• Blade Pitch Stability — A correctly functioning rocker block maintains consistent blade angle response across the full pitch range, supporting an even, controlled finish pass on concrete slabs.
• Verified Part Number — Listed under Multiquip part number 2078, making it straightforward to cross-reference against your machine's parts manual before ordering.

The rocker block is a pivot component within the trowel head assembly that translates pitch control inputs into precise blade angle adjustments. On hydrostatic ride-on trowels like the HTX and STX series, accurate blade pitch is critical — even minor wear or damage to the rocker block can result in uneven blade loading, inconsistent surface finishing, and accelerated wear on surrounding pitch-control components. Replacing a worn rocker block restores the mechanical linkage to its intended geometry, allowing the operator to achieve a flat, well-finished concrete surface with full control over blade angle throughout the finishing cycle.
