hey guys , just wondering how much reduction do ya get with the 1 ltr transfer in a 1.3 ltr sierra any info would be muchly appreciated .

[jdk81]

12% roughly high and low
1.0l high 1.578, low 2.511

1.3 high 1.409, low 2.268

[yareckonillgetupthat]

that doesn't seem like much ? ya think its worth doing ?

[jdk81]

What size tyres are you running?

Its not much.
Aftermarket gears offer more, but cost more.
When needing some reduction and for the right price a 1.0 case is way better than no reduction.

31's, yea true, theres one for sale for 100 bucks near my house ,ad says non switched what does that mean ?

[jdk81]

Non switched is often worthless.
You need 1.0l flange yokes, so you can bastardise your driveshafts by mixing unis with 1.0l unis.
Most people dont bother

yea ok, i thought i could use the flanges of my 1.3 t case so its harder than i thought
