  .: Word from the Industry :.

"Being an engine builder and developer, we obviously want our equipment to work to the optimum on the track. The Merge ALJ enables us to make our jetting perfect and precise for any conditions on any given day in almost no time. And as in everything, especially Racing, time is of the Essence. So thanks to Merge Racing Technologies we have the last key to perfection. Thanks once again for the continued support! (Where have you been all our 4 stroke life!)"
