MAXX Model's 2026 threaded front housing replaces the engine's stock part with a CNC machined aluminium housing that a MAXX hop up chamber screws directly onto. Locking the two together helps keep the nozzle, chamber and bucking lined up, for a consistent air seal and reliable feeding.\u003c\/p\u003e\n\u003cp\u003eIt's made in seven versions, so choose the one that matches your engine. Fitting is simple: unscrew the stock front housing from the engine, screw the MAXX housing on in its place, then rotate the engine to line up the air-line connection. MAXX's instructions cover their 2026 hop up chambers and their earlier chambers, using brass spacers to set the depth.\u003c\/p\u003e\n\u003ch3\u003eVersions\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePolarStar F2 (MX-HPA004PF2)\u003c\/li\u003e\n\u003cli\u003ePolarStar Jack (MX-HPA004PJK)\u003c\/li\u003e\n\u003cli\u003ePolarStar Kythera (MX-HPA004PKA)\u003c\/li\u003e\n\u003cli\u003eWolverine Inferno Gen2, AEG (MX-HPA004WI2)\u003c\/li\u003e\n\u003cli\u003eWolverine Inferno XTS, AEG (MX-HPA004WIX)\u003c\/li\u003e\n\u003cli\u003eWolverine Inferno Gen2, MTW (MX-HPA005WI2)\u003c\/li\u003e\n\u003cli\u003eWolverine Inferno XTS, MTW (MX-HPA005WIX)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe PolarStar and Wolverine AEG versions are for engines fitted in a V2\/V3 AEG gearbox.
