Product Details

The rear lower engine mount on your classic Mk2 or B3/B4-platform VW is under extreme stress during hard launches, rapid deceleration, and aggressive gear changes. The factory voided rubber mount was designed for comfort, not performance. Under heavy motorsport use, this soft rubber allows massive amounts of engine deflection. This excessive drivetrain rocking leads to severe wheel hop, sluggish throttle response, and famously sloppy, missed gear changes because the shift linkage is physically pulled out of alignment by the moving engine.

Enter the Powerflex Black Series.

The PFF85-245B (often listed as PFF85-245BLK) Rear Lower Engine Mount Insert is engineered explicitly for dedicated track cars, autocross builds, and uncompromising high-performance street cars. Manufactured using Powerflex�s ultra-stiff 95A durometer Black Series polyurethane, this specifically molded insert is designed to slide directly into the empty voids of your existing original factory rubber mount (OE Part Number 191199262). By filling these gaps with motorsport-grade urethane, the insert severely restricts the amount of flex the rubber can achieve. This effectively stiffens the mount, drastically reducing drivetrain rocking and ensuring your power goes directly to the front wheels rather than twisting the engine in the bay.

Please Note: Because the Black Series compound is designed for maximum performance and near-zero deflection, installing this insert will result in a noticeable increase in Noise, Vibration, and Harshness (NVH) transmitted into the cabin. It is highly recommended for motorsport use!

Fitment Note: This is an insert designed to fit into a good-condition original rubber mount (OE Part Number: 191199262), located at Powerflex Diagram Position #20. It does NOT fit vehicles equipped with factory hydraulic (fluid-filled) mounts, such as 16v models (Engine Codes: KR, PL, 9A) or G60 models (Engine Code: PG). Please verify your mount type prior to ordering!

Key Benefits & Features:

  • Motorsport-Grade Precision: 95A durometer polyurethane drastically reduces engine rocking under heavy load, keeping your shift linkage perfectly aligned to eradicate sloppy or missed gear changes.

  • Maximum Power Transfer: Limits drivetrain movement so torque goes directly to the front tires instead of twisting the engine mounts, greatly reducing wheel hop and delivering immediate throttle response.

  • Cost-Effective Upgrade: Designed as a void-filler insert. It slides directly into the empty gaps of the OEM rubber mount (191199262) without the need for a hydraulic shop press or a complete mount replacement.

  • Bulletproof Durability: Impervious to blistering track temperatures, brake fluid, engine oil, and constant heavy drivetrain loads.

  • Quantity Supplied: Includes one (1) Black Series polyurethane insert kit. (Only one is required per vehicle).

  • Buy with Confidence: Even on track-dedicated components, Powerflex backs their products with an unconditional Lifetime Warranty!
