Frequently Asked Questions

What are LS engine parts?

These parts are commonly used in builds focused on durability, performance, and compatibility across a wide range of high-performance vehicles and setups.

Are LS engine parts interchangeable?

Many of the LS engine parts we sell share similar designs. This helps them be interchangeable across different LS platforms. You can check the fit on each page description. Keep in mind that fitment still varies depending on engine generation, modifications, and specific configurations. It’s important to confirm compatibility before installing parts on your setup.

Do LS performance parts require tuning?

Can LS parts be used for engine swaps?

LS parts are commonly used in engine swaps because of their wide compatibility and availability. Many components are designed to work across different setups, but fitment still depends on your vehicle, mounting points, and the supporting parts used to complete the swap.

How do I choose the right LS parts for my off-road vehicle?

To select the right LS part for your off-road vehicle, check the page description for the fitment details. You should always buy accessories and parts that support the off-road vehicle, plus are durable and reliable under stress.
