Mardarth Engine & Transmission Mount Kit 3PCS for GM V8 4WD (Fits OE 84175582/583, A2638) — Steel-reinforced, Vibration-damping

This three-piece Mardarth mount kit replaces worn engine and transmission mounts (OE examples 84175582, 84175583, A2638) to restore secure powertrain alignment and reduce vibration.

Replacing failed motor mounts can stop excess engine movement, reduce noise, and prevent additional drivetrain wear. The Mardarth Engine Motor Mount & Trans Mount 3PCS kit includes the left and right front engine mounts plus the transmission mount engineered for compatible GM 4WD V8 automatic vehicles. Designed with alloy steel and a resilient rubber compound, these mounts match common OE fitments and are built to withstand temperature extremes and road shocks.

How will these mounts affect vibration and driving comfort?

These mounts use a durable rubber compound to absorb engine pulses and isolate road shock from the cabin. Expect reduced harshness during acceleration, smoother idle feel, and fewer transient clunks when shifting or accelerating hard.

• Advanced rubber formulation for effective vibration dampening
• Steel-reinforced construction to maintain alignment under load
• Designed to minimize engine movement during torque events

Which vehicles and part numbers does the kit fit?

The Mardarth kit fits many GM full-size trucks and SUVs with 4WD and V8 automatic transmissions from model years roughly 2015–2020. It is intended as a direct replacement for numerous OE part numbers so it installs like the original mounts.

• Compatible models include Escalade, Escalade ESV, Silverado 1500, Suburban, Tahoe, Sierra 1500, Yukon, and Yukon XL (specific engine and year restrictions apply)
• Common OE replacements: A2638, 84175582, 84175583 and dozens more included in fitment list
• Always verify vehicle fitment in your garage or with VIN before ordering

What’s included and how durable are these mounts?

The kit comes with two front engine mounts and one transmission mount, matching the original locations. Components combine alloy steel with tested rubber compounds to resist cracking, corrosion, and deformation under hot and cold cycles.

• Package includes: Front left motor mount (84175583), front right motor mount (84175582), transmission mount (A2638)
• Materials tested for thermal and environmental durability
• OEM-style fit and finish to simplify installation and longevity

Do I need a mechanic to install these mounts?

Professional installation is recommended unless you have the right tools and experience, because replacing mounts often requires supporting the engine and precise torqueing of hardware. Mechanics can complete the job faster and reduce risk of misalignment or damaged components.

• Recommended for experienced DIYers with engine support tools
• Professional shops ensure correct alignment and torque specifications
• Fleet or performance installations benefit from quicker turnaround

Who is this for: This Mardarth 3-piece mount kit is aimed at owners and technicians servicing 4WD GM V8 automatic trucks and SUVs from the 2015–2020 era who need a direct-fit replacement for common OE mounts. It’s a practical choice for fleet managers, restoration projects, or anyone replacing worn mounts to restore ride quality, preserve drivetrain components, and maintain factory alignment. Always confirm vehicle application prior to purchase and consult a professional installer if unsure about the removal or installation process.
