Anchor 300958 Engine Mount Kit

Engine Mount Kit Overview

Anchor 300958 is an engine mount kit built to support the engine and reduce vibration transfer. It is engineered to OEM standards and uses CAD/CAM-based design for consistent fit and quality. This kit is a direct service solution for BMW applications that need stable engine support and controlled noise isolation.

Key Features

• Engine mount kit for engine support and vibration damping
• OEM-standard engineering with CAD/CAM development
• Natural rubber and styrene butadiene rubber construction for abrasion resistance and aging stability
• Chemlock bonding agent for a stronger rubber-to-metal bond
• Rubber hardness matched to application requirements
• Hydraulic mount design used where OE calls for added vibration and torque control

Detailed Description

Anchor 300958 includes engine mount components identified as 1-10258 engine mount front left, 1-10259 engine mount front right, and 1-10236 transmission mount rear. The design focuses on supporting the powertrain while limiting vibration and noise, which is important in BMW 540i, BMW 740i, and BMW 840i applications. The use of natural and styrene butadiene rubber helps maintain abrasion resistance and long-term stability, while the bonded rubber-to-metal construction supports consistent performance under load. Anchor 300958 is a practical replacement choice when the original mounts have worn, softened, or separated.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

• Excess engine vibration felt through the chassis
• Clunking or movement from worn powertrain mounts
• Noise caused by deteriorated rubber isolation
• Loss of support from separated or collapsed mounts
• Harshness during acceleration or load changes

Installation Notes and Tips

Verify the mount layout against the vehicle before installation. This kit is listed for BMW 540i, BMW 740i, BMW 840i, and BMW 840i Gran Coupe applications, so confirm the existing mount configuration matches the part numbers in the kit. Inspect adjacent brackets and fasteners for wear or damage during replacement. Part number 300958 should be matched to the vehicle application before installation.

Quality Assurance

Anchor designs this mount kit to OEM standards using CAD/CAM engineering and application-specific rubber hardness targets. The construction uses natural and styrene butadiene rubber, along with Chemlock bonding, to support durability and consistent rubber-to-metal adhesion. Part number 300958 reflects Anchor's application-focused engineering for BMW engine mount service.
