About this kit

Air Spring Kit with 4-Inch Lift Spacers, fitment-checked

Built for a Ram 1500 4WD that already sits on 4 inches of lift, Rough Country 100354 pairs the rear air spring kit with a matching 4-inch spacer set. Model years 2019 through 2026 are covered. Measure between the bump stop landing pad and the upper bump stop mount first, and confirm your rear measurement falls in the listed range before ordering.

Two parts arrive together: the Ram 1500 4WD air spring kit and a 4-inch lift spacer kit. Fitment covers 2019 through 2026 in Tradesman, Big Horn, Lone Star, Laramie, Longhorn, Limited, Tungsten, Rebel, Warlock, RHO, and Special Service trims. The spacer selection depends on your truck, so take the bump stop measurement before ordering rather than after the box arrives. Minor drilling is required during installation, and the air springs level a loaded truck without changing what it is rated to tow.
