Does anybody know of an alternative to the HKS 4.11 final drive gear? My transmission is being built at shep right now, and I've been waiting since the 1st week of september for it (car has been on jackstands). Today I spoke to Trevor and he said the HKS gear is on back order and won't be here for another 3 weeks, so I won't get my trans for another month! I literally almost fell out of my chair! My car is my daily driver, which means I'm having a really hard time getting around, I'll probably go insane if I have to do it for another month!

I really want to build my trans only once, which is why I wanted the gear right now. And seeing as HKS is pulling out of the US I don't know if anyone else will source them. Does anyone have it in stock right now, or have a comparable alternative?

How proven is that gear? Does anybody have an experience with it in high HP applications?

 

Google and search the forum, it's been brought up a few times here.

 

Yea I don't see their "Pro" option for the Evo only the Road/Race piece which is rated for ~300whp (dunno why not ft/lbs either..) The Pro option says it's good for ~700whp. Unless I'm missing something. I'll have to hunt down the EvoM thread I guess.

 

I heard Mfactory stuff is pretty much junk except in maybe hondas. Like to see some proven stuff before buying it.

 

I'm not very encouraged by this Mfactory stuff. We all know the HKS gear is bulletproof, I'd want something of the same caliber that can be sourced in like a week. The best case scenario is someone actually has a 4.11 gear on their shelf or something. I'd pay $1300 right now for it.

 

Tokioma 4.0 Final drive as well. We are currently testing it in Luke's car. There will be a review and video shortly

 

As far and final drives go they are all pretty strong and you will have a gear failure far before a FD failure unless it's made of balsa wood.

 

mfactory is junk, dont waste your money.

 

They had a booth at MOD and i got to have a look at the final drive gear. Very nice looking peice and affordable. Tomioka Racing I beleive it is called.

 

Thanks...caught my SIC. Yes Tomioka. Apparently I shouldnt drink on the job

 

Tomioka.

you got to be kidding. you dont see a coincidence that they sell the same three ratios Mfactory makes?

 

Try giving TRE a shout. Maybe Jon has one on the shelf?
