Spur
Great fit, machining was clean no sharp edges, works great and has held up so far

Great spur! Much quieter compared to steel
This one runs alot quieter than the other one in my 2nd trx4 that is steel,this one is also much lighter and puts less strain on the drive train and way more initial start out punch from a dead stop
