We have been working hand in hand with Jasper Engines & Transmissions for decades. No matter how good your work is or the parts you use, at some time you will run into needing a warranty repair. Jasper goes above and beyond, starting with tackling common problems with each different engine and making updates we wish the manufacturers would make. This eliminates the common problems from recurring. In addition to help prevent something else causing a breakdown or damage to the Reman Jasper Engine, they supply an Install Kit which normally consist of Spark Plugs, Ignition Wires, Thermostat, Water Pump, Belts, Hoses etc. In the past 3 decades of using Jasper, we've had less than a handful of problems and all were stood behind and taken care of.
