Does anyone know of they make one for the trucks? I am looking for a 10% od one for my new motor and cannot seem to find one.

 

This is the closest I've found

ATI Super Damper Supercharged Series Harmonic Balancers 918625 - Free Shipping on Orders Over $99 at Summit Racing

Pretty sure the ls3 has the same pulley spacing.

But that's a 10Rib not a 8 Rib, its odd they claim its a 6% OD but yet according to them stock is 7.48 and that pulley is 8.19 so that's 9%........

 

That have it. Just give them a call.

 

For a 10% (8.19") 8-rib try shell# 917108 with hub# 916430M. I would call ATI to verify before ordering though.

 

I found that also but it seems that's designed with the ls7 in mind. Ya I'll call eventually, my buddy deals with them

 

In some older literature I have (2011), they show using the same shells on the LS3 Camaro and truck 10 rib conversion kits as currently listed under the LS7 balancers on the website. Therefore I presumed the only difference for the LS7 crank with Camaro/Truck accessory spacing was the hub itself.

For an additional sanity check, ATI lists the same shell (917073) for stock diameter 6-rib on Z-body, LS7 and truck applications.
