long time.

i can't seem to get the rear of my car stable. it seems as if i don't have much side grip. id be goin into a hairpin and the rear would start hopping and slide out. the other time it happens it when i go over a bump exiting corners under power. the car either swap ends or i have to save it.

i checked my rear shocks and it seems there is binding. somethings when they are fully extended they stick at that length. i then have to pull then puch them in again. it does not happen all the time but is figure when i go into the corner it extends and binds. only mod i did to the shocks was to trim the triangle piece that goes in the bottom of the shock body. i took off half the material on the top of the 'hat' so i could get more droop. they insert it up side down.


my question is What is causing the binding? and could the Yokomo Gurus (u know who u are lol) post a step-by-step build of the shocks?

the shockbody does not have a single inner diameter .. the lower part is slightly bigger than the upper part .. and if u trim the triangle piece, the piston can get into the lower part and bind at the step where the shockbody gets smaller

what rear shocktower do u use?

Better yet order the new Yokomo shock body. It does not need any inserts or tricks to get maximum travel......

I'm not sure but I think this is the part #YS-4SSS-7

A quick way to identify it from the outside is the octagon shape on the top vs round on the original version of the SSS shock body.

thanks, i was thinking about that.








i looked at the shock build in the manual over and over and over. i cant seem to get more than 5.5 on the droop gaug when using the triangle pieces. i really think im doing something wrong cause when i setup my ride height i always seem to have to tread pass half-way on the front shock bodies to get 5mm ride height. im using pink front/ blue rear new white springs.

You might want to look to where you put your hinge pin in the C-hubs. you should be using the lower hole in the C-hub and shimed per instructions. It makes a difference....

Also with the new shock body I can get over 10 mm of ride height if I wanted to so getting maximum uptravel is no issue.....

with the triangle piece in i get shock travel problems with it out i had no issues. i just wanted to build the shock as per manuel. is the triangle piece still used in the new shock bodies?

with the triangle piece intsalled you should be able to make the shocks 62,5mm long and this is enough for almost every downstop you'd like to use

note: when using the provided yokomo droop guage 5 is actually 4 on hudy blocks and every other gauge

cannot explain why but it is that way

so to have real 5mm u have to set 6 on the yok gauge

ok. thanks for all the help. ill rebuild them again lookin at were the piston is in the body through the suspension stroke and see where it binds.


other than that the car is fantastic to drive. using the HB castor blocks, yokomo steering knuckles, cut top deck by the steering post, no rear bulkhead brace, no rear top deck brace. 5 cell/mod

any tips on keeping in the bottom screw on the steering block? im losing screws and HB tophats like crazy! superglue?
