E-cowlboy Body & Cab Mount Bushing Kit for Chevy Silverado/Sierra 1999–2014 (Black, 24pc) Polyurethane Mounts & Plated Washers

This E-cowlboy 24-piece kit replaces worn body and cab mounts on 1999–2014 Chevy Silverado and GMC Sierra 1500/2500 (2WD/4WD) using high-density polyurethane and plated washers for longer-lasting alignment and vibration control.

If your Silverado or Sierra shows sagging body mounts, increased cabin vibration, or doors and panels that no longer line up, worn rubber mounts are often the culprit. This kit supplies eight upper polyurethane mounts, eight lower polyurethane mounts, and eight plated steel washers engineered as direct-fit replacements for trucks with oval upper mounts. It’s built to match OEM dimensions while upgrading material resilience for tougher, longer service life.

How does this kit improve ride comfort and noise control?

Upgrading from aged rubber to a high-density polyurethane compound reduces flex and deterioration that cause clunks and excessive movement. The firmer mounts maintain consistent body-to-frame spacing so panels, doors, and seals sit properly, which lowers wind noise and rattles without making the cabin harsh.

• Polyurethane resists oil, road grime, and UV better than original rubber
• Denser material reduces longitudinal and vertical body movement
• Cleaner body alignment minimizes door sag and panel gaps
• Includes plated washers to stabilize mount-to-frame connections

Will these mounts fit my Silverado or Sierra model and cab style?

The kit is designed for 1999–2014 Chevy Silverado and GMC Sierra 1500/2500 trucks with standard or extended cabs that use oval upper body mounts. Parts are produced to OEM sizing so installation follows factory mounting points and locations.

• Compatible with 2WD and 4WD chassis for specified years
• Includes upper (Part#68106) and lower (Part#68107) mount sets
• Works with trucks having oval-style upper mounts only
• Does not include metal sleeves or mounting bolts—reuse factory hardware or purchase new

What materials and durability can I expect from these replacements?

The mounts are molded from a premium high-density polyurethane blend formulated to resist deformation, cracking, and corrosion from common vehicle fluids. Compared with aged rubber mounts, these components hold shape longer and maintain their cushioning and holding power under load and temperature cycling.

• High-density polyurethane for increased wear life
• Impact and aging resistance to extend service intervals
• Plated steel washers included to prevent corrosive wear at fastener points
• Designed for consistent performance in road and weather exposure

How difficult is installation and what’s included in the package?

Installation follows the factory mounting locations and is a moderate DIY task for anyone comfortable lifting the body slightly and supporting the frame. The kit includes the polyurethane components and washers but not sleeves or new mounting bolts; technicians typically reuse serviceable hardware or add new sleeves as needed.

• 8 upper body mounts (Part#68106) and 8 lower body mounts (Part#68107)
• 8 plated steel washers (Part#1163) for secure fastening
• Does not include sleeves or mounting bolts—inspect and replace as required
• Returns accepted within 30 days; 12-month warranty from E-cowlboy

Who this kit is for: Vehicle owners or shops restoring proper body-to-frame alignment on 1999–2014 Chevy Silverado and GMC Sierra 1500/2500 trucks—especially those replacing deteriorated OEM rubber mounts who want a longer-lasting polyurethane upgrade. It’s ideal for trucks experiencing increased cabin vibration, door sag, or loose-feeling body fitment and for anyone who prefers parts made to OEM dimensions with improved material performance.
