    Yes but be careful there are a lot of people that shouldn’t mess with #### that can burn it up. Do your research and don’t just go with the cheapest first guy you find. Cause end of time you’ll be lucky to feel the difference in the seat. If you’re looking to pick up a gear or even half a gear on a certain pull I wouldn’t count on it.


    If it was mine I’d give it a good manual health check and tune up and call it a day

    Sounds good to me, we don't haul heavy but we move a lot of wind going down the road and plenty of short steep hills, single lane, short runs on multi lane. 4:11 rears and RTLO 13 should help in the climbs.

    Thanks for your help.
