This spring is as advertised, but does not fit my 2016 GMC Canyon without some serious modifications.
In order to remove the leaf springs, you have to either drop the gas tank, or cut the bolt and replace it going the opposite direction.
Disassembling the leaf pack to insert this spring required drilling out a hardened, seized roll pin that keeps the bottom springs from rotating.
This means you also have to drill a corresponding hole in the new leaf so that it will not rotate, and weld in a new pin that passes through 3-4 leafs.
The provided bolts are not long enough, it needs to be ~1/2" longer to pass through all of the springs.
Overall it was more work than I bargained for, and could not have been done without my convenient access to a fully equipped fabrication shop.
Be warned! You might get a bigger job than you bargained for.
Springs work great and gave me 1.5" of lift.

These springs fit like a glove. Compensated the weight of my shell and rack. Truck no longer bounces down the road.
