Why S10 LS Swap Engine Mounts Are Necessary
When I decided to swap an LS engine into my S10, one of the first challenges I faced was how to properly secure the engine. The stock engine mounts simply weren’t designed to fit the LS engine’s size and configuration. Using the original mounts would have caused misalignment, excessive vibration, and even potential damage to the drivetrain over time. That’s why LS swap engine mounts are absolutely necessary—they ensure the engine sits correctly and securely in the engine bay.
From my experience, these mounts not only provide the proper positioning but also help maintain the correct angles for the transmission and driveshaft. Without them, I would have had to fabricate custom mounts or compromise the performance and reliability of the swap. The LS swap mounts are designed specifically for this application, making the installation cleaner, safer, and far more reliable. In short, investing in quality LS swap engine mounts saved me time, stress, and future headaches.
My Buying Guides on S10 LS Swap Engine Mounts
When I decided to swap an LS engine into my S10, one of the first challenges I faced was finding the right engine mounts. From my experience, engine mounts are crucial because they hold the engine securely in place and affect the overall performance and alignment of your swap. Here’s what I learned during my search and installation process.
Understanding the Importance of Engine Mounts
I quickly realized that engine mounts are more than just brackets—they absorb vibrations, maintain proper engine positioning, and prevent damage to other components. For an LS swap in an S10, the mounts must be specifically designed to handle the weight and torque of the LS engine while fitting the S10’s chassis.
Types of S10 LS Swap Engine Mounts
There are mainly two types I considered:
- Bolt-on Mounts: These are pre-fabricated mounts that bolt directly onto the S10 frame and LS engine. They’re the easiest to install and usually require no modifications.
- Custom Weld-on Mounts: If you’re looking for a more tailored fit or building a high-performance setup, custom mounts might be necessary. However, this requires welding skills or professional help.
I chose bolt-on mounts because they saved me time and provided a solid fit for my daily driver.
Material and Build Quality
The mounts I picked were made from heavy-duty steel with powder coating to resist rust and corrosion. This was important to me since I live in a humid area. Avoid mounts made from cheap or thin materials—they won’t last under the LS engine’s weight and torque.
Compatibility and Fitment
Not all LS swap mounts fit every S10 model year or LS engine variant. I double-checked compatibility with my specific truck year and the LS engine model. Many sellers list fitment info, but I also read forums and watched install videos to be sure. Getting mounts that don’t fit would’ve been a costly mistake.
Additional Components to Consider
Sometimes, engine mounts come as part of a kit including transmission mounts, hardware, and sometimes even crossmembers. I found it convenient to get a complete kit to ensure everything aligned perfectly and to avoid sourcing multiple parts separately.
Price vs. Quality
I balanced cost with quality—cheaper mounts might seem attractive, but I didn’t want to risk a failure or premature wear. Spending a bit more for a reliable brand gave me peace of mind during and after the swap.
Installation Tips from My Experience
- Make sure to lift the engine properly and secure it before removing old mounts.
- Test-fit the mounts before tightening all bolts.
- Use the correct torque specs to avoid damage or loosening.
- Check alignment thoroughly to prevent drivetrain issues.
Where to Buy
I found reputable engine mount kits from specialized LS swap suppliers online and local performance shops. Reading customer reviews helped me pick the best option for my build.
Final Thoughts
Swapping an LS engine into an S10 is an exciting project, and picking the right engine mounts is key for a smooth, reliable swap. From my journey, I recommend investing time in research, choosing quality mounts, and ensuring compatibility with your specific truck and engine. With the right mounts, your swap will run strong and last for years.
