they are the same ratiao as stock na 5 speed, auto, and tt 6 speed.

 

you mean whatever they are replacing right? as each NA 5sp auto and tt have different ratios

 

yes whatever they are replacing. auto for auto, na 5sp for na 5sp, 6sp for 6sp. only way to get different gear raito's in the rear diff is powerhouses 3.27:1 custom rear diff ratio gear set or jdm supra rear diff gear set. i think jdm supra's were 3.17:1 but im not 100% sure. edit:jdm gears are 3.27 as well.

 

what are US ones? i have a JDM 5sp NA with LSD

 

AN LSD has no ratio. The ratio comes from the gear set you bolt to it.

The 6 speed has a unique differential while the NA and TT AUTO are interchangeable diffs but different ratio (4.09 vs 3.76)

-M

 

yes but the trd comes with the gears inside of it already. so he is asking what ratio comes with the trd lsd. if you search the boards you can find the rear diff ratios. its 4am over here i still have some studying to do or i would search for you.

 

no it does not come with gears. Yes, the LSD has gears in it. So does any differential.... that's what makes it a differential. The ratio comes from the ring and pinion, and they are not included. BTW, the differential, from TRD is about $800, the stock unit is about the same IIRC, but the ring and pinion are around $800 as well...... and they get replaced in sets, not a ring seperate from a pinion.....

 

YOu can buy the LSD for Auto or Manual.
