Matrix III Shock Blocks are the lifeblood of the new MBS Matrix III truck system, a key contributor to the unprecedented balance between rebound and stability MBS riders know and love. Our soft (white) polyurethane formula is our softest yet. Mount them in the inside position for the tightest turns imaginable - ideal for lightweight riders or maximum carveability when riding without bindings. In the outside position they offer a great all-around feel - the ideal balance of carveability and stability for average size riders riding with bindings.

Optimized Shock Block shape and formula delivers ideal mix between rebound and stability.

Notes:

• Check our turning resistance chart to see which shockblock hardness is right for you (white, orange, red).

• Only for Matrix III truck system. Not compatible with older style Matrix trucks.
