Toytec TAC-DR-05 diff drop kit. It's designed to lower the front diff by 1" to improve CV angles in lifted applications. According to Toytec's website, this kit will fit the following 4x4 vehicles: 05+ Tacoma, 03+ 4Runner, 07+ FJ Cruiser.
I bought this to use when I installed my OME front lift, but never installed it. It's brand new in the box, I had to cut the tape off the box to take these pictures.
Price: $25 shipped via USPS Priority Flat Rate w/ tracking (payment via PayPal)....unless the buyer desperately wants the original box, I don't plan to ship the original box with the sale since it would require the next-size-up USPS box.
