FAQ

Will these nozzle holders work on Isuzu models outside the 2005‑2010 range?

The sleeves are engineered for the 4HK1 5.2L and 6HK1 7.8L engine families produced between 2005 and 2010. While they may physically fit on earlier or later models, we recommend confirming engine specifications before purchase.

Do I need any special tools to install the sleeves?

Standard injector removal and installation tools are sufficient. The O‑rings are pre‑lubricated and snap into place, simplifying the process.

What warranty does GoTrucky provide?

All nozzle holder kits come with a one‑year limited warranty covering manufacturing defects. Contact our support team with the purchase receipt for assistance.

Can I reuse the O‑rings if I replace the sleeves later?

We recommend using new O‑rings with each installation to ensure optimal sealing performance, as the rubber material can degrade after exposure to fuel and heat.

Are these parts interchangeable with other brands?

Because they match the OEM specifications (Part No. 8976066610), they are interchangeable with any brand that adheres to the same dimensions, but GoTrucky guarantees the highest material quality and machining precision.
