2 Inch Block & U-bolt Kit | Chevy/gmc 1500 2wd/4wd (99-24)

Built for Chevy and GMC 1500 owners who want to level their truck and accommodate up to 33-inch tires — this 2-inch block and u-bolt kit corrects rear suspension sag and restores the aggressive stance your truck deserves. Rough Country's tapered nylon composite blocks reduce driveline angle for smooth driveshaft geometry, backed by a full set of corrosion-resistant steel u-bolts.

Installed and serviced at Road Runner Wheels & Tires. Most suspension upgrades go in the same day. Call (678) 400-6467 to schedule.

What's included

• Fiberglass reinforced nylon blocks (pair) — tapered design reduces driveshaft angle and delivers superior strength over cast alternatives. Single 9/16-inch pin snugly fits your factory axle pad.
• Steel u-bolts with e-coat finish (set) — 9/16-inch thread size, 2.5-inch inside width, 9.5-inch inside length with square style for secure rear-axle attachment. Four inches of thread ensures plenty of engagement.

Important notes

• Does NOT fit models equipped with composite leaf springs — verify your truck uses traditional steel leaf springs before ordering.
• Recommended tire range is 32–33 inches to maintain proper suspension geometry and ride quality.
