"......but you were right AGAIN!!! 4:10's "
I know..., I hate it when that happens........ :lol:
My rig came to me with the 456's. The orig. 411's were in a box in the back.
The 456's keep the power curve happy in all three gears.
RPM's are a bit high on the freeway but these straight 6's can take a lot of RPM's (7 main bearings as I recall.)
Although, the Revs aren't much higher than 411's due to the 32's on the ground.
My other Broncos had various tire sizes with the 411's & they were V/8's.
I never felt lacking for power, no lugging, etc.
Short answer is.., YES I like the 456's. This rig is as fast or faster than the 5 other rigs.
I climb hills in second gear & don't dare give full power.
Lots of fun hi-speed trailing. I can run 3rd gear lo range & it's like a one gear automatic meaning
I don't have to shift down in slow spots. (I could go on-n-on..!)
However, I wouldn't advise to switch out from 411's unless tires were bigger than 32's.
I would say B/4 changing, try to find another Bronco with 456's that you could ride in & drive
a bit to feel the difference.
The ring & pinions aren't that expensive but the "tuning of the gears" is a bit tricky.
That could be expensive if you had someone else set the gears & do all the R&R.
Hope this helps..,
