Zilla hub is 26 spline same as the Z400 or you can also use the LTR450 hubs which are .75 wider and you can use a small spacer.

The hubs pictured are the G-force as mention above for the Z 400 which is a 26 spline axle and I believe they widen it 3 inches over all.

FYI; On some LT250s they re also 26 spline (I believe they are the later years 87+) and some are the 24 spline which are the same as the banshee so I believe you can run Banshee hubs on a 24 spline LT250.

One of you 250 guys want to confirm this?
