Happy with it.
With heavy front and rear steel bumpers got an immediate 2 1/2 inch in the front and 3 inch in the rear, but expect this to lower with time as the springs break in. Mechanic was impressed with the quality of the shocks, but had to modify the rear bracket holes to better align with the stock mounting holes. He also was not happy with how the front springs butted up to the yellow boot/spacer that came with it. Anyway, the lift was easy to install and the ride is much better than stock.
2010 Tundra suspension
Very happy with this suspension. Replaced my leveling kit and rear 3 inch leaf spring shackles with OMETUN57LKS. Brought the truck to factory stance and lifted the front about 3.5 inches and about 3 inches in the rear. The ride is a little stiff but not much more then when my TRD package was new. I also added SPC light racing adjustable UCA to achieve factory alignment. Differential drop was also added. It did take ARB 2 months to get the leaf springs and shackles in from OME in Australia.
