Run Cooler. Keep your high revving 4.6L manual Mustang running cooler for maximum power on the street, strip or track, with an all aluminum SR Performance radiator.

The superior construction of this SR Performance Radiator allows it to withstand the high pressures and abuse of everyday daily driving as well as occasional weekend track use.

Will this fit with my vortech supercharger you have to trim the fan shroud quite a bit with the stock radiator I just don't want to buy something that won't fit


  • The SR Performance Aluminum Radiator is compatible with the Vortech supercharger, however some additional trimming of the fan shroud may be required.

when comparing the overall dimensions of the 96 radiator to the 97 shows that the 97 may fit in the 96. Seeing as the core is larger on the 97 can this radiator be used in place off the 96 on my Cobra?


Is there a manufacturers warranty on this product? If so how would i contact the manufacturer?


  • The SR Performance Aluminum Radiator does not come with a manufacturers warranty, but American Muscle does offer a 30 day warranty on all of its products.

    Best radiator ever

    Shipping was super fast on the radiator. after getting it, pulling it out of the box was amazing. It was just like an early Christmas present! It is truly an amazing radiator. When installing the radiator we had to take the battery tray out to help it fit, also had to bend the abs line just a little but not to bad. but it was not difficult at all. After installing the radiator and filling the car up with fresh coolant, I could see a huge difference in the cooling system. I would 100 recommend this product to anyone

    Would not recommend

    Bought this rad end of July and it didn't even last a year before it started leaking on the inside passenger words along the side. It ended up getting worse over a 2 week period and after I took the car to the shopit was loosing 1/2-2/3 a gallon of coolant a day. It ended up being cracked in 4 places. Don't waste your money on a rad that has no warrenty to speak of and only a 30 AM one. OEM is the way to go unless your making big power....

    Would not recommend.

    Bought this last July and didn't make it to December before it was leaking from the welds. I personally love AM products and have spent quite a bit of money on this site over the last few years. I have a had no problems until now. I just would not recommend this radiator as it has no manufacturer warranty and only an AM 30 day warranty. Product should definitely last more than 5 months! Again, love this site and products, but just not this particular item.

I drive the car to school and back. I don't know what to do now. I can't efford other $230 and I don't know if it has a warranty on it or not.

    I ordered the SR Performance radiator and was a little worried about how well it was going to fit. When it arrived, I went right out to install it.....all I can say is,...PERFECT... it went without any modification at all. After the install, I noticed right away how much lower my temperature gauge was reading. The design and construction of this item was second to none. Everyone should upgrade their cooling system, because a cool running a happy running Mustang. Thanks American Muscle. I look forward to my next purchase.

    Great looking radiator

    I went to install this radiator and like a few others I had issues getting it to drop right in. When I went to install it the top brackets were out by about an inch. I removed the large rectangular wire harness conduit that runs along the top of the radiator support and wrapped the harness in some 3/4" black loom. Once that conduit was out of the way the brackets fit no problem. I also had to bend back my abs lines about half an inch to clear my stock fan. All in all it was a great purchase for the money.

    Performance 100525 SR Performance Aluminum Radiator

    I bought this SR Radiator for my turbo Mach 1, because the stock Ford one couldn't keep up with the heat generated by the turbocharger. This radiator is much thicker than the stock unit! so dont expect it to drop in without modifications! After removing the stock radiator, i proceeded to install the SR Performance radiator, it wouldn't fit! because it was interfering with the ABS unit! I removed the bracket holding the ABS assembly, I then redrilled the the ABS bracket so that it would move the assembly 1/2" back towards the engine. I then test fit the radiator and it was no longer hitting the ABS unit, but the top radiator mounting brackets would not fit in there stock locations! they will also need to be drilled and taped if you want this thing to fit. Overall the radiator keeps my car much much cooler. Thanks American Muscle:)

    started leaking

    Installed last fall. Only driven a few thousand miles. I started to notice a small pool of coolant after running. Recently it has gotten worse. I'm now afraid to drive my car for fear of overheating. Guess I should have just kept the oem radiator!

    Looks great, tight fit!

    Radiator looks great and fit well, other than the tight squeeze getting the stock fan tucked between the radiator and the ABS module. Went for a test drive after install and everything seems great so far! I'll probably get the slim fan with shroud soon.
