Citumo Engine Motor Mount Set for Chevy GMC Cadillac - Front Left & Right 15854939, V6/V8 Fit, Heat Shields

Citumo Upgrade Engine Motor Mount set (front left and right, P/N 15854939) replaces worn OE mounts to restore engine support and reduce vibration for compatible Chevy, GMC and Cadillac trucks and SUVs.

These replacement motor mounts are engineered to match original-equipment fit and function for model years that commonly experience rubber hardening and reduced vibration isolation. Each kit includes two front motor mounts with heat shields and direct-fit mounting points that correspond to several OE part numbers, making them a practical service item when engine movement, noise or accelerated drivetrain wear appears.

How will these motor mounts affect engine vibration and noise?

Replacing hardened or cracked engine-mount rubber with new mounts improves damping and reduces transmitted vibration to the chassis. You’ll notice firmer engine positioning during acceleration and fewer bangs or excessive movement when shifting or hitting bumps.

• New rubber restores vibration absorption lost to age and heat.
• Heat shields protect mounts from exhaust and under-hood temperatures.
• Direct-fit design aligns with factory mounting locations for consistent clearance.

Which vehicles and OE numbers are these compatible with?

The Citumo set fits a range of Chevy, GMC and Cadillac trucks and SUVs from the late 2000s to mid-2010s that use the specified motor-mount geometry. It is intended for V8 and V6 applications listed by engine displacement and model years—verify fitment against your VIN or factory part number before ordering.

• Common fits: 2007–2013 Escalade (ESV/EXT) 6.0L/6.2L and 2007–2013 Avalanche, Silverado 1500, Sierra 1500, Yukon 5.3L/6.0L/6.2L.

What should I know about installation and service notes?

Installation is intended to be straightforward for a qualified technician with basic hand tools and a vehicle lift or jack stands. Pay attention to the included heat shields: if bolts won't align, loosening the nut and removing the heat shield temporarily can ease installation.

• Includes front left and front right motor mounts plus heat shields.
• If bolt alignment is tight, remove the heat shield and retighten after positioning.
• Inspect surrounding brackets and fasteners; replace corroded hardware for best results.
