If buying new..I'd pass on the TRD package. The TRD Bilstein shock are wimpy. Get the Bilstein aftermarket shocks and save. The locker rear...well..If you know how to 4wheel you shouldn't notice a difference. I don't have it and have never had any problem yet. Stickers. Here's a site to get any ones you want. The progessive springs are nice in the front especially if you add spacers for lift. Buying used.. I believe a TRD package adds about $300 in the blue book.
Opps.... The sticker site...can't forget about those stickers..
