Jeremy Heaslip –
The holes circled in photo are smaller diameter than bolts provided, all bolts are too long. Will also need square washer to properly attach the part that is circled to shock mount. Still cheaper than maxtrac ones but will need all new bolts at proper length as well as washers. Will update after install.Update: returned item, not compatible with 07-13 sierra the part that is circled in pick is not long enough to reach opening and bolt onto shock mount. Also found the width was not wide enough to fit shock mount or shock.

No stars for a 2017 chevy silverado, they don’t fit, the Shock lower bushing won’t even fit where it should as the opening is too narrow. I don’t know what the may fit maybe the earlier version of the silverado, but absolutely won’t fit the 2017.
