Very good quality

By   on  Verified Purchaser

Every gasket needed for top end was in the kit, very good quality.


The kit came with all the gaskets

By   on  Verified Purchaser

The kit came with all the gaskets you need to do a quality top end rebuild plus torque instructions for the heads, the only thing you could whine about is it would have been nice to have had a gear chest gasket, but I guess that's not top end.


Thank you

I’m happy with the item.


My 97XL1200C Sportster rebuild

By   on  Verified Purchaser

Great price and great gasket set, which I’ve used before!


Very satisfied

By   on  Verified Purchaser

Very extensive kit. The cometic gaskets are top shelf high quality parts and the kit has precisely what you need to do a complete top end rebuild. Very satisfied.


Cometic Top End

By   on  Verified Purchaser

Bought Cometic gaskets to replace factory Harley Davidson cylinder base gasket. Good quality you would expect from Cometic and all gaskets needed for a top end rebuild were included. Fast shipping and good service and excellent price from Parts Giant.

Questions & Answers

Ask Question

Does it come with a list for what all the rubber o rings are for

Every Cometic gasket kit comes with a placard that indicates what's to be included within the box. Sometimes, OEM numbers are also included on that card. And with that information, you should be able to determine what gaskets are appropriate for servicing your machine.
