E-cowlboy Body & Cab Mount Bushing Kit — Black 24PC Polyurethane for Silverado/Sierra, Direct-Fit NVH Reduction

These 24-piece E-cowlboy polyurethane body and cab mount bushings and washers are a direct-fit replacement for 1999–2014 Chevy Silverado and GMC Sierra 1500/2500 standard or extended cabs, designed to restore body-to-frame alignment and reduce noise and vibration.

If your truck’s cab sits unevenly, you hear extra rattles, or the factory mounts have flattened with age, this complete kit replaces upper and lower mounts plus plated washers to return secure attachment and cushioning. Engineered to OEM dimensions but molded from high-density polyurethane, the set resists oil, road grime, and typical wear better than old rubber mounts. It’s sold as a 24-piece set: 8 upper mounts (part# 68106), 8 lower mounts (part# 68107), and 8 plated steel washers (part# 1163). Sleeves and bolts are not included.

Will these mounts fit my 1999–2014 Chevy Silverado or GMC Sierra?

Yes — this kit is tailored for Silverado and Sierra 1500/2500 models with oval-style upper mounts in both 2WD and 4WD, standard or extended cabs. Each piece is manufactured to match OEM mounting geometry so they install in the factory locations without modification.

• Compatibility: 1999–2014 Silverado & Sierra 1500/2500
• Cab types: Standard and extended cab with oval upper mounts
• Drive options: Works for both 2WD and 4WD
• Replacement: Direct-fit for original mount locations

How do polyurethane mounts compare to the factory rubber ones?

Polyurethane is stiffer and more durable than typical rubber, so these mounts maintain shape under load and handle exposure to oil, salt, and road contaminants better. Expect improved resistance to deformation, slower aging, and greater holding power while still offering cushioning to reduce vibration.

• Material: high-density polyurethane blend for long life
• Performance: better impact and corrosion resistance than rubber
• NVH: helps reduce squeaks, rattles and excessive movement
• Durability: aging and chemical resistance for extended service

What is included in the kit and what will I still need?

The package supplies everything required to replace the upper and lower body mounts and the mating washers for a full set of mounting points on one truck. It does not include metal sleeves, bolts, or other fasteners, so you may reuse existing hardware if undamaged or purchase new sleeves/bolts when necessary.

• Included: 8 upper mounts (68106), 8 lower mounts (68107), 8 plated washers (1163)
• Not included: sleeves, mounting bolts, or installation tools
• Installation tip: inspect original sleeves and bolts; replace if corroded
• Fitment note: installs in OEM mount locations without modification

How long can I expect these mounts to last and what warranty is offered?

Service life depends on usage and environment, but polyurethane typically outlasts original rubber under the same conditions. E-cowlboy backs the kit with a 12-month warranty and a 30-day satisfaction return policy so you can test fit and performance risk-free.

• Longevity: superior wear and aging resistance versus rubber
• Protection: 12-month limited warranty from E-cowlboy
• Return policy: 30-day money-back guarantee if unsatisfied
• Support: customer service offered for fitment and returns

Who is this for: This kit is aimed at Chevy Silverado and GMC Sierra owners (1999–2014 model years) who want a durable, direct-replacement solution to worn body mounts — particularly those restoring older trucks, repairing sagging cabs, or upgrading to polyurethane for longer life and reduced body movement. It’s also a practical buy for mechanics and restoration shops that service classic model-year Silverados and Sierras and prefer OEM-fit parts with enhanced material performance.
