E-cowlboy Body & Cab Mount Bushing Kit for Chevy Silverado/Sierra 1999–2014 — 24pc Black Polyurethane

E-cowlboy 7-141 is a 24-piece polyurethane body and cab mount bushing kit engineered to replace the OEM mounts on 1999–2014 Chevy Silverado and GMC Sierra 1500/2500 2WD and 4WD trucks.

This complete kit contains eight upper body mounts, eight lower body mounts and eight plated steel washers designed as direct-fit replacements for oval upper mounts used on standard and extended cabs. Manufactured to match OEM dimensions, the high-density polyurethane formulation aims to resist oil, road grime and aging while improving body-to-frame attachment and vibration isolation compared with worn factory rubber mounts. The set does not include sleeves or bolts; it is intended for owners doing a body mount refresh or restoration.

How will these polyurethane mounts change ride feel and noise?

Upgrading to polyurethane body mounts typically results in firmer body support and reduced sag from age-related rubber deterioration, which can lower squeaks and movement at the cab-to-frame interface. You may notice a slightly stiffer vibration signature because polyurethane is denser than original rubber, but the net effect is improved alignment and fewer clunks over rough roads.

• Reduces body shifting and clunking from loose or crushed OEM mounts.
• Polyurethane resists oil and degradation for longer service life.
• Provides more consistent cushioning and holding power versus old rubber.

Are these mounts a direct fit for my Silverado or Sierra?

Yes—this kit is made to match OEM specifications for 1999–2014 Chevy Silverado and GMC Sierra 1500/2500 with oval upper mounts, for both 2WD and 4WD, standard and extended cab models. The components are precision-molded to the same dimensions as factory parts so they install in the original mounting locations without modification.

• Includes 8 upper mounts (Part# 68106) and 8 lower mounts (Part# 68107).
• Supplied with 8 plated steel washers (Part# 1163) for proper load distribution.
• Does not include sleeves or bolts; reuse existing hardware if serviceable or replace as needed.

What materials and durability features does this kit offer?

The bushings are made from a high-density, specialty polyurethane blend chosen for tear resistance, impact strength and resistance to environmental factors that shorten rubber part life. Polyurethane maintains shape under load, resists corrosion effects from road chemicals and reduces long-term deformation common to aging rubber mounts.

• High-density polyurethane resists oil, road grime and UV exposure.
• Plated steel washers add corrosion-resistant bearing surface.
• Engineered to preserve cab alignment and reduce body-to-frame play over time.

What is included and what should I prepare before installation?

The package contains 24 pieces: 8 upper mounts, 8 lower mounts and 8 washers. It does not include sleeves or bolts, so inspect your existing hardware and sleeves and replace them if corroded or damaged. Basic hand tools and a vehicle lift or jack with safety stands are recommended for safe access to the mount locations.

• Kit contents: 8 × upper mount (68106), 8 × lower mount (68107), 8 × washer (1163).
• No sleeves or bolts included—plan to reuse or source replacements.
• Allow time for lift/jack setup, rusted fastener removal and proper torque when reassembling.

Who is this for: This E-cowlboy 7-141 kit is for Chevy Silverado and GMC Sierra owners, mechanics and restoration enthusiasts who need durable, direct-fit body and cab mount replacements for 1999–2014 1500/2500 trucks. It’s suited to anyone replacing aged, flattened or oil-soaked rubber mounts who wants longer-lasting polyurethane parts and improved body alignment. If you require sleeves or new fasteners, plan to add those items to your parts list before starting the job.
