I'm looking for any info about modifications necessary to mount a 2005 440 mxz x track,121x15x1.75"paddles with 3" drivers onto a 2002 500mxz with std 121x15x.875" track. Will the drivers on the 500 mxz match the 440mxzx track and is there enough clearance for the 1.75"paddles in the tunnel?? Thanks for any help, Tapiolaboyga

yea it should work... only thing is that it will be pretty tight under there.... and you will probably have to gear down to make the track spin better, without doing this it will be hard to get the power to the track.. i put a 1.5 intense on my sled and i geared it down to 21/44

if that helps any?

What do you mean by 3"(3" pitch) drivers.. looking on Hlsm.com the drivers on a 2005 race sled.. look to be standard 2.52 pitch 9 lug extros unless I am mistaken. For if it was a 3.0 pitch track you would have to change drivers.. but it looks to be a 2.52 pitch.. based on the drivers call out... they are 9 lug..and 9 lug 3" pitch drivers are huge.

Anyway, should fit fine.... might want to gear down a bit..

You can fit a 2" lug in there, I have 2" in three zx sleds. And the 02 sleds have more clearance then the 99 thru 01 zx as they rolled the chain case back about 5/8".. so the 1.75" obviously would fit easily as I have a 99 zx and an 01 xz with 2" lugs on them. I am assuming that you are not studding the 1.75" track.. that might cause some problems..
