The Zero 10x rear stock rear suspension is spring only. No dampening. The problem is the bouncy, unstable feel when riding over bumps especially broken or uneven pavement while turning. I checked around for shocks and no one has them in stock except AliExpress.

In this video, I showed how I remove the stock rear shock and install the new EXA291R shock that has a rebound and preload adjustment. I also did some test to verify the rebound adjustment actually works. The removal and installation was not difficult. The most difficult part was trying to split the suspension arm halves to get the rear shock out. It took maybe 1 hour worth of work. You will need metric socket hex and Allen keys.

I highly recommend this upgrade to anyone with a Zero 10x. The upgrade is well worth it. The ride is much smoother, confident inspiring and definitely more stable. Feels like a different, more refined scooter!

The shock:
KS EXA291R rear shock. 165mm eye to eye. 1500 Lb/inch spring rate.
