traxxas spurs

[Mike c.]

are there any stroger plastic spur gears then the traxxas one? or should I go with a metal spur.
also, is it possible that my tranny will be used to plastic spurs only and as soon as I put on a metal spur it will toast me tranny?

I don't know if there are any plastic ones that are stronger, but you should definately go with a metal spur. I think Taxxas makes one if your dad is still original parts only, but if I were you I would consider the slipper kit and spur gear from RRP. It is much better than the stock slipper and spur.

I use the RRP spur gear kit on my Maxx. The only thing is, there is a possibility of eating tranny gears if you still have the stock plastic or nylon, because that would be a weak link in the drivetrain. With the plastic spur gear you strip that instead of a tranny gear, because the weak link is the spur.

You might want to change your clutch bell also if you decide on a metal spur so they wearout evenly.

If you decide to stay with the plastic spur you might want to try a Kimbrough. Also, RRP makes a spur gear kit with a plastic gear.

I'd stcik with plastic unless your going to upgrade the tranny gears. Just like big kal said, the plastic spur if almost like a safety to your drive train, it strips so your tranny doesn't. And getting a new clutchbell with the new metal spur will help the gears mesh better/evenly and prevent binding.

RRP makes some great platic ones that can be found here:

You know I have heard so much about that and was leary to go to the new RRP double slipper with the steel spurr, but I just havent had any problems yet. Time will tell though as it hasnt been installed entirely to long.

I've been running steel spurs on my T-Maxx from almost day one. I have yet to upgrade or do anything to the tranny, and guess what...no problems. You are right about the weak link. I have chosen to use my center drive axles as my weak link (easy to replace and way cheaper than tranny parts). They are the old slider types, and I overtorque them pretty often.

The key to success in using any metal gear is proper gear mesh. It is even more important on the spur to clutch mesh. Screw that up, and you are going to be eating some serious dough to replace/repair the damaged parts.

I run RRP slipper disk set up with the steel ring gears. Light weight and very effective.

thanks, i think i'll go with RRP because it sounds like its better than stock, but won't strip the tranny

I run the metal spur as well. Kimbrough make a good quality plastic one if you can't afford a metal setup.

I feel I need to do a little

Metal or plastic doesn't matter as far as striping the transmission.
The key to trany health is the slipper adjustment. The slippers main purpose it to buffer the transmission from torque and shock. Adjusting it properly is important weather its stock or aftermarket. If you use a stock slipper setup make sure you have ALL the holes filled with friction pegs and make sure you replace them when they get worn.

Adjustment is easy. Start by GENTLY snugging the adjustment nut down then backing it off 1/8th of a turn. This will get you in the ball park. Start and warm it up. Hold your Maxx down tight to the ground with the front wheels against a wall. gently give it throttle. If the spur slips tighten it just a tad. Give it a short blast of 3/4 to full throttle. The slipper should slip from 1/8th to 1/4 turn no more no less. Tighten or loosen the adjustment ut as needed. If you have a hard time telling if it has slipped use paint and mark a spot. This will help see if its slipping.
I check my spur every time I start my Maxx. Its a good habit and everyone should do it.

I hope this helps.

I was told that you should do every other hole with a peg. why should I fill all of them?

 

[HumboldtBlazer]

more friction area is better. Those slipper plates ride up against those pegs and the either slip on them or grab, and its always better to have more surfave area in this situation in my understanding.

 

[SkyMaxx]

If you use a steel spur gear, you need to use all of the slipper pegs in all of the holes. The additional weight of the spur gear requires it for optimal performance. You can get away with using one every other hole on the plastic due to its weight.
