Engine Motor Mount and Transmission Mount Kit Compatible

In this review the reviewer evaluates a three-piece motor mount kit designed for front installation on specific 2007-2009 Lexus RX350 and 2007-2010 Toyota Sienna V6 3.5L models. The bottom line: this kit is for the DIY owner or independent shop needing direct-fit replacements that aim to restore engine stability and reduce vibration. The reviewer found the parts matched the listed interchange numbers and appreciated the heat- and wear-resistant construction, making the kit a straightforward way to address worn mounts without costly dealer parts.

Key Features

• Vehicle Compatibility: Fits 2007-2009 Lexus RX350 and 2007-2010 Toyota Sienna V6 3.5L, so buyers with those models get a targeted replacement set.
• Complete Kit: Includes a front right engine motor mount, a front engine motor mount, and a front lower transmission mount so common front-mount failures can be addressed in one service.
• Interchange Numbers: Carries many interchange part numbers, which helps confirm fit by matching the old part numbers during installation.
• Durable Material: Constructed from premium material with good temperature resistance, which should reduce premature wear under normal driving conditions.
• Anti-Corrosion Coating: Treated with a corrosion-resistant finish to extend service life in humid or road-salt environments.
• Pre-sale Compatibility Check: The seller requests VIN or registration for fit confirmation, making it easier to avoid ordering mistakes.

Who It's For

This kit is best for owners of the specified Lexus RX350 or Toyota Sienna models who need direct-fit replacement mounts to reduce engine movement, vibration, or clunking during acceleration. It also suits independent mechanics who prefer a full front-mount solution in a single purchase.

It is not aimed at vehicles outside the listed years or engines, and buyers who cannot verify interchange numbers or prefer OEM-branded parts should look elsewhere or confirm fit with VIN details before ordering.

Pros & Cons
