The RAM I posted has organic on one side and ceramic "puc" type material (not sure what it is made of)
The ZOOM HP is Kevlar on both sides.
Organic/ceramic disc clutch will not hold as well as a "puc/puc" type disc.
Beyond the disc material itself the construction and materials used in the disc, IMHO, is also a factor in my choice of clutches. My nod went to the ZOOM in that area.
I have seen the RAM fail when the disc did shear from its hub. The ZOOM MC series of clutches is a "stock" replacement but when I spoke with the ZOOM tech he said they no longer offer the MC series for the LT1 (MU disc type)

I did compare the RAM HD. I wanted the kevlar material vs the RAM iron/organic composition material of their HD.
Not a fan of encased disc springs and the RAM HD disc has "fingers" that attach disc hub to outer ring vs solid metal disc of ZOOM.
Just my $02

The clutch in your picture is not the powergrip HD. It is just the ram powergrip which is their dual friction clutch (900/300 friction materials) while the powergrip HD has the same friction material (900/900) on both sides. So either you ordered the powergrip or they sent you the wrong clutch.

its a good clutch my car is making 428RWHP N/a, 590RWHP on spray and it holds as long as you let it cool down good between runs. As far as driving on the street its ok I guess but with the surg of the cam it can become a pain real quick

i know the RAM in my pic is not the HD...again I chose the ZOOM for its disc construction and material (Kevlar)
Not knocking the RAM, just did not pick that one standard or HD
