For all the gram counters out there. A 88-92 Quadracer LT250R sprocket hub is aluminum and fits the z axle. You just have to use Quadracer sprockets as the bolt patterns different.

this is awsome if the offset is the same. will it line up? have you done this?

My sprocket bolts came loose and F-ed my hub all up and in the process of waiting for my new one to arrive I found one from my old quadracer and slid it on. Although the sprocket bolt pattern is different I held the sprocket up and it appeared the chain would track straight and true.


I still have the hub if your interested. The only problem with these hubs is being aluminum the bolt holes can stretch so proper torque is a MUST.

The LTZ sprocket hub is aluminum, too... It's stronger than the LT 250R sprocket hub for a reason - 4 stroke torque. Ever see 4 stroke guys run aluminum rear chainrings? Not often. Know why? They won't stand up to the torque.

If people want to switch over to this thing, then have at it. If it was a worth-while replacement, it would have been run by the factory guys that were racing LTZs...

Mine are steel. Both on my old 04 LTZ and my current 03 KFX. Even the new one I bought is Steel. I agree about the possibility of them stretching, thats why I'm not using it.
