These things are awesome! I have had no problems with my steering blocks at all. Also if you want to prevent the bones from popping out use the rear outdrives in the front. I did this and it solves this issue. Have been running these all the way up to 4s. About to test them out on 6s and maybe 8s in the future.
I LOVE these shafts! Much better than MIP's - I haven't had anything break running the Viper 5150Kv 4-pole system on 2S, landing 10-foot jumps with the throttle buried. BUY THESE. Need I say more? Well, yes. The one negative is that your wheels and hexes are now your drivetrain's weakest point. MAKE SURE your wheel nuts are securely tightened or both your wheel and hex will end up quite round. Some closing advice: BUY THESE.
Installed the rear set right away but thought I could get decent life out of the stock fronts but I replaced a couple fronts which was no big deal at 10 bucks until I recently broke the fronts in baja with no spares available so I had these waiting for me when I got home. I trust they will be as worry free about breaking as the rears but I did run into one issue.
I immediately noticed my steering wouldn't center very well at all so I removed the servo horn to turn the wheels by hand and there was major binding. I loosened the shoulder screws going into the knuckle through the hub a few turns and it was still pretty tight so I cinched them back down then loosened all 4 about a half turn and just manually turned left to right and back bout 100 times and it feels much better now but still a bit tight, but the steering does center. I will let it wear in a bit driving it around then re-tighten the shoulder screws as much as I can before it starts to bind. Really not a big deal just wanted to make note of it.
These driveshafts are amazing. They build easily and are a perfect fit. My slash now accelerates better and the new shafts handle strain much better. Great Product and Great Customer Service from Amain!
awesome product no way the pin can fall out nor can the drive shaft pop out make shure you buy the metal hub adapters
The front shafts have worked well for me. If you are running very long travel the "bones" may come out. In this case I suggest looking at the outdrives for the pro-track suspension TKR6828X (longer). Have had no part breakage but maybe my lines are cleaner than other reviewer's were? Tekno has come out with some new stuff you may want to review their web site then come back here and order...
Way better than the stock plastic ones, have had no issues so far even in the colder weather.
I have had these drive shafts on the rear of my stampede 4x4 for 2 years now and they are holding up perfectly. Just bought these from my local hobby store who ordered them off Amain for me and on the first battery pack the driveshaft broke. I was very surprised because i don't bash hard and Tekno has always made strong products. I still would recommend these over the MIP shafts due to how light and easy on the diffs these shafts are but still a bit let down that they failed on the first pack of a light bash.
Axles are perfect just have to have some grease where metal meets metal otherwise it makes a bad sheering noise. Stock screws that go into the steering blocks are too short. I ended up getting 20mm ones but would go with 18mm
Everything fits perfectly just like the rear pairs bought first but this time the threaded pins for the differential outdrives could just barely not fit in the threaded hole on the drive shaft cup. Think it was just an accident with the machining blade maybe it wasa bit worn or something when they machined this one but will replace the cups and the pins should fit perfectly
I have ran these for a few days now, for at least 4 hours in total. They have been been overall a good driveshaft and have held up to backflips and 4s abuse. I have had to lower the suspension because the shaft would pop out of the cup when the suspension drooped in the air. I have been running it with the arms about level and that has fixed the problem. I didnt even try the 12mm plastic boxes that come with the kit. I drilled out my mip 17mm hex adapters to make them fit.
Weak ball ends. Broke one of them off on the 2nd pack. No warranty. Would not recommend.
Running these on a slash vxl 4x4. Stock axles won’t last one 2s battery and been hammering on these with 3s for a few days now without any problems. Very light weight and no vibrations either! Excellent for the price! Thanks Amain!
Fast delivery to Russia! 13 days! The set of drives is excellent! However, it is not clear why the manufacturer does not put in the set of internal bearings?
Amazing Driveshafts for the money. They are easier to assemble than the MIP shafts and have held up just as well on a 2650kv motor and 3s. Would reccomend as an affordable upgrade for traxxas 4x4 trucks
Rear went on without any problems. These came without the right amount of the .8mm washers (4 instead of 6) so the toe will be all out now. Stub axle was also not machined perfectly so it caught on the inner bearing making it a nightmare to install. Lack of shims was an issue aswell lucky I ordered extras to shim the rears as they also did not include enough. Love the product but quality control was not there unfortunately.
These are nice light and conveniently designed. However I managed to snapped a pin barrel in half somehow during the first run on 3s. Not sure what happened, I didn't crash into anything, but I'm working on getting a replacement, it's entirely possible it was a freak accident with the one part.
Love the shafts, HATE the steering blocks. They are the weak point of my Slash. They break all the time and sometimes take out the caster block with them. Also the shafts are too short. You have to shim them all the way in and then run massive negative camber to keep them in. Don't waste your money!! Can't even compete because my truck is too brittle!!. Thanks for nothing Techno!! Ruined my race season
