#1830 Replacement Slider Pucks for SLIDEmoto Mini Sliders
These fit the SLIDEmoto Mini Sliders, like the Honda CRF150R Rear Axle Blocks.
These are machined from UHMW-PE (Ultra High Molecular Weight PolyEthylene), which is a very abrasion resistant plastic with a very low coefficient of friction so it doesn't wear out as fast as other materials like Delrin.
