RECOMMENDED SYNCHROS: When ordering your MFactory Close Ratio Gears, we highly recommend that you order our Carbon-Moly Synchros at the same time. By utilizing a carbon/molybdenum coating technology, which acts as braking material during gear engagement, this allows for quicker and more precise shifting. This also prolongs the life of your new synchronous gearset. Available for Honda B16A2/16B/18C, D15/16 & H22A in 3rd, 4th & 5th Gears. CLICK HERE for more information.

B-Series 5th Gear Shaft Brace


Help keep your high-horsepower transmission together with the MFactory Shaft Brace.

By keeping your transmissions shafts locked together (but still able to spin freely as intended), our Shaft Brace helps counteract the effects of Radial Loads created from highly loaded gears.

Our Shaft Brace is particularly recommended for those running straight-cut gears in their high horsepower transmission due to the increased Radial Loads created (an inherent weakness of straight-cut gears).

- Made from imported Japanese Steel
- Only the highest quality Japanese Bearings used
- Helps reduce shaft separation caused by Radial Loads
- A must for all high-horsepower drag cars

MSRP: $199.95 + Shipping

<---------- IMPORTANT NOTICE ---------->
We have recently become aware of cheap and inferior "copies" of our Final Drives & Close Ratio Gear Sets, including our own custom ratios, being made available on the market. These DO NOT go through the same forging and heat treatment processes and will compromise your safety if installed on your vehicle. STAY SAFE and only purchase your Final Drives & Close Ratio Gears Sets from an Authorized MFactory Dealer

Okay so maybe you could give me some advise. I am currently working on building up my 1993 Integra. I am keeping the stock power plant (B18A) and would like to keep my tranny (YS1). My suspension is fully built from a Full-Race traction bar, LCA's, coilovers, and all new bushings. My motor will built bored and sleeved and run at 9.8:1 CR. But this is far from a mild motor as all internals are being upgraded. Now here in lies my issue. I will be running NA for the first year or so untill I can afford a decent turbo kit. I know nothing when it comes to gearing. I would like to buy a set of gears that will work good for both appliications. Any advise?

 

If low boost, you would probably get away with using a similar setup to All Motor (e.g 4.785 or 4.928 Final Drive).

If high boost, then it would be a different path unfortunately.

 

I actualy plan on running around 16psi. I am hoping to see horse power in the 450-500 band.

 

What would be the different path?

 

With the higher power, you may need longer gearing, just depends on your overall setup and what is required.

 

can u pm with price for 4.9 final and first gear and lsd for 95 gsr trans

 

FD is $549.95 + $22 Shipping
Helical LSD is $649.95 + $30 Shipping
Metal Plate LSD is $899.95 + $30 Shipping

 

Was interested in long gear set similar to Integra non-gsr S80

 

The closest/longest we have is the 1.430 3rd and 1.100 4th gear.

 

pm`d

 

is the pro series 1st gear 2.786 straight cut (for b16) include both 1st gear on main and counter shaft to achieve that ratio? can it be bought separately?(ie. just the 1st gear coz my current 1st gear is 3.070 Mfactory)

 

It consists of straight cut 1st & 2nd, mainshaft & countershaft. You cannot use them with any other gear, they must be used together as a set.

 

bump!

 

H22A PRO Synchro Gear Sets now in stock!

 

Any idea when K-series road race gear-set will be available?

Have any 5.0ish final drives for a K20? selling any different geared 5th & 6th?

 

The K-Series gear set is still be tested at the moment, no eta yet.

Yes, we have a 5.08 FD available.

 

ok
what i need to my setup is
4.785 fd
or
close gear ratio
b20vtec fully build skunk2 pro with y21 tranny

 

I'd love to pick up the 5.4 FD to compliment my MF lsd

 

Thank you for your support

 

I yhave a question on the pro gear sets if I wanted to replace all my stock gears with them 1-4 what would it cost me, and what all is included in this set.

1994 gsr s80

 

Getting an error trying to PM you...

i have a b18c thats built for 600whp+ but i have it capped at 386whp due to a stock drivetrain. i dont want shorter gears since all it will do is spin, but i do want stronger gears and synchros. do you offer anything thats not a shorter gear? whats the difference between the metal plate lsd and helicoil?

i do street drive this.

thanks, doug

 

sanman000719: Price for the full pro synchro gear set is $2999.95 + shipping. This includes a new mainshaft, 1st, 2nd, 3rd and 4th.

EG6 Love: Our pro synchro gear set is not too short, so should be suitable for your needs. For drag/street, I would recommend the Helical as it is maintenance free and designed to handle your power level. The Metal Plate LSD is more for circuit use.

 

do you offer a complete kit for the synchro gearset? ie. 1-4 gears and mainshaft. carbon/moly synchros, lsd, bearings and final drive? if so please let me know. its for a drag car that will occasionally see street duty. i want to have a transmission that will stand up to 600hp-800hp safely. thanks

Mike
