I run one of these in my 8T 2.0, plus I have adapted 2 others in a muggy and Xray and I am yet to strip a single spur. As said before it all about mesh and also quality of pinion. The Muggy has a 1717 in it and the 8T has a 1520 so the spur can handle some serious power, just get the mesh right. The old fashioned Paper trick works well and always remember after it’s all tightened down you should be able to feel just a hair of play between the pinion and spur too much play and it will strip; no play and you will grind the teeth on the spur also causing it to eventually strip.
These work great in buggies and last a long time if meshed correctly. I have run them in my 8ight and RC8 (Losi center diff) with no trouble. Saves wear and tear on pinions and run nice and quiet. Do NOT work with old school Tekno motor mounts or any mount where the motor is not mounted directly to the center diff bulkhead.
Works well for me, Running a Castle 2200KV in a E 3.0 on 4S, Shows signs of wear and tear from being exposed, but still works fine. As long as the mesh is good, this gear should last awhile.
Two of us ran the new Losi 3.0 truggies today with plastic gears and they were both stripped within a couple of races...I ran the metal gear in a 2.0 8E truggy all last year and never had a problem. I'm going back to the metal one!
These are absolutely fine if you can set the mesh properly and know how to drive like you are running a plastic spur.
Reviewers largely agree that this 45T plastic spur works well in 8ight-E 2.0 buggies when the mesh is set correctly, with several reporting long service and little wear, including in higher-power setups. Mesh adjustment is repeatedly cited as the key factor, with reviewers describing a slight amount of play as ideal. Opinions diverge sharply on durability in other setups. Multiple reviewers report stripping in truggy or brushless conversions, especially with higher-KV motors, and some recommend switching to the metal spur. One reviewer notes the gear is not suited to older Tekno motor mounts where the motor is not mounted to the center diff bulkhead. Reviewers also report wear from exposure, though some say it still works.
