Summary: This has worked great for me on my Jegs radiator. Dimensions were true and fitment was good. Used a little puffy tape to seal the cracks and hasnt needed adjusted since installed. Made a ton of difference in cooling, fan runs so much less.

Best shroud Rated by Down ranger on March 25, 2026
Summary: Great fan shroud fits perfectly
Yes, I recommend this product.
OUTSTANDING PRODUCT Rated by WEN on February 27, 2026
Summary: I was concerned regarding how this would arrive and then install since it is aluminum and would damage VERY easy in shipping. It arrived On TIME and was packaged very well to prevent damage from handling. In addition, it was completely covered on the finished side with a protective "peel off" coating. The dimensions I had to work with were VERY critical and it was ESSENTIAL for this to be exactly as advertised in order to fit. Low and behold, it was PERFECTLY sized and once I drilled the mounting holes it fit perfectly in place with NO additional alterations or fabrication of ANY sort.
I really had to modify this shroud. It must only fit one bra Rated by PastorFreddiek on November 05, 2025

No, I would not recommend this product.
I would buy this again Rated by Rob on October 03, 2025
Summary: I used this shroud to mount a 16" e-fan in my LS swapped BMW 750Li. My car would not stay below 180 degrees without it and now I can idle through pits and paddocks at 165 consistently.
Yes, I recommend this product.
