Kraton Fairly new to hobby , this 12s Kraton EXB is mainly field and flat track Blaster not Basher. Was having some thoughts on 45/47 gearing.

I'd go 39/39. Is the exb bone stock with the max4?

Why not just put a 37t pinion on? Would be almost the same ratio as 45/47.

From the videos I've seen, the max 4/800kv combo is a screamer. Dbxle's with what you have wheelie at 50+ mph, and they are heavier than K8s so its going to be even more of an issue with the K8. You might have a problem keeping the front end down at speed unless you put a drag wheelie bar on. You also might not be able to full trigger pull til its going 60+ unless you have a football field size area to try it. I would pay attention to the diffs and outdrives. I would recommend using earplugs for the center diff also.

Yeah really no point to change the gears to that, what are you trying to achieve by doing 45/47? That thing must be a beast though lol I cant imagine. Gatta think that motor gets pretty darn hot pretty quick also?
Side note, I have never seen a on/off switch on a battery. Makes me think you charge the batteries while they are in the truck?

Niiice .. I’m running 20 mil 500,000 rear 1 mil in front. I was thinking bigger gears with the power to push them would ultimately be faster? We do run football size fields usually a couple laps. Trying to keep up with a guy running big 50 something 1.5 gears

Not going to be faster though because you are increasing spur which slows you down but also increasing pinion which speeds you up. If you want faster then you need to just go higher pinion

When I was running my xlx2 800 combo I had it overdriven for a bit and had no issues. 41/39.
With the 47t spur you are limited to the size of the pinion if you are using the stock motor mount. To go 1:1 with the 47 you need an aftermarket motor mount. One reason most people will just go with the 39t spur to have room on the slide to fit a pinion to get 1:1

Yeah I saw an aftermarket will take 45/47. Hey Guys I really appreciate all thoughts and input on the subject. Realistically I need to learn to drive better, have crashed Thrasher twice pretty good . I can run 34/39 all day and won’t even get hot.

Have fun man. That's what we do it for! Yea breakage is inevitable, but imo, wrenching and fixing is just as fun/satisfying.
