Whiteline Front Transmission Mount Insert Bushing Kit

Multiple Subaru Models with 2.0L and 2.5L Engines (Years Vary)

Part #: KDT984

Overview

The Whiteline Front Transmission Mount Insert Bushing Kit is designed to enhance the driving experience of Subaru enthusiasts by reducing transmission slop and improving response. Factory transmission mounts prioritize comfort and vibration dampening, which can sometimes lead to a feeling of sluggishness or delayed response during spirited driving or aggressive throttle inputs. This kit addresses those issues by filling the voids in the stock mounts with high-performance polymer inserts, resulting in a more direct and crisp transmission feel.

Ideal for Subaru owners who seek a more engaged driving experience without sacrificing daily comfort, this kit is perfect for street-driven cars, autocross enthusiasts, or anyone looking to sharpen their vehicle's shift response. By removing excess movement and slop from the transmission mount, you'll notice quicker throttle response, improved shift feel, and a more connected driving sensation.

Key Features

Whiteline's Front Transmission Mount Insert Bushing Kit is engineered with precision to deliver noticeable improvements in vehicle response and handling. The key features include:

• Constructed from low-compliance, high-strength polymer material that fills voids in the stock rubber mount, reducing unwanted movement.
• Designed specifically for Subaru models with 2.0L and 2.5L engines, ensuring a perfect fit and optimal performance.
• Helps eliminate transmission slop, resulting in a more direct and responsive feel during acceleration and deceleration.
• Manufactured with high-quality materials that withstand heat and engine bay conditions, ensuring durability and long-lasting performance.
• Simple bolt-in installation that requires no modifications or special tools, making it accessible for DIY enthusiasts and professional installers alike.
• Reduces the lag in response caused by factory rubber mounts, providing a more engaging driving experience.
• Designed to complement other drivetrain upgrades for enthusiasts seeking maximum responsiveness.

Construction & Design

The Whiteline transmission mount insert kit features a high-grade polymer compound that is engineered for low compliance and high durability. The inserts are precisely machined to fill the voids in the factory mounts, effectively stiffening the mounting points without adding excessive NVH (noise, vibration, harshness). The design ensures a snug fit that minimizes movement while maintaining the integrity of the transmission mount assembly.

Manufactured with attention to detail, these inserts are resistant to heat and engine bay contaminants, ensuring consistent performance over time. The kit's design maintains the balance between improved response and comfort, making it an ideal upgrade for daily drivers and performance-oriented vehicles alike.

Installation & Fitment

The installation process is straightforward and requires no cutting or drilling. The kit is designed as a bolt-in upgrade that fits directly into the existing transmission mount assembly. Basic hand tools are sufficient for installation, and no special tuning or adjustments are necessary. The process typically involves removing the existing mount, inserting the polymer bushings into the voided areas, and reassembling the mount. This simple upgrade can be completed in under an hour, making it accessible for DIY enthusiasts and professional mechanics alike.

• No cutting, drilling, or complex modifications required.
• Compatible with multiple Subaru models equipped with 2.0L or 2.5L engines.
• Designed for street and spirited driving applications.
