Which part number is yours

The 453 codes are the Silverado leveling kits: 453.1(pro) at 2 in, 453.2(pro) at 2.5 in, 453.3(pro) at 3 in and 453.2(397.1)(pro) at 3.5 in. SUS-831620-SIL.1500-19-PRO is a 2 in strut spacer kit for 2019-2020 trucks, though the maker's own title says 2 in while the box list says 3 in spacers, so confirm what ships. The 294 codes are Sierra full lift kits. Read them as front lift plus rear block: 2F or 2.5F, then STB17, STB18 or STB19 for rear blocks of 1 in, 1.5 in or 2 in. On Z71 and LTZ trucks a factory block is replaced, so the net rear lift varies. Conditions to match, per the maker: 6-lug trucks only, no 2019+ Trail Boss, no AT4, and no Adaptive Ride Control, MagneRide, air ride or other self-leveling suspension. The maker recommends aftermarket uniball upper control arms on 2019+ models, and again when front lift is above 2.5 in.

Before you buy a lift kit

Questions owners ask

What lift sizes does Supreme offer for the Silverado 1500?

The 453 leveling kits give 2 in, 2.5 in, 3 in and 3.5 in of front lift, with 0 in at the rear. SUS-831620-SIL.1500-19-PRO adds a 2 in strut spacer option for 2019-2020 trucks.

Do these Supreme kits fit a Silverado with MagneRide or Adaptive Ride Control?

No. The maker says the kits are not compatible with Adaptive Ride Control, MagneRide, air ride or other self-leveling suspension. They are also for 6-lug trucks only.

Will a Supreme lift kit fit a Trail Boss or AT4?

The maker's conditions say the line does not fit the 2019+ Silverado Trail Boss, the Sierra AT4 or MagneRide trucks. Check the listing for the part number you want.

How much rear lift do the Sierra 294 kits give?

The rear block sizes run from 1 in to 2 in on the STB17 to STB19 kits and 3 in on the STB20 kit. On Z71 and LTZ trucks a factory block is replaced, so net rear lift varies.

Does Supreme recommend upgraded control arms for these kits?

Yes. The maker recommends aftermarket uniball upper control arms on 2019+ models, and again when front lift is above 2.5 in. One condition also says the kit does not fit OE stamped steel upper control arms.
