MSV Racing OptiFlo Impeller—The Ultimate LT500 “Quadzilla” Cooling Solution!
When we saw the poor OEM impeller on the LT500 Quadzilla, we knew riders deserved a high-performance upgrade that only MSV Racing could provide. MSV Racing developed the OptiFlo Impeller—designed to cool the big bore ATV far better than anything else on the market.
What Sets OptiFlo Apart?
🚀 Precision Engineered for Maximum Cooling
- Optimized Blade Design – The perfect number of blades minimizes fluid slip, improving overall efficiency.
- Superior Flow Control – Blade shape and angle smooth coolant entry and exit, reducing flow separation and turbulence for a more stable and effective cooling cycle.
- Ultra-Strong Billet 7075 Aluminum – Crafted from high-grade aluminum, ensuring extreme durability and long-lasting performance.
- Smooth Surface Finish – Reduces fluid friction and turbulence, preventing heat buildup.
- Advanced Sealing Technology – A conical sealing washer and pan head fastener smooth coolant entry, reducing aeration and improving reliability.
Why Increased Coolant Flow Matters
An increase in coolant flow rate = better cooling performance. The rate of heat transfer from the engine to the cooling system is directly proportional to the mass flow rate of coolant. It works on the principle of source (engine) to sink (radiator) differential—and the more efficient the transfer, the better your engine stays cool.
Tested & Proven Performance
Todd Witz, owner of Witz Motorsports and a Quadzilla specialist, ran his dune quad 300-400 miles, burning through 40 gallons of fuel, and reported up to 20°F cooler running temperatures. In low air-flow situations, where Quadzillas often struggle, the OptiFlo kept his build running strong!
Maximize Performance & Keep Your Engine Cool
🔥 Horsepower & RPM = Heat—but preventing heat soak is the key to maintaining top performance. The more efficient your engine’s cooling system, the more power it can handle. Upgrade your LT500 Quadzilla today with MSV Racing’s OptiFlo Impeller—cool smarter, ride harder!

Haven’t installed yet but very high quality.
I would like to see you make one for the LT250R.

Fit perfectly 👌

First impression? Sure made bleeding the cooling system quicker! Maybe it has less cavitation or just the extra flow, but it made bleeding the zilla that has an auxiliary radiator much easier.

Been looking to upgrade my zilla impeller and saw the machined oem style on facebook which I almost bought. Then I found this one which is obviously a cooling upgrade! I see cooler temps everywhere.
