The Supreme Suspensions lift and leveling kits for Nissan Frontier in brief

Supreme Suspensions offers lift and leveling kits for the Nissan Frontier, and two part numbers fit here: 284.3ST(pro) and 284.3ST(140)(pro). Both give 3 in of front lift with spacers, and both reuse the factory shocks. The first is front-only, built from two front strut spacers, with 0 in at the rear. The second adds rear high-strength steel lift shackles that sit 2 in over stock, for 2 in of rear lift. Both list 2WD and 4WD fitment on the Frontier from 2005 to 2021. The maker says the spacer thickness is 1.65 in, and that lift amount does not equal spacer thickness. Neither kit is compatible with Pro4X models. No largest tire size is published for either part number, and the maker says an alignment is always recommended after altering the height.

Which part number is yours

The two numbers split on one question: whether you want a rear lift. 284.3ST(pro) is the front-only kit, 3 in up front and 0 in at the rear, using two front strut spacers. 284.3ST(140)(pro) adds the rear high-strength steel lift shackles, 2 in over stock, which gives 2 in at the rear on top of the same 3 in front. The maker also lists 284.3ST(140)(Bump3)(pro), a variant with polyurethane UCA bump stops. All are listed for 2WD and 4WD. The maker's title says 2005-2023 and its web address says 2005-2020, so a 2022 or newer Frontier is not confirmed and fitment is stated for 2005-2021 only. Pro4X models are excluded. Match the full part number exactly as printed, including the (140) tag, since that is the version with the shackles. An alignment is always recommended after altering the height, per the maker.

    Supreme 284.3ST(pro) fits 2WD and 4WD trucks but not Pro4X models. Supreme's year ranges disagree (2005-2023 in the title, 2005-2020 in the web address), so it is shown for 2005-2021 only, and 2022 and newer Frontiers are not confirmed. The 1.65 in spacer thickness gives the 3 in lift, since Supreme says lift amount does not equal spacer thickness. Supreme 284.3ST(140)(pro) fits 2WD and 4WD trucks but not Pro4X models, and a variant with polyurethane UCA bump stops is 284.3ST(140)(Bump3)(pro). It has front high-strength steel strut spacers and rear high-strength steel lift shackles (2 in over stock). Supreme's year ranges disagree (2005-2023 in the title, 2005-2020 in the web address), so it is shown for 2005-2021 only, and 2022 and newer Frontiers are not confirmed.
