Product Details

The Frostbite FB308 is a high-performance 3-row aluminum radiator engineered specifically for GM LS engine swap applications. Built to handle 600+ horsepower, this radiator combines superior cooling capacity with show-quality aesthetics, making it ideal for muscle car restorations, hot rods, and custom builds requiring maximum thermal management.

Key Features:

  • 3-row core construction supports applications exceeding 600 horsepower
  • Dual-pass cross-flow design maximizes cooling efficiency by forcing coolant through the core twice
  • High-density core with more cooling fins per inch for superior heat dissipation
  • 100% TIG welded (brazed) seams for leak-proof reliability
  • Polished aluminum tanks and top plate for premium show-car appearance
  • Billet aluminum filler neck with included Frostbite 16 lb. high-performance radiator cap
  • Factory-style brass petcock drain valve for easy maintenance
  • Backed by manufacturer's 1-year limited warranty

Designed for LS engine swaps into classic GM platforms, this radiator delivers the cooling performance demanded by modern high-output engines while maintaining a clean, professional appearance under the hood. The lightweight aluminum construction reduces weight compared to copper/brass radiators while providing superior heat transfer characteristics.

Ordering was very quick. Its still a little strange not knowing the company or the people you're buying from, but the pricing you offered was very reasonable and the option for 2nd day air shipping was very satisfying. I had actually placed an order with Walmart after speaking with both autozone and advanced auto parts. Although my order was already being processed by Walmart, I canceled it in order to try your service as you could get the product to me faster than walmart could; so I'm praying that all goes well with your company. Thanks. C

simple, easy. I like how it matched the product with my car and said it would fit make and model...I hope it fits!

14.00 Little high for UPS shipping... But cheaper than Oriely's

Very quick and easy transaction

Easily found items I needed. Great prices!Super fast shipping. I am very pleased with my experience with Autoplicity. Only negative I experienced was when I went to check my order status it always gave an error message. But the item was shipped so quickly this really didn't cause too much worry.

Good Pricing

cheap.

THEY SENT THE WRONG PART ,I'VE SENT IT BACK AND STILL WAITING FOR MY REFUND!
