the 2016 KTM SX models.
