Hi Guys,

I have a hub here that is the stage 2 type, and a pulley, but I cannot seem to find any information on them on the internet. The hub has TR1996HS on it and the pulley has TR2000 on it. Has anyone seen these numbers before? It is a 4 bolt hub and pulley system.

Thanks. Gene.

 

Anyone know?

 

I wanna say that's ZZP or Intense? I know i've seen that marking before

Wait, 4-bolt...

I had a SFPHQ pulley-hub that was 4 bolt, maybe that's where I saw those markings.

 

The GM stage pulleys are a 4 bolt pattern. If you are curious on the size, just measure the pulley via tape measure. If you are thinking its a stage 2 then most likely a 2.8-2.9

 

its a sfphq, i just check mine.

it is probably a 3.0 because my 2.8 has tr2002 and my 2.9 has tr2001

 

GMS2 tends to use blue bolts in a 4 bolt pattern. The Stage 2 pulley has 77.9mm stamped on it.

 

Sweet, I forgot what my old pulley looked like

SFPHQ FTW.

 

Thank you very much guys. It is a SFPHQ 3.0! TR 2000!
