Whether you're an old school carver or new school rail slayer you will want to upgrade to the Matrix II truck system. One of the highlights of this system are the high-rebound MBS “ShockBlocks” which combine the performance of steel coil springs and urethane dampeners into a single piece. Thanks to our carefully formulated SpringThane PU material, MBS ShockBlocks deliver all the rebound you’d ever want from a spring system and all the dampening you’d ever need from urethane system while reducing the weight of your board significantly.  Other features include a flat grinding profile, unbreakable composite top truck, and independent adjustment of toe/heel resistance allowing you to dial in your ride exactly the like you want it.  And all that is on top of the tried and true strength, performance, and precision for which MBS Channel trucks have become symbolic.
