Hello Dodge Magnum SRT8, Charger SRT8, Challenger SRT8 and Chrysler 300 SRT8 owners. Please do yourself a favor and buy these great ONE PIECE CHROME PLATED High Carbon Steel Nuts for your car - BEFORE you find out how terribly cheap "fake" acorn nuts are. The factory lugs will warp and tear the steel nut underneath (especially if the shops use an impact wrench and overtighten!) leaving you with a tire wrench that doesn't match what's left. These Gorilla Lug Nuts fit perfectly (13/16 wrench head) and are nice and deep and sit snugly in any wheel.
