Tuff Country 97033 Block & Ubolt Kit - 1 1/2" (H) x 2 1/2" (W) x 4 1/2" (L) Non-Tapered

Raise the rear of your GMC Suburban with confidence using the Tuff Country 97033 Block & U-Bolt Kit. This bolt‑on kit is engineered for GM full‑size SUVs and trucks, delivering a steady 1.5‑inch rear lift for improved stance, payload handling, and overall road manners.

• Lift Height: 1.5" rear lift using non‑tapered lift blocks with dimensions 1.5" (H) x 2.5" (W) x 4.5" (L).
• Block Material: Blocks are built for durability; depending on the kit, you may receive heavy‑duty cast blocks or aluminum blocks.
• U‑Bolts: Extended zinc‑plated rear u‑bolts designed specifically for the GMC Suburban to replace factory hardware.
• Compatibility: Designed for rear axles only; fits 1988–1998 GM 4WD models, including Suburban, Tahoe/Yukon variants, and corresponding K series pickups listed in the fitment notes.
• Installation: Simple bolt‑on process by inserting the blocks between the factory rear leaf springs and axle; no welding required.
• Shocks Consideration: For blocks 2" in height or taller, factory shocks may need to be replaced with extended‑length shocks to preserve ride quality—consult the Shock Absorbers section for applicable applications.
• Corrosion Resistance: Zinc‑plated hardware and u‑bolts provide improved resistance to rust and road salt.

The 97033 kit is purpose‑built for the rear suspension, helping you achieve a balanced stance whether you’re towing, carrying gear, or simply want a more level look. The combination of solid lift blocks and purpose‑matched u‑bolts ensures a secure, factory‑like ride with the added benefit of durable hardware designed for GM’s 4WD lineup from the late 1980s through the late 1990s. Whether you’re upgrading for clearance or aesthetics, this kit offers a practical, bolt‑on path to a steadier rear end on your GMC Suburban.
