Springs for Silverado & Sierra 1500, Incl. ZR2 & AT4X

Springs, fitment-checked

this part spells out its trims rather than leaving them open, and the off-road flagships are on it: ZR2 on the Chevrolet side, AT4X on the GMC side.

Where a blank trim field leaves room for doubt, this fitment names them, and the ones worth noticing are ZR2 and AT4X: the factory off-road trims that most half-ton listings exclude. The Chevrolet Silverado 1500 runs Custom, Custom Trail Boss, High Country, LT, LT Trail Boss, LTZ, PPV, RST, SSV, the WT variants and ZR2. The GMC Sierra 1500 runs AT4, AT4X, Base, Denali, Denali Ultimate, Elevation, Pro, SLE and SLT. Both span 2019 to 2024, stopping before the newest trucks.
