Quaife ATB QDF3P in Gen.4 Jimny?

Hello Folks
I have a gen.2 Suzuki Gypsy into which I had installed the Quaife ATB QDF3P rear differential. I have now owned a gen.4 5-door Jimny since a few years now. I want to know if I can remove the same differential from my gen.2 Gypsy and plonk it  into the rear of the Jimny? The new Jimny has BLD and I do not know if a Torsen LSD can interfere with  an electronics controlled feature like BLD. Would it just be superfluous and useless or a safety risk? Assuming the new gen.4 has the same 26 splines axle of course (is it?)…

Thanks for your feedback on this.

I have no "Gypsy details" so I won't comment on the interchangeability aspect of the question, other tha to say, yes, it is my understanding that the Gen4 Jimny is a 26 spline.

There should be no issue running an LSD or a locker with the electronic BLD on a Gen 4, the mechanical function would/should reduce the need for BLD, in essence the electronics only comes into play when the system detects a difference in speed between the two wheels on the axle, it's reactive, if the LSD or the locker are working, they will reduce or eliminate any speed difference between the two wheels.

Thank you for your reply. I did some more research after I posted this question and it seems that a Torsen LSD will only result in lesser amounts of  BLD being applied and there should be no safety risk as such. 

FYI The Gyspy is nothing other than the gen.2 Suzuki Samurai that was manufactured in India until 2019. Sharing a Pic of my car for some eye candy… (couldn’t resist 😅)
 

 

Let me put it this way - about twenty years or so back, we had a medical doctor who decided he wanted to sell cars and started a dealership, he imported & sold, among other brands, a couple of different Maruti models, the Gypsy being one of them. The business didn't last long, and one of the challenges that the purchasers faced after it closed was sourcing spares. I would have been one of these unfortunate souls, if my wife hadn't nixed the purchase.

There are quite a few differences between the Gypsies and the Samurais, and for that matter, between the different versions of the Samurais, depending on the market they were built for.

A quick look at Suzuki's parts catalogs reveals that there are actually in excess of one hundred different models of the Samurai, Gypsies not included.

Yeah ok but this one has an existing supply chain in the country because the Armed forces and government bodies have 1000s of these still waiting to be phased out.
Edit : I am guessing the person simply didn’t have the right contacts to establish a proper supply chain back then… because an ecosystem of  OEM suppliers did exist back then.

The Quaife ATB LSD worked in the Gypsy because some of the core engineering parts specs have remained the same across all Jimny generations. I just saw that the QDF3P is also being sold for the gen.4 Jimny so it seems to be the same 26spline 10bolt setup… it’s just a matter of swapping it out of my old car and into my new Jimny. If anything is found incompatible the original diff goes back in to where it was ….

 

Yes it will fit and it will greatly enhance the effect of the traction control. The combination of traction control and a torque biasing diff is very effective. Essentially when the traction control system applies the brake to the faster wheel it gives the diff more torque to bias to the slower moving wheel.
