Hoyt HBX Gen4 Module

The engine of the RX-9 and AX-2 is the HBX Gen 4 Cam System. As the name implies, this is the 4th iteration of Hoyt's popular HBX cam system.

Along with many other design improvements, the HBX cam system has changed the game when it comes to smooth draw, silent shots and overall performance of Hoyt bows over the past few years.

The Gen 4 HBX cam preserved the smooth shot experience of previous HBX cams while increasing speed in many of the draw length positions across the draw length range.

This is done through a new module system that increases efficiency in each inch of draw length instead of optimising the module for the longest draw lengths and sacrificing performance at the shorter draw lengths.

It's easier to design a cam this way because you have less parts (less modules), but Hoyt didn't take the easy way with the Gen 4. Hoyt designed 5 modules to optimise performance for every inch of draw length range. For example, the RX-9 Ultra at 29 inches gained 19 fps over its predecessor, the RX-8 Ultra. The modules are numbered 5, 4, 3, 2 and 1 with module 5 being for the longest inch of draw length available on a given model and module 1 being the shortest draw length.

Each module covers ¾" of an inch in draw length range. For example, the number 5 module on the RX-9 maxes out at 30 inches and adjusts down to 29.25. The number 4 module will pick up at 29 inches and adjusts down to 28.25 and so on.

Additionally, the Gen4 has adjustable draw let-off positions so you can choose between 75%, 80% or 85% let-off by adjusting the position of the mod foot, which is easily done by removing one screw.

You can also choose from a hard wall or extra hard wall feeling at full draw by swapping the mod feet from top to bottom. Your bow will come with the feet in the extra hard wall position and if you want to try the hard wall position, you simply move the mod foot on the top cam to the bottom cam and the mod foot on the bottom cam to the top cam.

This is the most adjustable hunting cam ever to give you your most comfortable, best fitting bow ever.

Gen 4 also improves tuning and centre shot with the addition of a split harness to balance the load from the cables on both sides of the cam. This reduces cable induced torque and cam lean, improving tuning and centre shot consistency.
