ATZTNUO Body & Cab Mount Bushing Kit for 1999–2004 Chevy Silverado/GMC Sierra 1500 Red Polyurethane Restore Ride Height

ATZTNUO's 7-141 red body and cab mount bushing kit replaces worn mounts on 1999–2004 Chevy Silverado and GMC Sierra 1500 trucks to restore ride height, reduce body sag, and tighten chassis feel.

If your Silverado or Sierra has developed sagging bodylines, excessive vibration, or a loose feel between the cab and frame, worn rubber body mounts are often the cause. This ATZTNUO kit provides polyurethane replacements engineered to resist tearing and compression better than original rubber, returning the truck closer to factory alignment and reducing movement that causes noise and uneven handling.

How will these mount bushings affect ride quality and body movement?

Replacing aged mounts with rigid polyurethane parts reduces flex between the body and frame, which diminishes body roll and perceptible cabin movement. You’ll notice a firmer, more controlled feel during acceleration, cornering, and braking without adding suspension components.

• Red polyurethane reduces compression under load compared to old rubber.
• Minimizes body sag to restore factory ride height and sightlines.
• Less cabin vibration and rattles from improved vibration damping.

Will this kit fit my truck and what exactly is included?

The kit is designed for 1999–2004 Chevy Silverado 1500 and GMC Sierra 1500 in 2WD and 4WD applications and fits some non-HD 2500 models from the same years. It is not recommended for 2500HD or 1500HD variants that may need longer bolts or different hardware.

• Upper mounts (part 68106) x8 and lower mounts (part 68107) x8.
• Reinforced washers (1163) x8 and bolts (11516868) x8 included for complete replacement.
• Red finish for visual confirmation during installation and inspection.

What materials and longevity can I expect from these replacement mounts?

The components are molded from high-quality polyurethane formulated to resist tearing, oil, and weathering that commonly degrade OEM rubber mounts. That durability helps prevent premature sagging and maintains performance under towing or heavier loads when used within the kit’s compatibility limits.

• Polyurethane construction for increased tear and compression resistance.
• Engineered to withstand road salts, oils, and temperature cycling.
• Designed as a durable replacement versus stock rubber for longer service life.

Who is this for? This ATZTNUO 7-141 kit is intended for owners of 1999–2004 Chevy Silverado 1500 and GMC Sierra 1500 trucks (2WD/4WD) and select non-HD 2500 models who want to stop body sag, remove excess cabin movement, and restore alignment without changing suspension geometry. It’s aimed at DIY mechanics and professional installers replacing worn mounts; if you have a 2500HD/1500HD or an uncommon suspension setup, verify bolt length requirements before ordering.
