Citumo Engine Motor Mount Kit for Chevy GMC Cadillac 3‑Piece (A5365HY / 15854939) — Upgraded Rubber, Reduced Vibration

Citumo's 3-piece engine motor mount set (part A5365HY / 15854939) replaces worn mounts to reduce vibration and restore stable engine alignment for compatible Chevy, GMC, and Cadillac trucks and SUVs.

Over time factory rubber in engine mounts hardens, creaks, and transmits more engine movement into the chassis. This three-piece Citumo kit is made from upgraded materials engineered to withstand heat and road stress, restoring quieter operation and protecting driveline components on vehicles such as Tahoe, Silverado, Suburban, Avalanche, Sierra, Yukon, and Escalade (model years 2007–2014). The set includes three mounts and the reference numbers A5365HY and 15854939 for easy parts matching.

How will these motor mounts affect noise and vibration?

Replacing hardened or cracked mounts with this Citumo set reduces engine movement and the metal-to-metal contact that causes clunks and excessive vibration. Expect a noticeable drop in transmitted engine vibration under acceleration and while idling.

• Restores rubber damping that isolates engine noise from the cabin
• Reduces harshness during gear changes and throttle input
• Helps prevent premature wear on transmission and exhaust components

Are these mounts compatible with my vehicle?

This kit fits many GM full-size trucks and SUVs from 2007 through 2014—specifically Tahoe, Silverado, Suburban, Avalanche, Sierra, Yukon, and Escalade. Always verify your vehicle’s Year/Make/Model, engine displacement, transmission type, and original part number before purchasing.

• Reference part numbers: A5365HY and 15854939
• Compatible years: 2007–2014 for the listed models
• Check OEM fitment details or your vehicle’s service manual for exact match

What should I know before installation?

Installation is straightforward for a competent DIYer or a professional mechanic, but some models may require loosening nearby fasteners or removing heat shields so bolt holes line up. If a bolt cannot be aligned, slightly loosen the adjacent nut and remove the heat shield as instructed.

• Includes 3 mounts—inspect mounting hardware and replace if corroded
• May require temporary support of engine/transmission during swap
• Follow torque specs from vehicle manufacturer for secure installation

How durable are these Citumo mounts compared to stock?

Citumo uses improved rubber compounds and reinforced housings to resist hardening from heat and age, extending mount service life versus degraded original mounts. While longevity depends on driving conditions, these mounts are built to provide reliable vibration control and structural support under typical road stress.

• Upgraded rubber for better flexibility and vibration absorption
• Durable metal housings shorten the chance of premature failure
• Designed for direct fit to listed GM models for straightforward replacement

Who is this for? This Citumo 3-piece engine motor mount set (A5365HY / 15854939) is aimed at owners and technicians of 2007–2014 Chevy, GMC, and Cadillac full-size trucks and SUVs who are experiencing increased engine vibration, clunks, or visible mount wear. It suits DIY mechanics wanting a direct-fit replacement as well as repair shops needing a dependable aftermarket option to restore ride comfort and protect drivetrain components.
