Wheel fitment and kit notes: this kit requires cutting your truck's subframe for proper fitment and will not fit factory 18" or 17" wheels. This kit REQUIRES at least an 18x9" wheel with a maximum of 4" to 5" of backspace. All 18x9" wheels should be test-fit prior to installation, due to design variations that can cause fitment issues. For all other fitment questions, please contact Stage 3 directly at 623-434-5277.
