+1, the kit doesn't come with any, but I always have some

quick question? after i built my kit i noticed i had 2 or 4 e-clips left over from building the shocks? is that normal? i have no problems with the shocks or car at all and have looked over the shocks and everything... Everything seems fine just curious if that is normal?

I think a few extra e clips in normal, its when you have extra screws that I start to worry, HAHA.

On a side note, jumping back to the top shaft discussion, has anyone tried the X-Factory top shaft? Looks like it mat be a different material. Wonder if it lasts a little longer?

Sorry, still need a little more clarification.

Is the limiter the "nylon spacer" (part 4187) that the B4.2 manual says is installed on the shock shaft just underneath the piston?

Yes, it's on page 12 of the manual at the bottom

MIP top shaft is dialed. Weighs 4 grams vs 12 grams in stock shaft

I also highly recommend the AVID clutch over the VTS

i haven't been on here since i suggested mip top shafts and avid slippers to reduce your rotating mass and run 69/35 gearing.....
glad to see some of you have listened...
the rest will catch on soon enough!

PS These tricks helped me to a 15th overall at the Australian titles last weekend in 17.5 2wd Buggy....they work.- First ever National event by the way.....

I have. Night and day difference, not quite. It last about as long as the stock one, but allegedly it runs more true. It worked just as well as the OE part until it needs to be regreased.



I actually ran stock buggy the other day, and it was a lot of fun. I just throw on the regular 2-plate slipper and run it. I don't think I even botherd checking it, but I was 2 laps up on the regular 17.5 pace. I miss mod =(

Yes. You need a special shock shaft to accommodate them.

Only Cav has the "special" shock shafts :sneaky:

If you don't have a proper tool set, get one. Will save you many headaches and lots of time.

+1 or have friends with the proper tool sets:ha:

Also get some green slime for the shock build and thread lock (I use blue).

+1 green slime and blue thread lock

I have 4 extra from my build this week.


The reduction of rotational mass is something I ponder a lot! :deathstar

+1 for the MIP and I use the V2 slipper. I run it in Stock buggy,truck,and SC. Definately worth the money.

The avid triad is slightly lighter again, I think it got -7g on the vts.

Do you use the precision racing systems pinion gears?
They are coated alloy and have lightning holes... I just weighed my new
36t it comes in @ 2.6g & FYI a 34t Robinson racing steel item is 7.4g !!

Easy savings, massive gains

chevmaro 04-12-2013 07:59 AM

MIP Topshaft -8
Avid Triad -7
Precision Pinion - 4.8
Total -19.8 Grams

Might have to add weight. Really want to try this on my stock buggy.

Wildcat1971 04-12-2013 08:17 AM

I am lucky in that dropping weight just seems to hurt the handling of the car. And clearing the jumps is cake in 17.5. I could see how at the local indoor track dropping weight could help. There are 3 jumps that it might help with and of course quicker corning in the infield. If I was competitive I would spend the money. But I am just lap traffic, lol. So no point.
