okay im collecting parts to build my 78 bronco and it going to be built for mudding and it will have 44" boggers and I want to know what gears I should get and Im also not sure what type of lockers to use. I ws thinking air lockers front/rear or eletric front/rear thanks for the input.

depending on power id go 5.13 or 4.88.

02-23-2006, 04:53 PM
power will be via a 521 stroker around 650hp and 600ftlbs and a C6 and np205

lockers I would use the e lockers air to un reliable or weld the rear and e lock the front.gears I would use 5.56 or so and go with the high stall converter,say 3000 . I don't think I would put the 2nd gear low gear set in it though with that power it should work pretty good as is .

hey boyzen what do you mean 2nd gear low?? The trans has the ford racing wide ratio kit and a full manule revers patteren valve body in it already. and the fuel will be 112 octain when its on the bottle and pump when not

With the power you're talkin about runnin I would say that 5.13s would be a good ratio
DO NOT go air lockers ARBs suck to many air leakage problems and I am talking from experience I have serviced so many ARBs for seal problems
If it was mine I would go Detroit Locker rear (14 bolt chev is the cheapest to buy) they are bomb proof and many years proven
in the frt I myself am running the Detroit Electrac in my 60 and I like it some of the features are...
when not locked it is a posi (built from the Detroit True Trac)
if the electric motor screws up it locks up not unlocks like an ARB(they give you an emergency unlock spring and cover plate in the kit)
when it is locked it works like a manual locker ( ie Detroit Locker) not a spool or welded spiders like an ARB so you can actually turn corners when locked if you get off the throttle just like a Detroit Locker

thats my opinion it is what I run in my cj
14 bolt chev rear Detroit 4.56s an 35s
high pinion D60 frt Detroit electrac

I hope that helps

5.13's are as high as you can go with a 14bolt

Always broke

Well i run 4.88's and 44's in mine and it works just fine .5.13's will be way too low you won't get the most out of a big block 5.13's are more appropriate for a small block . as far as locker NEVER use air lockers they always fail when you need them mine is posi up front and welded in the back I plan on changing the front to the electrac they are amazing. i also run a c6 205 and a 429ci in a 78 bronco[36]

weld the rear and have another beer

02-23-2006, 11:09 PM
well I went and pulled the cover off of the 14 bolt and found out that it has a govlock and 4.10 gears. now what should I do??

02-23-2006, 11:35 PM
the detroit for the 14 bolt actually installs in the open case carrier similar to the Lokrites (but is a true detroit) if you want to run one you will need to find an open case carrier (that shouldn't be to hard they've made about a bazillion of those rear ends)

well I phoned randys ring and pinion and asked them if they make a spool for the FF 14bolt and they do so that will be on order soon aswell as the gears.
