drive coupler life
 

What kind of life expectancy can be expected behind a 650 hp supercharged 502? I just lost another coupler. This one lasted about 90 hrs. Both the orginal and this one shredded the rubber and the splines were fine.

Any recomendations for a supplier. The last one I bought from Total Dollar If I remember correctly.

if it is the rubber part of the coupler that is failing, it is more than likely an alignment issue, 650hp on a good quality coupler should last much longer than that.
