What is the best replacement LS1 flywheel? I have a 99 TA with 263000 miles. We are swapping in a rebuilt LS1 with TV2 cam and ported heads. The A4 tranny was rebuilt and 3000 stall was added. We are planning to a 373 gear swap. The flywheel looks OK. But, while everything is apart, I think this is a good time to consider an aftermarket flywheel. The car will be used mostly on the street with occasional trips to the track. Thank you in advance!

Not to confuse people, but its actually a 'flexplate'. Most people assume when you say flywheel you are talking about a manual trans.

The stock flexplate is actually very stout, unless its bent / beat up id run with the stock one. You can get used stockers for 40-50 if you do think yours is bad.

Stock is fine, your not setting the world on fire and your not that fast that you need a SFI rated flex plate. IF the cost is reasonable always go for the better/safer plate but stock I would not even think twice to look at.

The Hughes looks pretty nice especially at around $150.

Flexplate failure is an issue on later (01-02) cars in HP applications, IIRC. TCI units have a good rep, but grind off the powder coating around the bolt holes.

Spend the money on a bigger stall. A Tv2 needs more than 3000rpm, 3600-4000 would be much better.

'98-'00 flexplate is pretty strong. Since the OP has a '99, I wouldn't worry about this for a simple heads/cam car. I would be more concerned if it was an '01+ unit though.



Agreed. 3000 isn't even enough for the stock cam IMO. I would consider 3500-3600 the minimum.

Agreed with above. Failures are more prone to the later years and their redesigned unit. Basically, its thinner and more prone to crack. Always a good idea to replace any stocker though.
