Why Choose Custom Epoxy for Aluminum Engine Blocks?
 
Key Benefits of Our Custom Epoxy Formula:
Permanent Bonding:
Specifically designed to adhere permanently to aluminum.
Reduces vibration, minimizing cracking risks and eliminating false knock issues.
Thermal Compatibility:
Engineered with a thermal expansion rate closely matching aluminum for long-term stability.
Unlike cement alternatives that expand and shrink during curing, our epoxy is non-expanding and non-shrinking.
Prevents piston clearance issues and preserves cylinder integrity.
Easy Installation:
Runny consistency ensures a clean, seamless application.
Can be applied before or after machine work without affecting dimensional accuracy.
Why Epoxy?
Pros:
Cost-effective: Significantly cheaper than alternatives.
DIY-friendly: No machining required (deck surfacing remains untouched).
High strength: 21,000 psi compressive strength.
Specially formulated: Optimized for aluminum blocks.
Quick drying: Cures in just 24 hours.
Retains cooling system: Stock cooling properties are preserved.
Durable: Chemical-resistant to coolant, ensuring longevity.
Daily driveable: Suitable for both street and track use.
Cons:
Aesthetic simplicity: May not look as polished as aluminum.
How Does It Compare to Alternatives?
Unlike cement or other fillers, epoxy does not deteriorate or erode over time.
With chemical resistance to coolant, it ensures reliability for the long haul.
Proven Performance Across Platforms
The fastest aluminum-block engines in the ¼ mile rely on epoxy to reinforce their blocks, proving its capability under extreme power and stress.
Trusted and tested across various platforms, including VQ, Volvo, BMW, Subaru, and Top Fuel Drag Bikes.
Customer-Proven Results: Real-world applications demonstrate unmatched durability in high-performance environments.

Daily Drivability & Performance
Designed to maintain stock cooling efficiency, comparable to CSS blocks or closed deck platforms.
Ideal for high-performance and everyday use, with no compromise on cooling or engine longevity.
Installation Made Simple
Fill the block with a temporary solute (e.g., sugar or salt).
Pour the high-temperature, 2-part epoxy to fill ¾'' of the block.
Allow it to dry for 24 hours.
Drill coolant passages according to the head gasket design.
Dissolve the solute with water, leaving behind a durable, custom-fit epoxy layer.
