I have been purchasing products from JASPER Engines and Transmissions for many years. They are everything they claim to be. You install the product, send it down the road and IT WORKS, no problems, no hassles. The product is the best on the market, and the installation kit is great, it saves time and makes the job a lot easier. Delivery is either exactly on time or early (wow). Cores are picked up promptly, and the driver does all the work (double wow). - Dave H.
