Metric shocks with the same eye-to-eye length are physically the same shock, no matter what the stroke is. For example, a 230x60 shock is the same as a 230x65 shock, but the 230x60 just has a 5mm spacer installed to reduce the stroke by 5mm. Ohlins sells their shocks in each individual eye-to-eye length and includes the small parts required to change the stroke internally in 2.5mm increments down to a maximum of 7.5mm reduced stroke.

• Ohlins shocks are shipped out in the MAXIMUM stroke length for that size of shock.
• EXAMPLE: If your bike needs a 230x60 shock size, you would purchase the 230 length shock and then install 5mm of stroke spacers to reduce the stroke to 60mm.
  
  

Ohlins shocks are shipped out in the MAXIMUM stroke length for that size of shock.

EXAMPLE: If your bike needs a 230x60 shock size, you would purchase the 230 length shock and then install 5mm of stroke spacers to reduce the stroke to 60mm.

This procedure requires an 8mm Shaft Clamp and Loctite 243.

• To reduce the stroke of your new Ohlins TTX2Air or TTX1Air, please follow this video: How to change stroke on an Öhlins TTXAir rear shock
• There is not a stroke-reduction-specific workshop manual, but the removal of the end-eye is listed in the 100 hour air can service guide: Ohlins TTX Air 100 Hour Air Sleeve Service

If you are switching from a Fox or Rockshox shock to an Ohlins shock, you can absolutely use your Fox or RockShox mounting hardware in the eyelets of the Ohins shock.

• Fox, RockShox and modern Ohlins shocks (and almost every brand of rear shock) uses an eyelet size of 15mm inner diameter and width of 12.7mm(1/2"). This means you can use any hardware between these brands of shocks, which saves you money from having to purchase new hardware.
• Ohlins and Fox shocks both use poly IGUS bushings which you can easily remove with a small flathead screwdriver.
• RockShox shocks use a metal DU bushing which is pressed into their eyelet. You will remove the poly IGUS bushings from your Ohlins shock, press out the metal DU bushings from the RockShox eyelets using a DU Bushing Removal Tool, and then pressing it into the naked Ohlins eyelet.
