How do these mounts improve driving feel and engine protection?

Mardarth uses an alloy steel frame with a resilient rubber compound to reduce engine movement and dampen road shocks. The design lowers vibration transfer into the cabin and helps maintain drivetrain alignment under load, which can extend life of connected components.

• Advanced rubber compound reduces NVH (noise, vibration, harshness).
• Alloy steel construction resists corrosion and deformation under heat.
• Absorbs shocks during acceleration, braking and off‑highway use.
• OEM-style mounting points for correct drivetrain geometry.

What components are included and which OE part numbers are replaced?

The kit ships complete with the three mounts you need to replace common front and trans support points. Mardarth lists many compatible OE references so you can match the part numbers to your vehicle’s current mounts.

• Included: Front left motor mount (84175583), front right motor mount (84175582), transmission mount (A2638).
• Replaces OEM numbers such as: A5739, A5738, A5668, A5735, A2638 and multiple EM/8417xxxx series.
• Check your vehicle’s existing part numbers against the full replacement list before purchase.

Can I install these mounts myself or should I use a professional?

Installation can be straightforward for experienced mechanics with proper tools and a safe lift, but mounting requires torque accuracy and engine support. For most DIYers lacking specialized equipment, a professional installation is recommended to ensure correct alignment and fastener torque.

• Recommended: professional installation if no mount experience or proper tools.
• Mechanics benefit from quick-fit OEM-style replacements to reduce shop time.
• Fleet or performance upgrades pair well with these mounts for reliability.

Who this is for: This Mardarth 3-piece mount kit is aimed at owners and technicians who need a dependable, OEM-compatible replacement for worn engine and transmission mounts on select 4WD V8 GM trucks and SUVs. Choose this kit if you want a direct-fit swap that restores engine stability, reduces cabin vibration, and maintains drivetrain alignment for everyday driving and towing scenarios.
