Just did a weekend trip to Cape May, 4hr+ each way, the jackers made a noticeable improvement in my ability to be comfortable driving in the seat, less sciatica acting up and none of the pain I'd get in my right thigh from lack of support when pressing on the gas pedal. I'm 6'1", 33" inseam for reference. Wish they were a tad cheaper tho, like closer to $50, thus 4stars not 5.
I own a tundra. If it had not been for a Video of Tacoma install, I would have struggled. No video for a Tundra. If you change the bends slightly on the mounting plate then you wouldn't need the seat jackers for this install. Tundra doesn't really need them in the first place. Seats are high enough. Looks very good when finished.
I installed the seat jacker (bundle) kit for a Tacoma on my Prius driver's seat so my wife could see better. And better it was, no more cushions to raise her up. It's even good for me.
