Description
Product Overview
The Energy Suspension 3.1120G Complete Engine and Transmission Mount Set is engineered for drivers who demand reliable performance and lasting durability. Housed in a precision‑machined black aluminum shell, each mount incorporates Hyper‑Flex replacement polyurethane components that resist contaminants, resist permanent compression, and maintain consistent damping characteristics over the life of the vehicle. The set includes one engine mount and one transmission mount, each weighing only 6.1 ounces, yet delivering the strength needed to support a wide range of passenger cars and light trucks. With a compact 9‑inch depth and a 4 × 9 × 9‑inch footprint, the mounts fit seamlessly under the vehicle, preserving ground clearance while providing a secure anchor point for the powertrain.
Usage
Designed for under‑vehicle mounting, this set is ideal for both OEM replacement and performance upgrades. Whether you are restoring a daily driver, preparing a vehicle for spirited weekend driving, or addressing excessive vibration after a repair, the 3.1120G mounts deliver a smooth, controlled ride. They perform well in diverse climates, thanks to the polyurethane’s resistance to oil, coolant, and road grime, making them suitable for commuter traffic, highway cruising, and light track use. Installation requires standard hand tools and follows the original mounting points, ensuring a straightforward swap for DIY enthusiasts and professional mechanics alike.

FAQ
Will these mounts fit my vehicle if I have a different engine model?
The 3.1120G set is designed to match the OEM specifications for a range of makes and models that use the original part numbers 3‑1120G or 3-1120G. Check your vehicle’s service manual or contact our support team with your VIN to confirm compatibility.
Can I install the mounts myself, or do I need a professional?
Installation is straightforward and uses the existing mounting bolts and brackets. With basic hand tools and the included torque specifications, most DIYers can complete the swap in 1–2 hours. However, if you are unfamiliar with engine or transmission work, professional installation is recommended.
How does the Hyper‑Flex polyurethane compare to traditional rubber mounts?
Hyper‑Flex polyurethane offers higher resilience to heat, oil, and chemical exposure, and it does not compress permanently like rubber. This results in longer service life, consistent vibration damping, and reduced noise over time.
What warranty does Energy Suspension provide for this mount set?
The 3.1120G mount set comes with a limited 2‑year warranty covering manufacturing defects. Registration on our website is required to activate the warranty and receive support.
Are these mounts suitable for track or high‑performance applications?
Yes. While they are designed for daily driving, the robust construction and high‑performance polyurethane make them a solid choice for light track use, providing improved stability and reduced drivetrain movement.
