"I was skeptical about using epoxy, but after 2 years of daily driving and track abuse, my block is still perfect. No cracks, no overheating. Best $229 I ever spent on my build."

The Smart Alternative to Closed Deck
EPOXY54 is a custom-engineered, high-temperature epoxy specifically designed to reinforce engine blocks. It provides the strength of a closed deck system while maintaining OEM cooling efficiency—all at a fraction of the cost.
Traditional closed deck solutions require extensive machining, high costs, and often warp cylinders during install. EPOXY54 gives you the strength you need without the compromises.
Trusted by the fastest engines in the ¼ mile, EPOXY54 has proven itself in race and street applications.
21,000 PSI Strength
Compressive strength that rivals closed deck solutions at a fraction of the cost.
Thermal Matched
Engineered thermal expansion rate matches aluminum perfectly—no cracking or separation.
DIY Friendly
No machining required. Install before or after machine work without affecting dimensions.
Cost Effective
Achieve closed deck performance for significantly less than traditional alternatives.
Debunking the Myths
Let's address the common misconceptions about epoxy block reinforcement with facts.
Myth: Epoxy will overheat your engine
Truth
EPOXY54 maintains stock cooling efficiency. The coolant passages you drill preserve full OEM cooling properties.
Myth: Epoxy is weak and will crack
Truth
21,000 PSI compressive strength with thermal expansion matched to aluminum prevents cracking under extreme conditions.
Myth: Coolant will deteriorate epoxy
Truth
Chemical-resistant formula specifically designed to withstand coolant exposure indefinitely.
Myth: The epoxy will melt from engine heat
Truth
EPOXY54 is a high-heat epoxy that withstands normal engine temperatures. Users have reported warped cylinder heads from water pump failures without any epoxy damage. In short, if your engine is getting hot enough to damage the epoxy, you have bigger problems on your hands.

"The installation was way easier than I thought. Followed the video, waited 24 hours, drilled my passages, and was running within a week. Temps stay perfect even on the track."
Sarah Rodriguez
"Coming from a closed deck setup that cost me $3k in machine work, I wish I had known about EPOXY54 earlier. The performance is identical, but my wallet is much happier."
James Thompson
"The fastest Volvo blocks are all running EPOXY54. After seeing the dyno numbers and durability, I had to try it. Three seasons of racing later, zero issues. This stuff is legit."
David Park
"When you're pushing 1200+ HP through a block, you need every advantage. EPOXY54 has held up to punishment that would destroy most setups. Absolute game changer."
Chris Martinez
"I run a performance shop and we've installed EPOXY54 in over 30 builds now. Not a single failure. Our clients love the cost savings and the peace of mind."

Simple Installation Process
No machining required. No special tools needed. Just follow our proven 5-step process and you'll have a reinforced block in 24 hours.
01
Prepare the Block
Fill the water jacket with a temporary solute like sugar or salt. This creates the void space for coolant passages.
02
Mix & Pour Epoxy
Mix EPOXY54 and pour it to fill the top ¾" of the block. The runny consistency ensures a clean, seamless application.
03
Cure for 24 Hours
Allow the epoxy to cure completely. Unlike other closed deck solutions, EPOXY54 is ready in just 24 hours without the need for machining.
04
Drill Coolant Passages
Following your head gasket design, drill the necessary coolant passages through the cured epoxy.
05
Dissolve & Flush
Dissolve the temporary solute with water and flush it out, leaving behind a perfectly reinforced block with optimal cooling.
