KTA Cummins and transmission torque rating

A stock KTA 600 is rated at 1650. Tuned I have seen them produce up to 2000 easily.

 

Keep in mind that when the KT and KTA Cummins were the hot set setup a 125 transmission was the heavy duty ones. And they seemed to stay together, closed case no coolers

 

In the mid to late 90s many KT and 3408 engines were picked up on the west coast from CA to BC by a group of Aussies who shipped container loads to their operations down under where they built road train tractors.

 

Most western trucks in the late 80s and 90s running KT and 3408 engines ran 15 speeds or 5X4 or 6X4 transmission sets to run mountainous country.

 

Yes they were mostly in older trucks when I came across them in the late 80s when I started running the wet coast instead of the midwest.

 

Plenty of K series were sold here right up until the late 90's... in fact you can still buy a New Kenworth Fitted with one.

14613 too. Lots of big power back then was behind those 2. I like the feel of how they shift compared to the RTLO. Ours will run about 190 on a hot day.

 

The deep reduction on the low side. If i had a choice I'd take an 8LL over a 15
