Description

S&S Diesel LMM Duramax Injectors (2007.5-2010) are available new or remanufactured Bosch bodies. They are calibrated on genuine Bosch equipment to OE standards (Viscor SAE-J967, 40°C, 100 bar). Proprietary nozzle honing ensures clean, consistent holes, with nozzles flow-matched to 1% variance per set. Injectors are flow-matched to 3% variance per set (excluding TorqueMaster). Each injector build spec is custom-matched to the nozzle flow rate. Injectors from 250% (3200 cc/min) and up feature internal body modifications for improved injection rate shape, addressing slower open/closing times at increased nozzle flow. Core returns are required; a $150 charge applies if no core is returned.
