New from JConcepts are these artfully crafted C and D blocks. Available in either blue or black these precision pieces accept the stock Associated pills for precise setup changes and each piece is laser etched with the JConcepts logo as well as the toe in amount (for the C blocks). The mid mounted C block weighs in at 3.8g lighter than stock while the rear mounted D blocks are 3.3g lighter. Each piece is sold separately and attaches using the stock hardware.
