restoring a RPM Ultra Molded 10T

Post by Twiceblown351 »

Well the Rpm 10T that was for sale on here. The frist guy fell through. So I pick it up. And what a nice truck it is.

I wash and the part and it came up like new. the only thing is the 2 holes that some one drilled in it. but there not that bad. Some if the parts were wrong but i had them allready. I still have a little work left. And should be done tonight.

It had the wrong front bulkhead, rear shock tower. And body mounts, And came with a new battery cover. And rear hubs with bearing and rear arm monts. I got some new rims for it to.


But here some pis of it.

just as a heads up, the front tower is actually a "worlds", not a truck. might be able to get a couple bucks for it if you have a truck one laying around you could use.

Yea but dosn't it have to have the other hole drilled in it to mont to the chassis brace? I have a would towwer NIP and thought it looked just like it.

And one know anything about the body. It made by S&K.

ya, you'd have to drill to holes in the 10t tower.

it's an s&k AIRS body. they had a tunnel that ran from the winshield to direct air to the motor.

From that angle the body looks like a truck/funny car hybrid. Very cool.

I have 2 RPM buggies, one complete, the other is missing some pieces. I really hope to find an RPM 10t soon.

Looks good.

Thank you. Its done I.ll try to put some pic up tonight.

I need some help with the rear shocks.

I had blue spring and not shore what oil. And I put 25w oil in them and it couldn't even hold it self up. so I change it to gold springs and 40w with RPM pistons and now its to much spring and too bouncy. I set them up like I have my other 10T tub truck but it all wrong. Should I put 55w oil in them. and a stronger spring?? And the spring collar is slid way to far down the shock. But thats what its taking to hold it up.

Memories.. I used to run that style body on my RPM 10T. I dyed all the parts black though, and I have no idea where it went years ago.

I always ran green springs and 35wt oil ( mix of half 30 and half 40) with stock pistons.

I got that body when it first camre out, it was something different. I cant find it but I supposed to go through some stuff my friend has I used to race with, I hope it is there.

Don't have a link to what "exactly" that is, but half and half oil mixes do not work out like that.

Well I am not sure what it works out to but it worked for me.

I having been holding back for a a week or so but it is time to ask. Why do you always post a negitive comment ? :?

Hes Not. And its the truth Oils don't mix that way. 1/2 30w and 1/2 40w don't make 35w.

The oil dosn't make the springs any stronger ether. I just looked. the red spring i have on the front are stronger then the gold ones on the rear. Which is why its pushing so bad. The spring that are on it were on there when I bought it. So i have some tuning to do. I'll just have to buy a pack of spring and some oil and play with it to get it right.

the RPM 10t is a lot lighter the my 10T pan truck. so the same set up not going to work. It just would be nice if I had a starting place.

Again I did not know about mixing the oil, But as I stated that is what worked for me.

As for the oil changing the spring rate, I agree it will not change the rate of the spring it will only control the damping rate of bound and rebound.
