and if you do want to regear, look for some 3.9's out of a 2014/2015 diesel auto. I put 4.1's into my diesel manual and they're great offroad, but tend to rev a bit much on the highway
if you ever do rebuild, make sure to get master install kits and solid spacers (helps them stand up to abuse better)

My Questions
- Am I correct in saying that moving either to 3.9s or 4.1s on 32s will only bring positive effects to the vehicle i.e. won't compromise longevity, better on-road manners, and better off-road performance?
- What is easier to source and what is cheaper? The 3.9s or the 4.1s? To me, it seems like the 4.1 is easier and cheaper (see shopping list below) whereas the 3.9 requires either genuine Toyota or wrecker scouring (for 2014+ HiLux D4D auto crown wheel and pinion).
- If I decide to go in with a rear ELocker only plus re-gear, will I still require a front Prado carrier? I see that Monster Rides can provide 4.1s to suit the standard HiLux carrier. So, I could theoretically go 4.1s front and rear, rear Elocker, and save on the cost of the Prado carrier as the 4.1s suit the standard carrier?
- If I follow through on the previous scenario, will I have any issues fitting a front ELocker down the line (due to now having thick-cut 4.1s in the standard HiLux carrier)?
- If I follow the scenario in 3) but with 3.9s, I will require a Prado carrier. Correct?
- I saw in a previous post that a power increase led to rear diff damage. I may chase a mild power increase in future; should I be concerned about damage to a 3.9/4.1 after a small increase in power?

apSlain wrote:The Shopping List
Alright, so let's say I moved ahead with all this. Is this absolutely everything I'd need to get the job done (for this list, assume 4.1s were chosen)?
- HARROP Eaton ELocker, Front - 99-ELKR11110 - "Vehicle Applications: Toyota Hilux, 2005 - Current, front with 3.91 & Up ratios"
- HARROP Eaton ELocker, Rear - 99-ELKR9334-00 - "Vehicle Applications: Toyota Hilux, 1990 - Current, Rear"
- Nitro Gear 4.1, Front - T8S-410RT-NG
- Nitro Gear 4.1, Rear - TV6-411-29-NG
- HD Master Install Kit, Rear - MKTV6-29
- HD Diff Rebuild Kit, Front - MKT8-CS
- Differential Oils

From my (admittedly uneducated) view, 3.9s suit my configuration more (daily driver, 45m drive to work with half of that being at 100km/h and above) but seem to be more difficult to source, more expensive, and require an extra cost (front Prado carrier)? Whereas 4.1s seem easier to source, don't require the Prado carrier, and require less work now that they're readily available.
I think I know what I need, just need some confirmation from more savvy minds Cheers for anyone who can advise!

Only extras are Master install kit and Solid pinion spacers. Definitely recommended
imo 4.1's only suit 285 or bigger tyre
fwiw, that front locker does not match those gears. The gears are thick cut, so a standard Hilux locker for 3.5 ratio will fit

The Diff gears you need will be listed on the site linked to above but I'd recommend you call 07 3133 1660 and talk through what you want rather than just ordering the parts blindly as Nitro have a couple more options now becasue they offer both 27 and 29 spline variants of the 4.1 diff so it is no longer necessary to order the Drive flange which was required.
apSlain wrote:Yikes, knew I'd get something wrong. So 99-ELKR10994 - "Vehicle Applications: Toyota Hilux, 2005 - Current, front with 3.73 & Down ratios" will suit here due to thick-cut 4.1s (if I decide to go the 4.1 route)? For 3.9s, go the 99-ELKR11110?
Could you clarify what affect the 27/29 spline variants of the 4.1s will have on completing this? I skimmed over the spline count completely. From my quick research just then, we previously needed a multi-fit drive flange to get everything to mate. However, I'm assuming the increased options offered by Nitro make this no longer necessary and it should fit out-of-the-box (assuming the correct gear is purchased)? Are you able to clarify on what spline count I'm after for front and rear re-gearing on an '06 SR D4D, manual transmission?
