BOTH trucks have 4.10 geared axels...BOTH were non-overdrive automatics....both are the same trucks except one has a chevy name slapped on it and the other GMC.
Both Full size 4-wheel drive long beds regular cab..
the 5.7 liter Chevy V-8 gasser has far more engine braking than a larger 6.2 liter diesel in what is effectively identical trucks.
And also if the gassers have less engine braking argument was true why are engine brakes not made for gassers....just for diesels? lots of gasser trucks, lots more than diesels.
