LSXcellence is here to support the LS crowd. And ONLY LS. We have no plans of expanding into other markets other than the very similar Gen V LT engines.

Working with only one engine brings a tremendous advantage to the customer and our business. We stick to what we know and have a large number of these builds on the streets. All with long term success.

Tuning, parts selection, machining, and assembly practices have all been documented and proven with well under a %1 failure rate. Our tuning procedures and engine assembly are extremely cautious and thorough. We attribute most of our success to these two core practices. Our confidence in the products and services allow for a rare warranty program in this high performance world. Your satisfaction is guaranteed.
