Product Description:
Hawks Motorsports is pleased to offer our clients the Gen III LS1 LS2 LS3 LS6 LS7 LQ9 Flywheel Bolt Kit, ARP Part Number 330-2802. This ARP Pro Series flywheel bolt kit is designed for Chevrolet Gen III/IV LS-series small-block applications using M11 x 1.5 flywheel bolts. The kit includes six 12-point flywheel bolts with a 0.880-inch under-head length. ARP specifies a 190,000-psi Pro Series rating for this application.
When you're putting an LS drivetrain together, the flywheel bolts are one of those small pieces you don't want to cheap out on. Six bolts are responsible for locking the flywheel to the crankshaft while the engine is making power and the transmission is putting that power to the ground. ARP's 330-2802 uses a larger-than-stock shank and flat 12-point head to give an LS builder a purpose-built fastener for a serious manual-transmission combination.
ARP manufactures these Pro Series flywheel bolts from aerospace alloy and heat-treats them before thread rolling and machining. The larger shank diameter is designed to improve flywheel register while the flat 12-point head provides the appropriate engagement for installation. The bolts have a black oxide finish.

VEHICLE FITMENT / FITS THE FOLLOWING MODELS
This is an engine/flywheel application, so fitment should be determined by the engine and flywheel configuration rather than vehicle year alone.
Verified LS Engine Applications
- LS1
- LS2
- LS3
- LS6
- LS7
- LQ9
- Gen III LS-series engines using the applicable M11 x 1.5 flywheel bolt
- Gen IV LS-series engines using the applicable M11 x 1.5 flywheel bolt
ARP's current manufacturer documentation identifies 330-2802 broadly for Gen III/IV LS Series small-block applications. Hawks Motorsports specifically markets this SKU for LS1, LS2, LS3, LS6, LS7 and LQ9 applications.
Important Vehicle Application Context
This bolt kit may be applicable to LS-powered:
- Camaro
- Firebird
- Corvette
- GTO
- CTS-V
- Other LS-powered vehicles
However, vehicle-specific fitment should be confirmed by the engine, crankshaft and flywheel bolt configuration. Do not assume fitment solely from the vehicle name or model year.
IMPORTANT APPLICATION NOTES AND EXCLUSIONS
- 330-2802 is for flywheel applications, not flexplate applications.
- The kit contains 6 bolts.
- The required thread is M11 x 1.5.
- The under-head length is 0.880".
- Verify that the crankshaft/flywheel combination uses the M11 x 1.5 LS flywheel bolt configuration.
- ARP's catalog lists a separate 234-2801 for Gen V 6.2L LT1/LT4 applications beginning in 2013. Do not substitute the LT-series application based solely on engine displacement.
- ARP also lists separate flywheel fasteners for other Chevrolet engine families.
- Do not use this flywheel bolt kit for a flexplate application. ARP lists 244-2901 separately for LS-series flexplate applications.
- ARP's installation instructions specifically state that washers are not to be used with these flywheel bolts.
INSTALLATION NOTES
ARP's current installation instructions for 330-2802 specify the following:
- Verify that the flywheel and application correspond to the 330-2802 part number.
- Confirm that there is adequate chamfer around the flywheel bolt holes to clear the radius beneath the bolt head.
- Do not use washers with these ARP flywheel bolts.
- Lubricate the bolt threads with Loctite 242.
- Apply ARP Ultra-Torque Fastener Assembly Lubricant to the underside of the bolt heads.
- Install the flywheel and initially tighten the bolts by hand.
- Tighten the bolts using an alternating or crisscross pattern.
- ARP specifies a final torque of 85 ft-lbs using the specified lubricants.
Always follow the latest ARP installation instructions for the exact fastener being installed.
