Description

The 0986435521SE-IIS is a remanufactured stock-replacement injector for the 2006-2007 6.6L LBZ Duramax. When factory LBZ injectors start drifting — rough idle, balance-rate codes across cylinders, white smoke, or visible fuel weep — this is the drop-in OEM-spec replacement. Built in-house from genuine Bosch cores with brand-new Bosch nozzles and balanced to a tighter tolerance than factory. Sold individually; most LBZ trucks need a full set of 8 when they're replacing injectors.

Each injector is fully disassembled and rebuilt with brand-new Bosch internals — nozzles, valves, and hardware — not just cleaned-up old parts. Industrial Injection balances each injector to a tighter flow tolerance than the original OEM spec, which is what produces smoother idle and more consistent fuel trim after install. Every finished injector is run on a Bosch OEM test stand before it leaves the line.

Each injector ships with new copper crush washers and O-rings for install — both are one-time-use parts.

Features

  • Direct OE Replacement for 2006-2007 6.6L LBZ Duramax
  • Brand-New Bosch Internals — Nozzles, Valves, Hardware All New

  • Sold Individually — Order Qty 8 for a Complete Set

Notes

  • Most LBZ trucks need all 8 injectors replaced at once — the high-pressure fuel system is balanced across all cylinders. Mixing new and old injectors causes balance-rate codes.
  • Plan on replacing the copper crush washer and O-rings (both included) — one-time-use parts.
  • Cores must be returned within 45 days for the $170 core charge to be refunded.
