XLT Premium wheels & Bridgestone Dueler H/L Alenza tires (Very nice improvement over the smaller XLS tire/rim combo)
Rancho RSX shocks at all four corners (more firm than factory and much improved handling)
1.25" wheel spacers on front-end & 1.5" wheel spacers on rear-end (Spacers from Aim Industries http://www.truckn-store.com and are worth every penny as well.)
5% tint on front windows & 15% tint on back windows ( back windows ended up just a bit darker than the fronts, but looks nice overall.)
