Air Spring Kit with 4 Inch Spacer for Chevy & GMC HD (2020-2025)

Air Spring Kit with 4 Inch Spacer, fitment-checked

For the 2020-2025 Silverado and Sierra 2500 HD and 3500 HD, with a 4 Inch 4 Degree spacer and an onboard compressor. Two exclusions are specific to this generation: it does not fit trucks with a frame-side mounted fifth wheel hitch, nor trucks with a rear sway bar.

The current heavy-duty platform (Silverado and Sierra 2500 HD and 3500 HD, 2020 through 2025, in rear-wheel drive or 4WD) with the 4 Inch 4 Degree spacer kit and an onboard compressor with gauge. Two exclusions belong to this generation specifically and neither is obvious from looking at the truck: a frame-side mounted fifth wheel hitch rules it out, and so does a rear sway bar. Check both before ordering. The bags are double-convoluted, the kit does not raise the rated towing capacity, and minor drilling is required.
