Lowering Kit Builder Tool. The Easy Way to Build Your Lowering Kit

Upgrade the suspension on your 2015, 2016, 2017 or 2018 GMC Denali 1500 truck by lowering it.

 The Lowering Kit is available in the following configurations.

Leaving the front at the factory height, we can lower the rear by 2 or 3 inches with shackles and a shock relocator.

We can also lower the front by 2 inches with spindles while lowering the rear by 2 or 3 inches, with shackles and a shock relocator.

Kit Notes:

  • Shock Upgrade is not available for MagaRide equipped trucks
  • These kits do not fit trucks with Cast Steel lower control arms. They are designed for trucks with aluminum or stamped steel lower control arms.
  • Must use at least a 17" wheel when using spindles

As a general rule 2014 to 2016 GM Silverado/Sierra 1500 models could use any of the 3 styles of control arms and 2016 to 2018 models use aluminum control arms.

GM control arms

There are three different front suspension options on the 2014 to 2018 Silverado and Sierra 1500 series four-wheel drive trucks. You can tell the difference by looking at the lower control arms. We have a chart listed here to help you find the style that your truck has. The reason that you can’t mix and match between the suspensions is due to different ball joint sizes.

There is also the Magnetic Ride Control option (MagnaRide) On those trucks you can’t change the front struts but can still use a spindle.

There are also two different rear suspension options, with magnetic ride control (MagnaRide) or without MagnaRide. If your truck has MagnaRide you can not replace the rear shocks. For those trucks you can only use a shackle along with a set of shock relocators.

If your new Silverado or Sierra has the upgraded Magnetic Ride Control suspension option, the you are a bit more restricted in your lowering options. In the front the choice will be a set of lowering knuckles for 2” of drop. You can’t change out the strut because the MagnaRide front strut is electronically controlled.

In the back of a truck optioned with GM’s MagnaRide suspension you are once again limited by the electronic shocks. If you change the ride height the onboard computer will get incorrect readings, so you need to keep the ride height as close to factory as you can. We have found that a shock extender bracket that keeps the rear shock at a similar location to factory. Combine the shock extenders with a set of lowering shackles.
