Don't recommend
Went through all the trouble of removing wheel, taking out the sway bar and rear strut and then lowering the axil to get the spring out only to find out that even though they claim it fits 2003-2020 4runner, it does not fit my 2011 4runner. Waisted my time and money. Won't buy from this company again.

Terrible product, do not buy it. Is a gotcha!
In the post it says it is a rear lift kit but it is not. This product is not for installation in any way. Is a gotcha. Amazon should not allow this company to sell its products around here.

Great quality product
The spacers are high quality aluminum and the nuts are all threaded with locking for no rattle fit. The bolts are GU F 8.8 metric grade, with a matching width to the OEM bolts and fit with the same thread if you don't want to use the nuts for some reasons. The grade of the bolt is on the lower end for metric standards, but the OEM don't have a rating I can read. overall the cost for quality can't be beat.
