Evo 123 - ARP - 7-Bolt 4G63 Flywheel Bolt Kit

ARP 7-Bolt Flywheel Bolt Kit for the 4G63

A set of seven ARP flywheel bolts that fasten the flywheel to the crankshaft flange with greater and more consistent clamping force than stock. Stronger flywheel bolts are essential once you raise power and add a higher clamp load clutch.

Why it matters on your Evo 1-3

The 7-bolt 4G63 puts the full torque of the turbo engine through these fasteners. Factory flywheel bolts can loosen or fail under hard launches and aggressive clutch engagement, which risks a spun flywheel and catastrophic damage. ARP bolts provide the clamp load needed to keep the flywheel locked to the crank, making them a must-have for any clutch or built engine upgrade.
