yea you need the screws like astross said they are longer than the ones that came out of it
 
the only problem i see running this damper past 3k rpm is the viscous fluid's centrifical force inside the unit get's alot higher, and it can cause the housing to crack, and then it leaks fluid, and well the damepr you just put on is no good. also don't forget you are going to lose you tach with this damper, you won't with a fluid damper, and they are rated to run high rpm, this one isn't. for the cost of everything you need to use this damper, it probably isn't that much more coin for a fluid damper. i can check at work tommorow and see what it costs for eveything you need to make this damper work.

haisley runs them on a few of there trucks. If I remember correctly I think I paid under 300 for one for a puller I built. No problems at 6 grand. To get the tach to work I built a simple mount that moved the sender to read the mounting bolts.Also with the thicker billet front covers you have to machine 2 ribs off it and then use a thinner belt
