Finally a kit is underway for the nonSRT wk2 grand Cherokee. This rear diffuser will fit dual tips and fits all grand Cherokees with the stock bumper. Laredo, overland and limited. The OEM bumper does have to be modified but it's very simple. Professional install only. 
As with all products...theres a 15% cancellation fee and must be made before item is manufactured.
