what kind of riding do you do? a extra 10 is alot better for most aplications than a X-12, there slower and are not a agresive suspension.


oh ya welcome to the site!

Check out this topic. I posted the mounting locations there, and there is a lot of additional info.

Based on my findings over the past few weekends when I began my Xtra-12 front and rear swap into my '89 indy 650, I'd suggest not swapping in the X12 suspension. I found that mounting the front hole in your tunnel would require heavy modifications and wouldn't seem worth the effort. I'd also suggest an X10 skid for the rear, as you wouldn't need to change the front suspension to match. I ended up purchasing an X12 chassis from a 95 XLT SP and now have to switch everything over. It should be sweet in the end, but its much, much more of a project than I had expected. Just my .02. If you have any more questions or details let me know and I can post them. I know first hand.

Based on your second post you will want to go with the xtra-10 skid, besides, it's probably an easier project anyway. There is step step instructions for the xtra-10 conversion right here on SF.

Yes, I would use an X10 rear suspension and just swap in some FOX front shocks and maybe use the plastic ski spindles for an extra inch in height for the front. It'd handle tons better and be much more agressive.

Or, if your very capable attempt maybe an EDGE rear swap. Some have done it, but I dont know much about these suspensions. I'd assume they are more agressive than even the X10 though. If you need anymore help, dont be afraid to ask!
