Help! Suspension dog bone questions

Okay, going to replace the dog bones (suspension rods) on the KDx250. Is there a better than stock unit to replace them with? Stock there is a listing for a T6 = optional and a T10 stock. The later 94 KDX only list the T10.

Anyone know the differences? Also the KDX for the 91 year list a different part for that. I dont know a lot about the linkage beyond a general knowledge, but if changing to something aftermarket or different length would greatly help out the rear suspension, I am all for it.

Thanks!

Devol has nothing for the bike listed.

Talking to a mechanic that new the older first gen KX perimeter frame and suspension pretty well, he said the T=6 will be shorter rods, but raise the rear of the bike to increase the suspension travel and help turning. Makes sense on the turning-- same thing honda did with the 03 CRF450, raised the rear end to change the rake of the bike and increase turning.

See how it all goes. I am hoping to get the parts at the end of the week.
