I bought a gmpp clutch upgrade kit for 08 ss BALT & a zzp light weight flywheel to match. Does anyone know if i will need to purchase a throw out bearing spacer for this set up. I asked zzp & they say you'll have to measure. I kinda need to know before hand to have the part on hand. I guess i could always buy it just in case & return it if i don't need it. Just curious if anyone knows. Thanks

 

I'm upgrading my clutch. At 185xxx it's starting to slip. Did you end up needing the spacer after all?

 

Nope! Didn't end up needing the spacer. I measured it anyways like Al shows you on the zzp website. Gmpp clutch/lnf t.o.b./zzp lightweight flywheel/ new AC-Delco master cylinder/ steel braided clutch line. I'm full bolt on T-Man tuned for canyon carving for 91 oct. Im @ 208,XXX miles no problems
