Allison HD 4000 units have large dampers that require special equipment to complete the bonding process. Sonnax piston bonding service PB-500 is available for these units, allowing shops to forego the expense of tooling up to bond friction to HD 4000 dampers. Friction mounting area is resurfaced if necessary and strict processes are adhered to throughout the bonding operation for superior performance results.
