Mardarth Engine & Transmission Mount Kit for 1999–2006 Silverado Sierra Tahoe — 3-Piece V8 Fit (5.3L/6.0L) for Reduced Vibration

Mardarth 3-piece engine and transmission mount kit replaces worn mounts on 1999–2006 Chevrolet/GMC V8 vehicles to restore engine stability and reduce vibration.

If your Silverado, Sierra, Tahoe, Suburban, Avalanche, Escalade or Yukon has developed engine movement or excess vibration, this Mardarth kit provides a direct-fit solution engineered to match factory mounting points. The set includes two A2909 engine mounts and one A2638 transmission mount bundled for a straightforward swap that minimizes downtime and restores the drivetrain alignment critical for long-term component life.

Which vehicles and engines are compatible with this mount kit?

This kit is designed for a wide range of GM V8 trucks and SUVs built between 1999 and 2006, plus select later models noted for the same mounting layout. Check your vehicle year, model and engine size against the compatibility list before ordering to ensure a precise fit.

• 1999–2006 Silverado/Sierra 1500: 4.8L and 5.3L (4WD); 2001–06 6.0L (4WD)
• 2000–2006 Suburban 1500/2500 and 2000–06 Tahoe: 5.3L/6.0L and 4.8L/5.3L where indicated (4WD)
• 2002–05 Avalanche 1500 5.3L (4WD) and Escalade/Avalanche variations listed
• 1999–04 Silverado 2500, 2001–06 Silverado 3500, 2000–2006 GMC Yukon, and specific Hummer H2 application

How does this kit make installation easier for mechanics and DIYers?

Mardarth engineered the mounts to match OEM locations and bolt patterns so pieces drop into place with minimal modification. The kit’s guidance encourages common-sense steps that reduce installation errors and save time in the shop or garage.

• Loosely position all bolts first, then torque evenly to avoid misalignment.
• Slightly shifting the heat shield can provide the clearance needed for bolt access.
• Bundle includes the exact replacement part numbers to simplify ordering and verification.

What materials and part references support long-term performance?

These mounts are built from higher-grade raw materials intended to meet or exceed OEM durability expectations without changing engine geometry. The listing also includes cross-reference numbers to help you confirm compatibility with factory and aftermarket service parts.

• Premium construction for improved wear resistance versus cheaper aftermarket rubber mounts.
• Included part numbers: A2909, 2909, 605432, 605440, 15041508, 15226251, A2638 for cross-checking.
• Direct replacement design preserves factory alignment and drivetrain angles.

Will replacing these mounts change vehicle handling or drivetrain noise?

Replacing worn mounts typically reduces engine movement, which can lower driveline noise, vibration and harshness (NVH) but will not alter suspension geometry or steering behavior. Proper installation is essential to realize those improvements and to avoid introducing new vibration pathways.

• Restores intended engine position to limit stress on hoses, cables and exhaust.
• Can decrease perceived cabin vibration and improve shift feel when the transmission mount is renewed.
• Professional installation recommended if you lack torque tools or an engine support system.

Who is this for: This Mardarth three-piece mount kit is intended for owners and technicians working on late-1990s to mid-2000s GM full-size trucks and SUVs with 4.8L, 5.3L, 6.0L and select other V8 engines. It’s ideal for those seeking a direct replacement set that matches factory fitment, for fleet maintenance, restoration projects, or routine repair shops looking to minimize downtime. If you plan to upgrade engine components or perform gearbox service, replacing mounts with this kit helps protect other drivetrain parts and is a logical preventative step.
