Juggernaut 1000HP - Allison 1000 Transmission | Built By Inglewood Transmission


There is a reason this transmission is called the Juggernaut. It is the Allison of all Allisons. It does not get any better PERIOD!!! This transmission was the first to the 5's in the 1/8 mile and first to 8's in the 1/4 mile and countless low 6-second 1/8 and 9-second 1/4 mile passes in multiple different trucks over the years. It still holds the fastest 1/8 mile and 1/4 mile Allison records. This isn't a one-hit wonder like many others out there. Our proven combination is repeatable, and we've proved it is time and time again. If you want the end all be all of Allisons, look no further than the Juggernaut is it.
