Tuff Country 1in Rear Block & U-Bolt Kit – 2011–2023 Chevy Silverado 2500HD/3500HD & GMC Sierra 2500HD/3500HD 4WD (97090)

Raise and fine-tune the rear of your Silverado or Sierra HD with the Tuff Country 1” Rear Block & U-Bolt Kit. This kit is designed to provide a slight rear lift while maintaining factory ride quality, making it a great option for correcting minor sag, improving stance, or dialing in suspension height.

This system includes heavy-duty cast lift blocks that install between the rear leaf springs and axle, along with extended U-bolts designed specifically for proper fitment. The bolt-on design allows for a straightforward installation without the need for major suspension modifications.
