S & J Engines Warranty

7-Year/100,000 Mile Non-Prorated Warranty: As Good as it Gets!



Non Pro-rated Warranty vs. Pro-rated Warranty: What’s the difference?

The non pro-rated warranty is considered to be the most valuable form of a warranty, and S&J Engine’s warranty is very best in the business. Non Pro-rated warranty means you’ll enjoy the same level of protection for the entire life of the warranty – 7 Years/100,000 miles!

In contrast, a pro-rated warranty covers a smaller percentage of coverage as the engine is used and gets older. The moment you start using your engine, you’re losing coverage – and peace of mind. While our competitor’s prorate their warranties, we don’t. We believe that you deserve the finest remanufactured and replacement engine backed by the best warranty in the business!

Upgrade to our Premium Limited Warranty for additional coverage in out-of-pocket expenses for labor rates. For very little cost you now have your mechanic paid without touching your wallet again!

Our service pledge to you is as good as the quality of our engines. You deserve the same level of protection for the entire life of the warranty.
