The SPOOLOGIC SL-100-062 is a brand new, direct-fit factory replacement turbocharger for 2024-2026 6.6L Duramax L5P trucks. Built on the updated 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 2024-2026 L5P owner who needs to replace a worn-out, damaged, or failed factory unit and wants to put the truck back to stock performance. The 2024+ L5P uses an updated turbocharger with revised wheel sizing and a different turbine wheel design from the 2017-2023 unit — the two are not interchangeable, and the SL-100-062 is built to the correct 2024+ specification. No tuning required, no supporting modifications needed — it bolts on and the truck drives the way GM built it.

Updated 2024-2026 Platform — Brand New, Ready to Bolt In

The SL-100-062 is built to the exact updated factory specification the 2024-2026 L5P was engineered around. Same updated 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 2024+ L5P to its factory rating of 470 hp / 975 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

61.5/82mm Compressor Wheel

Factory-spec compressor wheel sized to match the 2024+ L5P’s updated 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: 61.5mm
• Exducer diameter: 82mm
• Material: aluminum compressor wheel

64/70.1mm 10-Blade Turbine Wheel

Updated 10-blade turbine wheel matched to the 2024+ compressor. The 10-blade design and revised sizing are specific to the 2024-2026 L5P application — this is not the same turbine wheel used on the 2017-2023 L5P.

• Turbine inducer: 64mm
• Turbine exducer: 70.1mm
• Blade count: 10

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.
