LOL, what did you upgrade it too?
I know the couple we had for demos didn't last long till the diff gears shreded. I think we have 3 of them sitting in a heap on a shelf somewhere collecting dust is anyone is interested in them for parts or to rebuild. Two were tremor trucks and one is a tremor street car.
LMAO! Have you seen that custom truck I made USING the Tremors front end and rear ends? I stabbed a SH .12 in her and made about 4 passes in a mud path and on the fourth run, I shredded the rear input shaft in about 4 feet! I was thinking my custom made drive shaft would be the first to go, but it held up. BUT NOT THE GEARS! I saw on Redcat's website the replacement input shaft and it looks like metal. I will have to call and find out if it is or not. Before I even ran this truck, something told myself that there was a problem on the rear gearbox. But eager as I was to test run it, I said "it will hold"........... WRONG! I did notice there is a shim between the bearing and the input gear. I wonder if there was too much space in the gears. I still have the input shaft from the front gearbox so I can try to use two shims on it and see if that will hold. She was awesome though! And quick! I almost hit the camera on 1 or 2 runs!
Now that you mentioned it, I am interested in your run down tremors. PM me please!
