HD Semi-Solid Engine Mount Set.

Enhance drivetrain precision and performance with the HD Semi-Solid Engine / Transmission Mount Set, designed specifically for Porsche 911 and 912 models
These heavy-duty mounts replace the factory rubber units with a semi-solid, high-durometer compound — around 25 % firmer than standard — providing improved control and response without sacrificing comfort.
The semi-solid design effectively reduces engine and gearbox movement under acceleration, braking, and cornering, giving sharper throttle response, smoother gear changes, and tighter handling stability.
Sold As A Set.
x2 Sets Required Per Car.

What This Product Does:

• In the Heavy Dusty semi-solid version, the stiffer rubber reduces unwanted flex while still providing some damping, hence a compromise between fully soft and fully rigid (solid) mounts.

Symptoms / Indications That Replacement Or Upgrading Is Needed:

• Engine / gearbox movement or “rocking” under throttle or deceleration
• Clunking or banging noises from the engine bay when shifting or applying torque
• Increased vibration in the cabin or floorboard
• Misalignment over time, causing stress or wear in driveshafts, couplings, or mount brackets
• Feel of looseness or lag in throttle response or drivetrain “lash”

Why Upgrading to HD Semi-Solid Mounts Matters:

• Sharper Response & Less Flex - Because mounts deflect less, the engine / gearbox stays more stable under load, improving throttle response, shift feel, and power delivery.
  
• Better Drivetrain Alignment - Less movement helps maintain correct angle relationships between engine, gearbox, driveshafts, etc., reducing stress and wear.
  
• Improved Stability Under Load - During hard cornering, braking, or acceleration, stiffer mounts help avoid drivetrain “twist” or slop, which can upset handling balance.
  
• Dampening Retained - Semi-solid design still absorbs vibration and noise more than fully rigid mounts, providing a balanced tradeoff for street use.
  
• Straightforward Installation - Because the inserts fit existing mount shells, installation is simpler — no need for custom brackets or drastic modifications.
  
• Good for Performance / Restoration Builds - Especially in cars that see spirited driving or occasional track use, the HD semi-solid mounts are a common upgrade that improves control without completely sacrificing comfort.

High Density engine/transmission mounts are the perfect compromise between stock rubber and our Semi-Solid mounts. Their heavy duty 25% higher durometer rubber construction makes them ideal for performance oriented cars, but still allows absorption of vibrations and noise associated with solid mounts. Installs in stock motor mount or transmission mount hangers replacing worn out factory rubber.
