Grind Blox! AKA Blocks.One fixed piece that bolts under your trucks. It's super easy to install and comes with flatter cushions if you need extra space for Grind Trucks! Designed and produced by the infamous Disco Steward, these will help you stall with confidence and slide for days. We can help you decide which size to get, by using a great guide the Disco has made - let us know the angle of your kingpins (10, 15, 45) and either the axle spread or the distance between the kingpins at the base plate. Here's the link to the Disco Blox size chart for your reference. If you have the stock Moxi plate it's called the Thrust plate in the size guide. Your plate size is in the middle of your plate. Sounds confusing? We know about all the plates on the market, call us and we can talk you through getting the right size! These Grind Blox run 40mm from coping to kingpin nut, so they're deeper. This suits skates with big wheels and grind trucks! If you're looking for a 'shallower' grind block, check out the Low Rider version here (30mm). At Bayside we try to keep something in stock in each size, usually in black, but if there are a particular model and size you need definitely let us know and we'll get it made. Compatibility varies between different brands and plate models, so if you're unsure of whether or not they'll fit onto your plates, please contact us with your plate model and size. For Powerdyne Revenge, Reactor and Rival plates, you'll need to purchase the Radius Kingpin Kit due to the taper on the kingpins.
