Cobalt ARP Flywheel Bolts
ARP flywheel bolts for the Ecotec LSJ
I ordered these ARP bolts for the GMPP clutch, with the stock flywheel for my 06 Cobalt SS SC 2.0L ecotec LSJ.
ARP Flywheel Bolt Kit Vauxhall/Opel P/N 209-2801
Available here.
I haven't received them yet, but they look like they will fit better than the ARP 203-2802.
They are the correct thread (M10 x 1,25 and the correct length) and Opel GM made the ecotec engines,
but none of the ARP bolts specifically say they will fit a Cobalt LSJ.
Update: The bolts came iin. The ARP bolts are 2mm thicker heads the GM bolts. (6.5mm vs 4.5mm thcik).
The ARP bolts will fit without rubbling on my new GMPP clutch, but because my flywheel is thinner than stock (I resurfaced it), it eventually will wear, and contact the ARP bolts. A new flywheel wouldn't have this issue, and it will only rub by 0.3mm at the end of the clutch's life. So it will work for me, and I am going to put it together, and send it! I guess I could grind the ARP logo off the heads, but I don't really care about the 0.3mm potential contact.
