Bolaxin Injector Tube Remover & Installer Kit for GM 6.6L Duramax 2001-2020 — OEM Tool Replacement, Hardened Machined Steel

Bolaxin Injector Tube Remover & Installer Kit is a complete tool set made to remove and reinstall injector tubes and o-rings on 2001–2020 GM 6.6L Duramax diesel engines.

If you work on Duramax 6.6L engines, this kit replaces factory tools such as J-45910 and mirrors the function of OTC-7222 to let you service injector tubes quickly and safely. The set is machined to withstand shop use, helps protect delicate injector components during removal and installation, and provides straight, controlled seating for o-rings to restore a reliable seal. It’s a practical, purpose-built kit for diesel technicians, home mechanics and fleet service shops that regularly maintain GM Duramax-powered vehicles.

How does this kit protect injector tubes during removal?

The tools are shaped to engage the tube assembly without bending or twisting, reducing the risk of damage to the tube or the injector bore. Using the correct tool limits side-loading and preserves the mating surfaces for a better long-term seal.

• Precision-fit pulling fixtures to center force on the tube assembly.
• Hardened metal construction resists deformation under load.
• Reduced risk of scoring the injector boss compared with improvised tools.

Will the kit help when replacing o-rings and resealing the injector area?

Yes—the installer pieces guide the tube into the bore at an even angle so o-rings seat uniformly and are less likely to roll or pinch. Consistent seating improves sealing performance and reduces the chance of oil or compression leaks from a misaligned tube.

• Installation drivers sized for the factory tube geometry.
• Controlled seating avoids over-compression of o-rings.
• Compatibility with OEM-style o-rings for 2001–2020 6.6L Duramax engines.

Is this tool set durable enough for regular shop use?

The kit is manufactured from high-quality materials chosen to withstand repeated use and resist wear in professional environments. Components are machined to maintain fit and alignment over time, giving reliable performance across multiple service cycles.

• Heat-treated metal parts for long service life.
• Precision machining ensures repeatable alignment every use.
• Single-package kit keeps parts organized for daily workflow.

Which model years and engines does it fit, and does it replace specific OEM tools?

This set is designed for GM 6.6L Duramax diesel engines from 2001 through 2020 and functions as a replacement for tools like J-45910 and aftermarket equivalents such as OTC-7222.
