DNA Motoring GKTSET-XAXB Aluminum Replacement Gasket Kit
Our GKTSET-XAXB aluminum replacement gasket kit provides everything you need for a complete engine seal restoration. Each gasket is precision-cut from high-grade composite materials and features multi-layer steel construction for maximum durability under extreme heat and pressure.
We engineered this DNA Motoring gasket set to meet or exceed OEM specifications, ensuring proper fitment and long-term reliability. Whether you’re performing a full engine rebuild or replacing worn seals, this comprehensive kit includes head gaskets, valve cover gaskets, intake/exhaust manifold gaskets, and all essential sealing components.
Professional technicians and DIY mechanics trust our gasket kits for their precise tolerances and proven performance. The aluminum-composite construction resists warping and maintains consistent compression even after thousands of heat cycles.
GKTSET-XAXB specifications & construction
Multi-Layer Construction & Materials
The DNA Motoring GKTSET-XAXB aluminum replacement gasket kit utilizes advanced multi-layer steel technology for the head gasket, combining three to five layers of stainless steel with elastomer coatings. This construction allows micro-movement between engine block and cylinder head during thermal expansion while maintaining a perfect seal.
Our valve cover and oil pan gaskets feature nitrile rubber compounds that resist oil degradation and maintain flexibility across temperature extremes. The intake and exhaust manifold gaskets use fiber-composite materials reinforced with steel wire mesh, preventing blow-out under boost pressure or backpressure conditions.
Vehicle Compatibility & Fitment
Application Range
This gasket set is designed for specific engine platforms—verify your vehicle’s year, make, model, and engine code before ordering. The GKTSET-XAXB fits select four-cylinder and V6 aluminum-head engines commonly found in import and domestic vehicles manufactured between 2005-2018.
Our engineering team cross-references factory service manuals to ensure bore dimensions, bolt hole spacing, and coolant passage alignment match OEM specifications exactly. Each gasket features the correct thickness to maintain proper compression ratios and valve-to-piston clearances.
Installation Guidelines & Torque Specifications
Proper installation of the DNA Motoring GKTSET-XAXB requires clean, oil-free mating surfaces and adherence to factory torque sequences. Remove all old gasket material using a plastic scraper—never use metal tools that can gouge aluminum surfaces.
The head gasket installs dry without additional sealant in most applications. Position the gasket carefully, aligning all bolt holes and coolant passages before lowering the cylinder head into place. Follow the factory torque sequence in three progressive steps, typically 30 ft-lbs, 60 ft-lbs, then final torque plus 90-degree rotation (consult your service manual for exact values).

GKTSET-XAXB Gasket Kit Questions
The MLS head gasket installs dry without sealant in most applications—adding RTV can actually cause leaks by preventing proper gasket compression. The valve cover gasket requires a small bead of RTV silicone only at the cam cap junctions where the gasket meets hard corners.
Oil pan and timing cover gaskets are pre-coated where needed, but you may add a thin film of Hondabond or equivalent at split-line areas if your service manual specifies it. Always consult your vehicle’s factory service procedures for sealant requirements specific to your engine platform.
Check your vehicle’s engine code (found on the emissions label under the hood or in your owner’s manual) and compare it to the application chart included with the product listing. The GKTSET-XAXB is designed for specific engine families, not universal fitment.
If your engine has been modified with aftermarket cylinder heads or block, measure bore diameter and deck height to ensure compatibility. Contact our technical support team with your VIN and engine specifications if you need confirmation before ordering.
Yes, the multi-layer steel head gasket construction handles forced induction up to approximately 25 psi when proper head preparation and torque procedures are followed. The stainless steel layers and elastomer coating are designed to seal under elevated cylinder pressures.
For builds exceeding 400 horsepower or 20+ psi boost, we recommend upgrading to ARP head studs and having the cylinder head and block decks professionally surfaced to within 0.001-inch flatness. The gasket set itself remains fully compatible with performance builds when supporting components are upgraded accordingly.
Always follow your vehicle manufacturer’s torque specifications and tightening sequence—these vary significantly between engine platforms. Most modern aluminum-head engines require a three-step torque process: initial torque to 30 ft-lbs, second step to 60 ft-lbs, then a final 90-degree rotation (torque-to-yield method).
The application guide included with your DNA Motoring GKTSET-XAXB provides general torque ranges, but you must consult your factory service manual for exact values and sequence patterns. Using incorrect torque or sequence can cause head warping or gasket failure even with a quality gasket set.
No, valve stem seals and piston ring sets are not included because these are wear items that require measurement and individual specification based on valve guide and cylinder bore condition. Valve stem seals must be sized to your specific valve guides (standard or oversized), and piston rings must match bore diameter and desired ring gap.
The GKTSET-XAXB includes all gaskets and static seals: head gasket, valve cover, intake/exhaust manifold, oil pan, timing cover, and all associated O-rings and grommets. We offer valve stem seals and piston ring sets separately so you can select the correct sizes for your rebuild.
The MLS head gasket itself requires no curing time and the engine can be started immediately after assembly is complete and fluids are filled. However, if you applied RTV silicone at the valve cover or oil pan, allow 24 hours of cure time before starting the engine or filling with oil.
After initial startup, we recommend a break-in procedure of 20 minutes at idle followed by a cool-down period. Re-torque the cylinder head bolts after the first heat cycle if your service manual specifies this step (most modern torque-to-yield procedures do not require re-torquing).
Measure the cylinder head surface with a precision straightedge and feeler gauges before ordering gaskets. If warping exceeds 0.002 inches across any plane, the head must be resurfaced at a machine shop before installing new gaskets.
Even the highest-quality gaskets cannot compensate for severely warped mating surfaces—attempting to seal a warped head will result in coolant or compression leaks regardless of gasket quality. Most automotive machine shops can resurface aluminum heads for $100-200, which is a worthwhile investment to ensure your DNA Motoring gasket set seals properly.
