What gears should I order?

[Firebird67dude]

Should I get Richmond 4.10s or Motive performance 4.10s? Tho motives are $189 and the richmonds are 191.

Any opinions?

[MonmouthCtyAntz]

Motive, Richmond are garbage and whine like a baby. Broke a brand new set on my old 97z.

Which ever the person doing your rear prefers.

Justin is tryinf to say(I think) Go with whatever brand the installer perfers.

[Blacdout96]

I think what he means is, if its goign into a 10 bolt, doesnt matter, its a weak rear. putting it under alot of stress ( i.e. drag radials, burnouts, excessive launches) expect them to go bad, and its not jsut the gears that go bad, but the whole unit tends to flex, and so do the caps that hold the housing in, and the axles....yeah same deal, weak, and not enough splines, so it doesnt matter what your putting in, the 10 bolts are 7.5 7.625 diameter, which is very small for our cars, and alot of stress is put on them to rotate them. although I do prefer Motive's myself.

Most installers will have a preference of what they like to work with. Pretty straightfoward.

[camaroAL]

either brand will be fine if setup correctly.

[wretched73]

summit brand.... its made from the same steel as the the companies you asked about...

[Firebird67dude]

Installer is my boss and myself so he realy couldn't care any less. I was asking to see if anyone knew any strong points of each.

Thanks I understood what he meant. Richmonds are junk, go on any fbody board. They break teeth and whine terribly. I and a ton of others have seen it first hand. Motive is definately the way to go. Maybe the installer doesnt normally work on fbodies, alot of shops dont but will still install gears.

Then just buy which ever ones you can get cheaper and call it a day.

Neither save your $$$$ for a REAL rear :nod:

[baddest434]

if richmond was buy 1 get 3 free then i'd say richmond! they do suck, very weak. personally i would not even take richmonds if they were free.

[camaroracer1992]

never had a problem with richmonds, running mid 10's on em for 4 yrs on the 5 years same set not a problem.

[Pampered-Z]

Motive gears. I'm running the 3:73s in my 10 bolt and the gears are about the only thing that hasn't broken!

[badzracing]

I have broken every brand gears out there except for stock chevy gears. My truck has an 8.6 10-bolt and weighs 4800lbs, so I may not be a good point of reference, but I was going 11's with slicks, driving it 70 miles a day, and towing my dad's impala once in a while with stock GM 4.10's and never had a problem with them. Richmond, yukon, and motive...broke all of them more than once.

[Bangin Bob]

let me know we are a dealer for motive. if your interested call me we will get you a price. thanks Bob

[NastyEllEssWon]

save for a 9''

I believe GM's gears are sourced from either Motive or US Gear.

That's interesting. Gear sets are luck of the draw it seems. I have never tried U.S. gears directly, but maybe that's what the "stock gm" ones are...

Yeah. With the ones you broke- did you do the recommended break-in? I would assume so, but some people don't.

WBT, if you have the break in procedure, can you post it on here ,and have it made a sticky, it would be very informative to any of us who change out our gears.

[WildBillyT]

I usually post up Randy Lyman's article:

I've done it 3 times and it's been good so far.

breaking in a set of new gears is very important to the longevity.

you will be surprised how hot a new gear set gets when they are

breaking in and that can alter the metal strength.

imo the best gears are the micropolished ones run on Nascar.

The work hardening process is pretty much key, and that's the step that people can F up if they don't break in gears.

[alamantia]

I broke 4.10's in on the drive down to raceway, about 40miles, they cooled off for about 10min before my first run. Quiet ever since.

i believe you are correct sir :mrgreen:
