Is anyone familiar with the differences between the flywheels from LSJ to LNF? The LSJ flywheel is just over $100, while the LNF flywheel is a little over $550. That's a pretty big difference, so I'm assuming some improvement was made.

Any info would be appreciated!

 

Anyone?

 

werd, the LNF flywheel and clutch i do believe to be larger than the LSJ one which would be one reason it costs more tho your numbers seem WAY off. Links?

 

i believe the clutch/flywheel combo that GM sells as an upgrade for the LSJ is just the SS/TC compnents. It probably has something to do with being much stronger to handle the no-lift-shift abilities.

you should buy one of each and build a contraption to do load tests for clutches.

 

I was just going off GM Parts Direct pricing.
That could probably be incorporated into an engine dyno, but I'm betting it would be extremely expensive!

 

lnf clutch feels much stronger than my old lsj

 

The LNF flywheel is a dual mass variety designed to take low frequency oscillations out of the drivetrain. Just like my LT1 vette. Weight 55lbs like my LT1 vette too.

 

Another + for the TC

 

I'd rather have a light flywheel than that heavy ass one.

Overall the LNF has a much bigger clutch than the LSJ.

 

55 pounds is alot for a daul mass flywheel in FWD my svt focus was only 33 lbs and if thats the case changin the flywheel would make a huge difference in performance.
