jeepstroker Posted March 30, 2016 Share Posted March 30, 2016 hi what is the best Flywheels for race use only ( stroker 5.1 ) Quote Link to comment Share on other sites More sharing options...
Administrators Moses Ludel Posted March 30, 2016 Administrators Share Posted March 30, 2016 jeepstroker...5.1L from a 4.0L/4.2L stroker? Wow, that's a lot of displacement. Modified 4.2L crank? What size bore? Which rods? Like you do, I sourced/searched at Summit Racing to see what's available. Centerforce pops up, I've used Centerforce clutches since the 'eighties. The steel flywheel is SFI approved and an internal balance type. If that's helpful, this may be one of the rare sources for a performance Jeep inline six flywheel: Brand:Centerforce Manufacturer's Part Number:400469 Part Type:Flywheels Product Line:Centerforce Steel Flywheels Summit Racing Part Number:CTF-400469 UPC:788442024654 Ring Gear Tooth Quantity:164-tooth Rear Main Seal Style:2-piece Flywheel Material:Steel Engine Balance:Internal Weight:27.500 lbs. Replaceable Friction Surface:No Safety Rating:SFI 1.1 Quantity:Sold individually. In-Store Pickup:Choose In-store pick-up (OH, GA, NV) on our web site. Centerforce steel flywheels are available for popular import and domestic vehicles, including trucks. They're CAD/CAM-designed and CNC-machined from billet steel for precise, no-hassle, bolt-in installations. No modifications are required in combination with either Centerforce clutches or other clutch assemblies built to OEM specs. These flywheels are SFI-approved, so you know that you can count on them--on the street and on the track. Advance Adapters and I have both supported Centerforce products for decades.

Administrators Moses Ludel Posted March 31, 2016 Administrators Share Posted March 31, 2016 jeepstroker...The OEM flywheel is fine for most uses. Resurfacing (step style when required) and balancing are always recommended. If you're building to this standard, I'm sure you have balanced all reciprocally moving parts in the lower engine, right?
