Gasket Kits
Gasket Kits: the seals that make a rebuild actually hold
A gasket kit bundles the seals your engine needs to close back up after it comes apart. Rather than sourcing head gaskets, valve cover seals, intake and exhaust gaskets one at a time, these gasket kits put the matched set for a specific engine in one box, so every mating surface between block, head and covers gets a fresh, correct-thickness seal. You fit one whenever you pull a head, do a top-end refresh, chase a coolant or oil weep, or build for more boost and need a gasket that clamps to the load you're running.
Get the seal right and the engine holds compression, keeps coolant and oil where they belong, and doesn't leak past a cover. Get it wrong and you're back in there. That's why the kit approach matters: consistent thickness and a full complement of pieces in one order.
What we stock
There are 370 gasket kits in this category, spanning 30 brands. Prices currently run from $17 to about $1,759 for what's in stock now, which is a snapshot and not a fixed quote. The deepest range comes from Cometic Gasket, the single biggest name here, followed by Victor Reinz, TwinPower and Athena, with Skunk2 Racing, S&S Cycle, Vertex Pistons, Brian Crower, HKS and Turbosmart filling out the rest.
Coverage is broad across cars, trucks and bikes. Of the parts with fitment data (250 of them), the top makes include Harley-Davidson, Ford, Dodge, Honda, Chrysler, Nissan, Yamaha, Chevrolet, Toyota and Subaru, with vehicles like the Dodge Ram 2500, Ford Mustang, Ford F-250 Super Duty, Nissan 240SX, Honda Civic and Harley-Davidson Dyna showing up often. The year range runs 1900 to 2024.
How to choose
First decide how far you're going in. A top-end kit like the Cometic Street Pro 6.7L Cummins top-end set covers the head and up, which suits a head job or head-gasket replacement. A complete kit like the Athena ZX-6R complete gasket kit pulls in far more seals for a full teardown.
Second, match the kit to your engine exactly. Head sets like the MAHLE Original F-250 Super Duty head set (14-11) and the 10-08 head set are year-specific for a reason. For built engines, note the bore and thickness called out in the listing, as with the Brian Crower VQ37HR gasket (98mm bore, 0.9mm thick) — the bore has to clear your pistons and the thickness affects your quench.
What else you need with it
If you only need the head-to-block seal, browse dedicated Head Gaskets. A top-end job usually pairs with fresh Pistons and Bearings, and while you're in there it's worth checking your Radiators and Oil Filters. Everything sits under the Engine Components section.
