Mardarth Front Motor & Transmission Mount Kit for 07-13 Silverado Sierra 1500 (5.3L/6.0L/6.2L) — Direct-Fit, Durable Replacement

Mardarth front motor and transmission mount kit replaces worn mounting points on 2007–2013 Silverado and Sierra 1500 V8 trucks to restore engine stability and reduce vibration.

When an engine or transmission mount fails it transmits extra vibration into the cab, creates drivetrain noise, and can accelerate wear on connected components. This Mardarth kit provides direct-fit replacements engineered to match the original specifications for many 4WD V8 trucks (2007–2013 Silverado, Sierra, Escalade, Tahoe, Yukon XL) with 5.3L, 6.0L, or 6.2L engines. The parts are tested for durability and supplied as a package that includes both front engine mounts and the 4WD transmission mount.

Which vehicles and engines will this mount kit fit?

This kit is designed specifically for GM full-size trucks and SUVs from model years 2007 through 2013 with 4WD V8 powertrains. Use your vehicle’s exact year, model, and drivetrain to confirm fitment before purchase.

• Compatible models: Silverado 1500, Sierra 1500, Escalade, Tahoe, Yukon XL (4WD).
• Engine compatibility: 5.3L, 6.0L, and 6.2L V8 engines.
• Direct replacement for OEM numbers: 15854941 and 15840279 (also cataloged as A5365 and A2638).

How does this mount kit improve driving feel and component life?

Replacing degraded mounts re-centers the engine and transmission, absorbing torque reaction and isolating vibration. That reduces noise in the cabin, improves shift quality under load, and prevents accelerated wear on hoses, lines, and drivetrain joints.

• Restores original engine alignment to reduce drivetrain stress.
• Improves NVH (noise, vibration, harshness) for a smoother ride.
• Helps prevent premature failure of connected components.

What’s included and how does the kit match OEM standards?

The package ships with both front left and right engine mounts plus the front 4WD transmission mount. Mardarth manufactures these to meet or exceed the material and dimensional criteria of the original parts, and each unit undergoes quality testing prior to sale.

• Package contents: front left and right motor mounts (15854941) and transmission mount (15840279).
• Constructed from higher-grade raw materials to match OEM strength and fit.
• Backed by a 30-day warranty for initial peace of mind.

How do I install these mounts and what should I watch for?

Installation requires basic mechanical tools and a safe means to support the engine and transmission while mounts are swapped. Tighten fasteners to factory torque specs and inspect surrounding components for wear while the job is open.

• Support engine/transmission before removing old mounts to avoid misalignment.
• Replace bolts if they show corrosion or stretch; torque to OEM specifications.
• After installation, verify clearances for exhaust, hoses, and wiring harnesses.

Who is this for: The Mardarth front motor and transmission mount kit is aimed at DIY mechanics and professional technicians who maintain 2007–2013 GM full-size trucks and SUVs with 4WD V8 engines. It’s a good choice for owners who need a reliable, direct-fit replacement to cure excessive vibration, restore drivetrain alignment, or replace mounts that have reached the end of their service life. If you need exact fit confirmation, consult your vehicle’s VIN or use the provided part numbers (15854941, 15840279) to verify compatibility before ordering.
