Tuff Country 97090 Block & Ubolt Kit - 1" (H) x 2 1/4" (W) x 6 1/2" (L) Non-Tapered
Product Details
Description
Lift the rear of your Chevy Silverado 2500HD (and GMC Sierra 2500HD/3500) 4WD by 1 inch with the Tuff Country 97090 Block & U-Bolt Kit. This bolt‑on rear lift kit preserves factory ride quality while delivering a practical lift for payloads and towing.
- Rear lift height: 1" lift to restore or optimize rear stance under load without changing front geometry.
- Block material: Heavy‑duty cast iron lift blocks (some kits may include aluminum blocks depending on production run).
- U‑bolt set: Extended zinc‑plated rear u‑bolts designed specifically for the Chevy Silverado 2500HD to ensure a secure, durable mount.
- Fitment: Directly compatible with 2011–2019 Chevy Silverado 2500HD/3500 4WD and 2011–2019 GMC Sierra 2500HD/3500 4WD.
- Installation: Simple bolt‑on installation that spaces the blocks between the factory rear leaf springs and axle, using the factory mounting points.
- Dimensions: Lift blocks measure 1" (H) x 2 1/4" (W) x 6 1/2" (L); u‑bolts sized for secure alignment (dimensions: 3/5" x 3 1/4" x 12" – Square).
- Shocks note: When installing rear blocks 2" in height or taller, factory length shocks may need to be replaced with extended length shocks to maintain ride quality and safe handling.
- Safety & compatibility: Designed for rear axles only; never use lift blocks on the front axle. Zinc plating provides corrosion resistance for everyday use.
This kit is a practical solution for trucks that carry heavier loads or tow trailers, helping to restore a level stance and maintain comfortable control without compromising the factory ride. The robust cast blocks, paired with purpose‑built extended u‑bolts, deliver a reliable, long‑lasting retrofit that’s simple to install for a weekend project.
