Diff Ratios

[ENYXR]

Wanting to get the ratios changed on my diff, I've spoken to a couple workshops and they're wanting $500+
but after speaking to who I'm buying the gears off they've said that's a huge amount to pay especially if it's just a ratio swap..
He's over-east though so there could be a difference in pricing, I didn't think it would be that big though, according to him it should only be around the $200 mark

Does anyone have any info/recommendations on this?

Gearset new or used?

Do the quotes include bearings?

[dattoman]

What sort of diff ?

I used to work for a company that sold diff gears... $500 would not buy many let alone the labour to fit

Dalspec FTW !

With diff's setups I've really found generally you do get what you pay for.

Having seen how much time Dally puts into a well setup diff I actually think its very reasonable to spend decent $$.

Definitely agree with this. Having gone through a few different diff setups on different cars, I can safely say that you definitely get what you pay for.
Take the cheap option and there's a chance that you'll get something sloppy, whiny and has a crap load of back lash. I found this out the hard way unfortunately :/

The gears are used and out of a hilux, going into a torsen LSD in my Chaser.
I was hoping to get away without changing the bearings and whatnot but if I need to I will, it'll just have to go on the not-important list for now.

Thanks for the mention lads, appreciated.

ENYXR - you do need to replace the bearings. It's not worth messing around with the old ones. Generally a combination of old and new is used to determine pinion height. This typically involves machining one of the races so it's a light interference fit - ideal for pulling in and out whilst height is set. Once the height is established, the balance of new bearing parts is installed.

Some companies install new bearings and use the donor diff's pinion height spacer. This is the cheapest and fastest way to do it but is not recommended.

Pinion bearing sets are typically in the range of $150-250. This goes some way to explain the $500+ quoted.

Hope it helps.

Thanks for all the info guys!
I'll definitely get in touch with Dalspec when the time comes to replace the gears in my diff.
