speedloader Posted June 26, 2019 Share Posted June 26, 2019 Hello,Is anyone in here running the RPM arms and Innovative RC big bore shocks on their HPI Baja?I cant figure out why there isnt space for the big bore shocks in the front upper arm.I have attached a picture of the arms with the standard shock and as you can see it isnt in the centre of the front upper arm.But with the RPM arms, no caster adjustment is possible.

Ninetiesbeard Posted June 26, 2019 Share Posted June 26, 2019 Do they not have those weird little plastic spacers on the bottom eyelet? to allow fore and aft movement? If so could they be modified? Quote Link to comment Share on other sites More sharing options...

If so could they be modified? There are small spacers in the lower front arm. But these i need one on each side of the shock mounting point so the shock is centered in the lower front arm. However the stock upper arms has small plastic spacers for caster adjustment, but the RPM upper front arms do not allow these spacers and therefore No caster adjustment.

Ninetiesbeard Posted June 26, 2019 Share Posted June 26, 2019 Is there a way that you could adjust the bottom eyelet position using the spacers ? maybe they are a different size each side and you accidently stuck them in backwards? i know ive done that before with similar things Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted June 26, 2019 Share Posted June 26, 2019 Where are they mounted at the top? Sometimes they need mounting differently depending on shock tower/brace. Quote Link to comment Share on other sites More sharing options...
.AJ. Posted June 27, 2019 Share Posted June 27, 2019 I ran the same shocks with RPM arms with no problems Quote Link to comment Share on other sites More sharing options...
speedloader Posted June 27, 2019 Author Share Posted June 27, 2019 Well the stock shocks wont centre perfectly no matter what i do. There is only one spacer (not 2 as i earlier wrote) at the bottom mounting point. I have to keep the spacer at the rear of mounting point in the lower arm. Elsewise the shock will touch the lower front arm. But i think there is space enough for the big bore shocks now. But it surely will be a tight fit.

speedloader Posted June 27, 2019 Author Share Posted June 27, 2019 The bigbore shocks have a longer link at the bottom of the shock and therefore the clearance is better at lower front arm. Quote Link to comment Share on other sites More sharing options...

Sometimes they need mounting differently depending on shock tower/brace. They are mounted in a turtle racing shock tower combo. Only one mounting position.

I've seen people mount them wrong on all types of mounts, so it was worth asking. Quote Link to comment Share on other sites More sharing options...

Sure no problem.😀 There are no spacers in this tower. Quote Link to comment Share on other sites More sharing options...

spents Posted July 2, 2019 Share Posted July 2, 2019 as JA5ON said above mate, contact rob at I-rc, he will help you out if he can, there are various spacers available from I-rc for the big bores, so you may just need different spacers, I have big bores and rpms on my sandrail and they did take a bit of fiddling to get em to clear, the springs are always gonna be very close or catch the screws in the top arms where the top eyelet/ball holder fastens as well, and you will never get em central in the arms, they just need a little trial and error and thought and you will get em to clear 1 Quote Link to comment Share on other sites More sharing options...
spents Posted July 2, 2019 Share Posted July 2, 2019 heres a few pics of how mine are on my sand rail mate, more scope for adjustment on a rail though, , , , 2 1 Quote Link to comment Share on other sites More sharing options...
