Dayco XTX FTW... I've put mine through the ringer... (I have the HL 3GX, which is just the Dayco XTX with HL's logo on it... has the Dayco part number on the sleeve)... I've pulled a Polaris Ranger that had both front axles broken, all around out where we ride, through some nasty holes... and that Ranger weighs a lot more than the Brute... I didn't slip the belt at all pulling him around.. This belt is NOT the same as the HL Pro Series, or any other aftermarket belt... this one works!
Either go with the XTX or OEM... if you become a Subscribing Member on MIMB, you can pick up the XTX from Mud-Throwers.com for about $90...
