ATZTNUO Body & Cab Mount Bushing Kit for 1999–2014 Chevy Silverado & GMC Sierra — Polyurethane Complete Replacement (Black)

ATZTNUO 7-141 Body and cab mount bushing kit replaces worn mounts to restore factory ride height, reduce cab movement, and tighten handling for 1999–2014 Chevy Silverado and GMC Sierra trucks.

If your Silverado or Sierra shows signs of body sag, excess vibration, or creaks between the cab and frame, this complete mount kit provides a durable replacement solution. Engineered from tough polyurethane, the kit replaces aging rubber mounts and associated hardware to return alignment and cabin stability without expensive dealer parts. The kit is tailored to many 1999–2014 1500 and select 2500 non-HD models and ships with upper and lower mounts, reinforced washers, and bolts for a straightforward swap.

How will these mounts change how my truck drives?

Replacing worn mounts reduces unwanted cab movement and body roll, which improves steering feedback and perceived stability. You’ll notice reduced vibration transmitted into the cabin and a firmer connection between body and frame during cornering or hauling.

• Polyurethane construction resists compression and tearing compared to old rubber.
• Tighter body-to-frame coupling reduces shimmy and wobble at speed.
• Less cabin vibration improves perceived quality and control.

Will this kit fit my Silverado or Sierra model year and drivetrain?

The kit fits most 1999–2004 Chevy Silverado 1500 and GMC Sierra 1500 models in both 2WD and 4WD, and it is compatible with some 1999–2004 2500 (non-HD) trucks. It is not recommended for 2500HD or 1500HD heavy-duty variants where longer bolts or different mounts may be required.

• Designed for 1999–2004 1500 series (2WD/4WD) and select 2500 non-HD frames.
• Check your vehicle’s current bolt lengths and HD designation before ordering.
• Not advised for heavy-duty models or certain aftermarket suspension setups.

What does the kit include and how easy is installation?

This complete kit supplies both upper and lower mounts plus reinforced washers and bolts so you can replace all body-to-cab points without sourcing extra parts. Installation generally requires standard hand tools and a safe method to support the cab while swapping mounts; professional installation is recommended if you’re uncomfortable working under the vehicle.

• Included: 8 upper mounts (68106), 8 lower mounts (68107), 8 reinforced washers (1163), 8 bolts (11516868).
• Replace mounts in pairs to maintain even ride height and alignment.
• Use torque specs and safety supports—cab-support jack or lift advised.

How durable are these bushings compared with original rubber mounts?

Manufactured from high-quality polyurethane, these bushings offer greater tear resistance and longer life than factory rubber mounts. They withstand oil, road grime, and seasonal temperature changes better, so they’re less likely to crack or sag over time under normal driving conditions.

• Polyurethane resists deformation and maintains shape under load.
• Reduced long-term sag preserves factory ride height and alignment.
• Durability helps prevent repeated premature replacements.

Who is this for: This kit is intended for owners of 1999–2004 Chevy Silverado 1500 and GMC Sierra 1500 (and select non-HD 2500) trucks who want to correct body sag, eliminate cab movement, and restore a firmer driving feel. It’s ideal for DIY mechanics who can safely support the cab and swap mounts, and for professional shops seeking a full replacement kit with matching hardware. If you have a heavy-duty model, custom suspension, or uncertain fitment, check vehicle specs or contact support before purchase.
