The SPOOLOGIC SL-100-060 is a brand new, direct-fit factory replacement turbocharger for 2017-2019 6.6L Duramax L5P trucks. Built on the BorgWarner B2BV-70A VGT platform — the same architecture as your factory turbo — with factory wheel sizing, factory boost characteristics, and full OEM fitment. Every SPOOLOGIC turbo is built brand new — never remanufactured — and backed by a 1-Year Limited Warranty.

This is the right turbo for the L5P owner who needs to replace a worn-out, damaged, or failed factory unit and wants to put the truck back to stock performance. Brand new center section, brand new wheels, brand new bearings — not a heat-cycled remanufactured core with the same miles as the rest of your engine. No tuning required, no supporting modifications needed — it bolts on and the truck drives the way GM built it.

Built to OEM Spec — Brand New, Ready to Bolt In

The SL-100-060 is built to the exact factory specification your truck was engineered around. Same BorgWarner B2BV-70A VGT platform. Same factory wheel sizing. Same factory boost range. Same rotary electric VGT actuator control. The truck spools, drives, tows, and runs exactly the way GM built it — only with a brand new turbocharger instead of a tired, heat-cycled, oil-baked original. This turbo restores the L5P to its factory rating of 445 hp / 910 lb-ft when installed on an unmodified truck running the stock GM calibration. Retains OEM VGT-based exhaust brake function where equipped from the factory.

Upgraded Internals — Standard

Even though this is a stock-replacement turbo, every SPOOLOGIC unit is assembled with upgraded internal components that go beyond a basic factory-style replacement:

• Extreme duty journal bearings — premium bronze-alloy bearings machined to tighter tolerances with improved oil groove geometry, maintaining the precise oil film that keeps the turbo shaft centered at 100,000+ RPM — even under higher heat and shaft loads
• 360-degree thrust bearing — added strength and load capacity over the factory 270-degree bearing, better at handling boost-driven thrust loads
• Step gap seal rings — improved sealing performance, less blow-by past the CHRA
• High-speed VSR balancing — smooth, dependable operation and longer bearing life
• New VGT unison ring and vanes — required for proper variable-geometry operation, installed and ready to run

61.4/84mm Compressor Wheel

Factory-spec compressor wheel sized to match the L5P’s OEM airflow profile. Same dimensions as the unit GM put on the truck from the factory — designed to deliver the same boost response, the same top-end, and the same drivability the truck had on day one.

• Inducer diameter: 61.4mm
• Exducer diameter: 84mm
• Material: aluminum compressor wheel

63.1/70mm 11-Blade Turbine Wheel

Matched to the factory compressor for clean spool, proper boost control through the VGT vane geometry, and the OEM exhaust energy recovery the engine’s calibration is written around.

• Turbine inducer: 63.1mm
• Turbine exducer: 70mm
• Blade count: 11

1-Year Limited Warranty

Every SPOOLOGIC turbocharger is covered by a 1-Year Limited Warranty against defects in materials and workmanship from the date of purchase. Warranty coverage requires that the unit first be shipped back to SPOOLOGIC for inspection. If SPOOLOGIC determines the failure was caused by a defect in materials or workmanship, the turbocharger will be repaired or replaced at SPOOLOGIC’s discretion. Warranty does not cover damage from foreign object debris, oil starvation, contaminated oil, extended oil change intervals, over-boosting, over-fueling, improper installation, use outside the listed fitment, cosmetic wear, coating discoloration, or normal heat cycling marks. Warranty does not cover labor, shipping, towing, downtime, or any other costs outside the turbocharger itself.
