Hello,

I've purchase a MOTOBLUE 25% Under-drive Crank (harmonic balancer) Pulley. I now am reading that underdrive pulleys do no have a dampner and could cause premature wear of the crank bearings...... being a newby and not knowing about this wonderful forum before I purchased the pulley, I am not sure if the balancer includes a dampner or how the whole thing works...... Little Help!!!

Thanks!!

send it back. People are having problems with their car after they install these.

 

ive never been a big fan of the underdrive there too much hastle and problems for just 2.5 to 5 hp

 

Thanks for the responses!!

I think I'll leave it alone, the meager extra HP is not worth the uncertanty.......

Thanks again this forum is awsome!!!!!

 

What he said!!! That one has 0 gain on our cars. Send it back!!!
