3mirrors Exhaust Insulator Hangers for Silverado Sierra Yukon Tahoe — 2-Pack Iron-Frame Core, OEM Fit

These are heavy-duty 3mirrors exhaust insulator hangers (OE 15092802) built with an iron-frame core and automotive-grade rubber to replace worn muffler mounts on select GM trucks and SUVs.

If your Silverado, Sierra, Yukon, Tahoe or compatible GM vehicle has sagging or rattling exhaust hardware, these 3mirrors insulator hangers are a direct-fit replacement designed to restore proper suspension of the exhaust system. Cast around a built-in iron frame and molded in premium rubber, each hanger is engineered to endure road stress while isolating vibration and reducing noise. They match OEM fitment for the listed model years and include practical installation tips to simplify swapping old, cracked hangers for new ones.

How do these hangers restore a noisy or sagging exhaust?

The hangers cradle the exhaust pipe and anchor it to the chassis, taking up play that causes dragging, clunks or resonance. Replacing aged rubber with a fresh insulator prevents metal-on-metal contact and stabilizes the tailpipe under load.

• Built-in iron frame prevents tearing and keeps shape under high heat and movement.
• Automotive-grade rubber dampens vibration and reduces exhaust noise transfer.
• Direct OEM-compatible dimensions for accurate pipe spacing and alignment.

Will these fit my vehicle and how easy are they to install?

These hangers are listed as compatible with 1999–2018 Chevrolet/GMC Silverado and Sierra 1500, 2000–2018 Yukon and Tahoe, 2003–2009 Hummer H2, and other models using OE numbers 15092802, 15740212 or 25956663. Installation is straightforward for DIYers with basic hand tools.

• Approximate size: 4-1/2" x 1-1/2" x 1-3/4", matching factory spacing requirements.
• Remove the old insulator, apply a small amount of grease or lube to ease removal and placement.
• Push the rubber into the hanger bracket and reseat the pipe—no welding required.

What makes 3mirrors hangers more durable than worn OEM pieces?

Durability comes from a cast iron internal frame fused with heavy-duty automotive rubber, a combination that resists tearing, heat hardening and deformation over time. The construction is intended to exceed OEM performance in harsh road conditions.

• Iron frame reduces risk of internal collapse and extends service life.
• Premium rubber compound resists cracking from heat, oils and salt.
• Manufactured to meet or surpass OEM fit and functional expectations.

How many hangers are included and which OEM numbers do they replace?

This listing includes two premium exhaust insulator hangers sized for direct replacement of common GM muffler/pipe mounts. They replace OEM part numbers 15092802, 15740212 and 25956663 where applicable.
