Put it in 4th and hammer down, you'll find out!
It depends on your tire size, gear ratio, motor mods, GSK or not, uphill/downhill, wind, etc.etc.

mine topped out @ 120kph sometimes i could get it to 135kph...

how fast will they go in 5th anyway ??? i'm unable to push mine past 165kph :P

anyone want to take a guess at my ratio ??

Order code says it has 3.64 or something similar, i'm thinking they're 4.10s !

i do around 75 or 80 layed out on the floor in 5th, maybe i could get 55mph outa 4th. apparently my truck is the slowest Cummins around, nobody can figure it out, it drives like a dream, just feels like it has taller gears then what it really has...
