eX-Change Electronic Shock Absorbers

Teknik eX-CHANGE Shock Series

eX-CHANGE Shock Series

When you need to replace your BMW ESA shock absorber you don't want to pay for a complete coilover unit - if you can find one - they're expensive! These eX-Change shocks are designed to replace only the stock electronically controlled damper in the middle, reusing the stock spring & electronic preload adjuster (if fitted). Completely plug & play, with no loss of advanced features or weird error messages on the screen - bolting to the factory mounts & plugging directly into the OEM electrical wiring loom. See the ESA changeover process on the official TracTive video.

Replacement ESA dampers that retain factory features and fitment

  • Plug & play replacement for BMW electronically controlled dampers
  • Reuses stock spring and electronic preload adjuster where applicable
  • Updated Dynamic ESA motors for wider tuning ranges and faster response
  • Fully rebuildable, cold-forged 6082 aluminium shock body with external reservoir
  • Multiple spring rates available to suit all rider weights

Recommended Pairings

Consider matching your upgrade with Suspension Tools for correct setup and servicing.

eX-CHANGE Shock Series

When you need to replace your BMW ESA shock absorber you don't want to pay for a complete coilover unit - if you can find one - they're expensive! These eX-Change shocks are designed to replace only the stock electronically controlled damper in the middle, reusing the stock spring & electronic preload adjuster (if fitted). Completely plug & play, with no loss of advanced features or weird error messages on the screen - bolting to the factory mounts & plugging directly into the OEM electrical wiring loom. See the ESA changeover process on the official TracTive video.

Replacement ESA dampers that retain factory features and fitment

  • Plug & play replacement for BMW electronically controlled dampers
  • Reuses stock spring and electronic preload adjuster where applicable
  • Updated Dynamic ESA motors for wider tuning ranges and faster response
  • Fully rebuildable, cold-forged 6082 aluminium shock body with external reservoir
  • Multiple spring rates available to suit all rider weights

Recommended Pairings

Consider matching your upgrade with Suspension Tools for correct setup and servicing.
