SpeedFactory Racing Billet FWD2AWD Gear Conversion Kit - B-Series

FREE SHIPPING

Usually ships in 1-2 Weeks

The SpeedFactory Racing FWD2AWD B-Series Gear Conversion Kit has been created to provide you with the parts and modifications needed to easily retrofit a stock layout FWD B-Series gear set into your B AWD transmission with NO MACHINE WORK required!

Detailed instructions are included, and we recommend checking out SpeedFactory's FWD2AWD YouTube Video for an in-depth install with component explanations.

Why would you want to do this?

• The B AWD factory ratios were designed for a heavy SUV with a low 6.3k-6.7k rpm rev limit and feature a super short 1^st gear which does not work well with high revving high performance applications and creates major shifting difficulties due to the huge ratio spread on the 1/2 shift.
  
  
• The stock B AWD 1/2 shift forks are very thin and weak, often bending even in stock transmissions and are too thin for use with a FWD 1/2 slider.
  
  
• B AWD specific gear set options are very limited and retrofitting other oem gears used to require tedious machine work and custom spacer machining.

This kit now eliminates any need for machine work and opens your ratio options up to use almost any existing B-Series FWD gear set (either synchro or dog engagement that uses a factory style layout) and at the same time fixes the weak 1/2 shift fork issue by replacing it with a brand new replacement billet shift fork! 

Included Components/Services:

1. New Billet FWD2AWD 1/2 Shift Fork

2. Custom SFR 1^st Idler Gear Split Needle Bearing - Previously if you wanted to attempt this conversion you had to machine the ID of the 1^st gear larger or machine the countershaft journal height larger. With this custom bearing no machining is necessary!

3. Custom SFR Precision Spacers – Needed to achieve proper component locations

1. Mainshaft Spacer (replaces the oem flat washer under the mainshaft - retain the flex washer underneath and set endplay to factory specs)
2. 1/2 Hub Spacer (goes under the 1/2 slider hub)
   
3. Reverse Thrust Washer (goes under the reverse idler gear if you are using a short 41.9mm tall FWD 3.0 ratio idler gear. If you have a 45.8mm tall FWD or AWD 3.0 ratio reverse idler gear you do not need to use this washer)
4. Upper Cuff Shim (For use with Albins B Dog Set only, not used for synchro sets)

NOTE: You will need to use the gears, hubs, sliders, and synchros from the FWD sets and the pinion shaft and ring gear will still need to be an AWD specific set – either OEM or OEM compatible aftermarket final drive set. (Note: The B AWD 2^nd synchro & 3^rd/4^th hub/slider/synchros can also be used.)
