Jasper Engines USA

Horrible company. The engine failed within the first 40 minutes of breakin and test drive. The engine started and ran for a short period of time then the misfires started to happen. Problem #1.

Great shop, Leonard took care of me with the purchase of a Jasper 5.3, I could not be happier with experience and customer service! Great people, great shop, great work! The sales rep for jasper, happened to be there while I was there and walked me through the entire warrant process as well! Definitely a good purchase!

Great mechanic' s! They put a remanufactured engine in my 2010 gen 5 Camaro. Im was happy with the price and service. They really made sure everything was solid.

Had an engine replaced, completed it without hassle. Did a very good job. I am now looking to have the shop replace a transmission on another truck.

Had a new engine put in my mustang. Runs like a top. Plus I like the warranty too. 3 year/100,000
