Mishimoto MMRAD-SRT-15 Performance Aluminum Radiator for 2015-2020 Dodge Challenger SRT Hellcat

The Mishimoto aluminum radiator for the Dodge/Chrysler LX chassis is designed to provide superior performance and durability over the factory radiator, ensuring a lifetime of worry-free full-throttle pulls and daily driving.

Replace the fragile plastic end tanks on your Charger, Challenger, Magnum, or 300C's radiator with a robust, all-aluminum, fully-welded design. Forget plastic cracks or leaky hose fittings leaving you stranded on the side of the road or ending your track day early. With an all-aluminum design that boasts a 48% thicker core and a 222% increase in fluid capacity, the Mishimoto LX chassis radiator is built to withstand the toughest abuse. CNC-machined inlets and outlets ensure your hoses fit securely and without leaks.

Like all Mishimoto radiators, this radiator is a direct fit, simplifying installation—just remove the stock radiator and install your new Mishimoto aluminum radiator. Pair that quality and ease of installation with the Mishimoto Lifetime Warranty, and you’ll have the confidence to push your vehicle to its limits on the track and wherever else you need to go.

Key Benefits

50% thicker core and 0.5 additional gallons of coolant capacity over the stock unit prevents heat soak in the Challenger between runs—engineered for back-to-back pulls and track sessions.
1.96-inch-thick, two-row, furnace-brazed aluminum core provides ideal fluid temperatures on the street and track, running noticeably cooler than the factory unit under prolonged high-performance use.

Includes magnetic drain plug—captures harmful metal debris without additional tools for a complete installation.

All-aluminum construction with TIG-welded end tanks eliminates plastic factory components that fail under heat cycling from high-performance and supercharged Hemi engine use.

50% thicker, two-row, furnace-brazed aluminum core with increased fluid volume maintains consistent outlet temperatures during prolonged sessions and back-to-back pulls. Full compatibility confirmed for 2008 and 2011-2016 Dodge Challenger R/T 392, Scat Pack, SRT, and Hellcat—no cutting, modification, or adapters required.
Oversized core supports heat dissipation for stock and modified Hemi engines, including supercharged, turbocharged, and other modified Challenger engines.
Enjoy a lifetime of worry-free performance—backed by the Mishimoto Lifetime Warranty, your investment is protected long after installation.
