if you can get a Pro4 for $175..that is cheap. I would go that route. and upgrade to the Spec parts.
basically all you'll need is:

+new upper deck (as shown -- more lateral flex, same fore to aft stiffness, reduced chance of tweaking on impacts, with cone washers and o-rings over the steering posts as used by Hara)
+Delrin diff out drives
+new 1 piece aluminum rear input shaft (combines spur adapter and shaft, with solid pins, much more rigid gear mounting, different than Japanese spec parts)
+Spool
+full range of pivot block spacers to adjust block heights
+0, 2.0, 2.5 and 3.0 degree pivot blocks

Thanks for that zombies, it looks as though it'll be cheaper to buy the whole set, are they going to be significantly better or not?

I know the Schumacher one are for the general ball cups problem that the stock HPI has....just not sure ppl use that for the lower SHOCK mount as well...

Beside, the stock HPI ball stud are too tall........that won't work.

yet to recieve mine..so I couldn't compare. I know the low-friction o-rings and new bladder work great... the o-rings are smooth as butter..

i'm almost out of diff lube (2nd tub, white lid), what are some other alternatives that work just as well?

teflon spray? graphite powder? boil them? soak in wd40? do nothing to them?

sorry, I should of said this is for the bevel gears, not the diff balls

looking to try anything really, as long as it will keep the drivetrain nice and free...

axel

boil them is good softens them up so they won't crack easier. But when hitting those boards really hard... boil or no boil they will probaly break. Hopes this helps

I treat all gears with CRC Teflon Dry-glide then use normal grease as well ( ceramic Grease )
Some people here use dry glide only. Dry glide leaves the gears very slippery to the touch.

Hope this helps

I need help reducing understeer. Whenever i make hard rights i don't get the response i want as i do making left turns.

is your chassis evenly balanced? the weight of your cells along the left might be assisting your turn in....

other than that check the usual are all equal, camber/toe, ride heights, droop, steering endpoints, etc

axel

everything seems alright to me. It isn't a huge problem, but it is still noticable. I find myself holding my wheel all the way to the right just to make a wide right.
