Moved some things around in storage and realized I still have this. Bump!

This made the truck noticeably smoother during operation, quicker throttle response.
Combo of this damper, Dieselsite crank pulley and vacuum pump delete dropped my 0-60 by half a second.
Install is simple with a puller & install tool. Only thing that has to come off the truck is the belt, there is nothing in the way for install.

For anyone who hasn’t done an install & bought the tool already- Leroy rents one low cost and 65turbogarage sells one low cost.
The autoparts store kits that get rented out don’t usually have the right size threaded rod.
NEVER use a hammer (ruins the balancer). NEVER use the factory crank bolt (ruins crankshaft).

All the years and engines that these balancers have been put on, not gonna find 2 people say they didn’t like the results. 1 might say it just to stand out- haha.
