Fit For GM LS Swap Transmission Mount Kit Polyurethane - 4.8 5.3 6.0 4l60e 4l80e

LS Swap Transmission Mount Kit for GM

This polyurethane transmission mount kit is built for GM LS swap applications, supporting 4L60E and 4L80E transmissions in 4.8, 5.3, and 6.0 liter builds.

Overview

This LS swap transmission mount kit provides a durable polyurethane mounting solution for GM LS engine conversions running 4L60E or 4L80E transmissions. The polyurethane construction offers firmer drivetrain control than rubber mounts while absorbing road vibration. It is aimed at builders swapping 4.8, 5.3, or 6.0 liter LS engines into project cars and trucks.

Built For Performance

• Polyurethane construction resists wear and drivetrain flex better than rubber
• Designed to position 4L60E and 4L80E transmissions in LS swap chassis
• Firmer mount reduces transmission movement under torque load
• Kit includes mount and hardware for straightforward installation
• Compatible with common 4.8, 5.3, and 6.0 liter LS engine swaps

Fits These Machines

• for GM LS swap vehicles with 4L60E transmission
• for GM LS swap vehicles with 4L80E transmission
• for GM 4.8 liter LS engine builds
• for GM 5.3 liter LS engine builds
• for GM 6.0 liter LS engine builds

On-The-Job Use

• LS engine swap projects in cars and trucks
• Transmission crossmember and mount fabrication
• Replacing worn factory transmission mounts in swapped vehicles
• Performance builds needing firmer drivetrain control

Specs At A Glance

Good To Know

Q: Will this mount fit my specific swap chassis? A: Fitment depends on your chassis and crossmember setup, so measure your mounting points before ordering. Polyurethane mounts are stiffer than stock and may transmit more vibration into the cabin.

Q: Is this kit compatible with both 4L60E and 4L80E transmissions? A: The kit is built to work with either transmission in LS swap applications. Confirm your transmission case bolt pattern matches the mount before installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
