*Please see our other store listings or contact us for other kits – all at great prices!

This gasket kit includes all the gaskets, seals and O-rings shown in the photo.

The primary cover gasket is 0.045″ (1.1mm) thickness fibre material that is fully silicone beaded on one side as shown in the photo. It will come to you perfectly flat. We never fold, roll or otherwise allow any gasket to get damaged in shipping.

If you prefer a foamet primary gasket – we also have kits with the foamet gasket at very good prices!
The big difference between the gaskets is that the foamet gasket (rubber on both sides of a steel core) is stiffer and re-usable, whereas the fibre gaskets usually don’t work very well if you try to re-use them. Please see another one of our listings or ask us about a kit with the foamet gasket.

**AIM Clutch**  If you have an AIM clutch… you are going to need a little more room for the clutch under the clutch/derby cover, so you will want the derby cover gasket with the center cut out instead of this solid cover gasket. We have another kit listed with a picture of the foamet gasket that will work for you. Or you can just tell us or make a note that you want the gasket with the hole in the middle. Easy enough to change, and the price is the same.

Note that this kit has a 5-hole derby cover. If your derby cover has only 3 screw holes, we have another kit for you with a 3-hole derby gasket. Same primary gasket, and about the same price for the kit.

The 5-hole derby / clutch cover gasket is foamet – rubber on both sides of a steel core. It will not leak and no sealant is necessary.

The inspection cover gasket is foamet – rubber on both sides of a steel core. It will not leak and no sealant is necessary.

The oil seals included are exactly the two you will need – you won’t be short!

The two spacer washers (“tower washers”) are also foamet with an adhesive back that will keep them in place as you install the cover. The washers are turned upside down in the photo, showing the peel-off strip covering adhesive on the back.

Our products are brand new and made to high standards to meet or exceed OEM specifications.
