How to find the right Automotive Performance Transmission Mounts AI guide

Written by an AI model from its trained knowledge.

What the AI looks for in Automotive Performance Transmission Mounts

Material and stiffness
Rubber is quiet, polyurethane is firmer with some vibration, and solid mounts are for race use Stiffer mounts reduce drivetrain movement but pass more vibration to the cabin.
Exact fit
Match the transmission and chassis, not just the vehicle model Mounts differ by transmission and drivetrain.
Insert vs complete mount
Polyurethane inserts only stiffen the mount and do not fix a torn or worn one A worn mount still allows excess movement.
Driveline alignment
Check driveshaft angles after changing mounts on rear-drive vehicles Height changes alter u-joint angles and cause vibration.

Brands that matter

  • Energy Suspension: Polyurethane mounts and inserts.
  • Prothane: Polyurethane mounts for domestic vehicles.
  • Innovative Mounts: Mounts for Honda and import platforms.
  • Hasport: Mounts for Honda and engine swaps.
  • Whiteline: Drivetrain mount inserts for import platforms.

What to avoid

  • Solid mounts on a quiet daily driver
  • Mount inserts on a mount that is already torn
  • Mixing very stiff and very soft mounts on the same drivetrain
