If your Honda TRX400EX is blowing smoke or losing compression, this Caltric cylinder head and gasket set might be exactly what you need.

These aren't some sketchy off-brand parts - they're precision manufactured to match OEM specifications for the 1999-2004 Sportrax 400 models.
The set includes both the head gasket and base gasket, which is super convenient because you typically need to replace both during a top-end rebuild.

The quality is actually impressive for the price - clean machining and proper material thickness that should seal up nicely.
Installation is straightforward if you're comfortable with engine work (if not, maybe leave this to a mechanic).

We strongly recommend comparing the photos to your existing parts before ordering to ensure perfect fitment.
Way cheaper than buying from the dealership, and honestly performs just as well in most cases.
Perfect for when you're doing valve work, dealing with overheating issues, or just giving your ATV some well-deserved TLC.

The packaging is simple but protective, and the gaskets arrive ready to install.

Whether you're a weekend warrior maintaining your trail machine or a mechanic stocking up on common repair parts, this set delivers solid value.

Your four-wheeler will be back to tearing up the trails in no time with proper compression and no more oil leaks!
