Forced Induction - Thunderracing and keyed hubs

I heard years ago thunderracing use to give a core charge towards sending your stock crank hub to them and them sending you a keyed hub. but i see nothing on there site. i have seen acouple complaints on there machine work also. just curious

Might try email or call them ;)

emailed them a week ago no response. i might have one anyhow now.

I have one and it is fine.
