I put the EPI Big wheel kit in Mine. With the Primary spring change it gives it more of a stall effect than when it kicks in Hang on. Yes it did make a big DIff when I was running Mud tires it let it rev a little higher before it engaged(about 500 rpm's i think they said)than pulled harder from the bottom and mid
