Bingo Airsoftworks G&G/Army L85 Gearbox Replacement Kit

The Bingo Airsoftworks G&G/Army L85 HPA Engine Gearbox Replacement Kit is now available. The L85 HPA kit allows you to easily upgrade your G&G or Army L85 to use either the PolarStar Fusion Engine or the Wolverine SMP (it will also work with the PolarStar F1 and Wolverine Hydra, when available). The kit includes everything needed to convert your L85. You only need to hook it up to your air rig and tank and you are ready to go.

There are two versions of the kit. One version is for the PolarStar Fusion Engine (the V2 upper cylinder), and one version for the Wolverine SMP (Wolverine Hydra and PolarStar F1). Also there are different trigger switch brackets for the G&G L85 and Army L85.

It’s also possible to purchase the chassis and trigger board, so you can install your existing PolarStar or Wolverine HPA Engine.

The L85 Gearbox Replacement kit is available for $450 USD, free shipping (US) (for International customers, additional shipping will be billed separately)

  1. A few vip questions here seeing that this will be my first polarstar system what hose , tank and regulator should i use with my army l85 and also what molle pouch would it fit in for nice 3hour runs but be low profile.

    • I would recommend using the Redline SFR or the Wolverine Storm air rigs. I recommend using a Ninja 90/4500 tank, but smaller ones will also work. A hydration bladder carrier holds the air tank nicely, and still provides room to have the water carrier too.
