What is POSI?

[73GMC1500]

@norfolkdash9 also known as a limited-slip differential

[norfolkdash9]

@73GMC1500

Is it for the clutch?

[73GMC1500]

@norfolkdash9 No, if your rear wheel would spin (aka. when stuck in snow), both tires will spin with a posi, but on a normal differential, only one would spin

@73GMC1500

But don't most trucks have posi?

[73GMC1500]

@norfolkdash9 Yeah, but theres plenty that dont.

@1990fordf150custom

Ah that makes total sense! Thank you!

[1990fordf150custom]

@norfolkdash9 yea your rear end lasts a lot longer because when you turn one tire has to travel faster than the other,and if it posi the the tire gets worn out very quick and easy and it puts alot of stress on the rear end, if you only use it on the road then a limited slip is what you want, if you offroad then you want posi

@1990fordf150custom

Ah I see. But is there any positive effects for not having posi?

[1990fordf150custom]

@norfolkdash9 yea posi's get more common as the package goes up, like some 250's or 2500's have it and normally if its in 35 and up they go for posi because its better for towing and work
