Chimera Adjustable Stretch Extension Blocks - Honda Grom 125 (ALL YEARS)

The Chimera Adjustable Stretch Extension Blocks allow you to stretch any generation of Grom! Stretch your build from 4” to 6.5” (+/- ½” depending on the chain tension adjuster) easily. Made from T-6061 Aluminum, this part slides directly into your swingarm making installation a breeze. Just slide in, bolt to your desired length, and done!

Please note:

• A longer chain will be needed 130L -140L will work!
• For the +22 Grom the OEM axle may be too long, so it may have some slack. You could either run the OEM chain adjuster position plate or purchase axle spools/sliders to correct the slack.
