In this review the reviewer evaluates a set of three replacement mounts intended for GM V8 4WD trucks and SUV models. The bottom line: this kit is best for owners of 2014-2020 Silverado, Sierra, Escalade, Suburban, Tahoe and Yukon XL models who need direct OE-compatible replacements and want a durable alloy steel and rubber assembly that reduces vibration. The review focuses on fitment, construction, and real-world value based on the kit's OE numbers and compatibility notes.

Key Features

  • Direct OE compatibility: The kit replaces multiple OEM numbers so buyers can expect straightforward bolt-in replacement for matching 4WD V8 automatic transmissions.
  • Broad vehicle fit: Compatible with specific 2014-2020 Silverado/Sierra, 2015-2020 Escalade, 2018-2020 Tahoe/Suburban and Yukon models, reducing the risk of ordering the wrong part when fitment is checked first.
  • Alloy steel and rubber construction: The combination of alloy steel and rubber is designed to absorb shocks and reduce engine vibration for improved ride comfort.
  • Temperature tested materials: The mounts are claimed to be tested under extreme cold and hot conditions to resist cracks and deformation over time.
  • Complete kit: The package includes front left, front right motor mounts and a transmission mount, avoiding the need to buy separate pieces.

Who It's For

This mount set is aimed at owners and DIY mechanics working on 4WD V8 GM trucks and full-size SUVs with automatic transmissions who need an OE-replacement style solution and prefer a complete kit for front left, front right and transmission mounts. It is useful for routine replacement where worn mounts are causing excess engine movement or vibration.

It is not intended for 2WD vehicles, non-V8 engines, manual transmissions, or models outside the listed years and engine sizes; those buyers should confirm fitment with their vehicle garage or dealer before ordering.

Pros & Cons

Pros

  • Direct replacement for many OEM part numbers, simplifying installation for compatible models.
  • Solid alloy steel and rubber build that aims to reduce vibration and engine shock transfer.
  • Sold as a set of three so owners replace all primary mounts together for balanced performance.

Cons

  • Fitment is limited to 4WD V8 automatic models, so verification is required before purchase.
  • No vehicle-specific installation hardware or instructions included in the product description, so some buyers may need professional installation help.
