Introducing your ultimate choice for a top notch direct-fitment replacement in your B-Series AWD racecar - The Albins x SpeedFactory B-Series AWD Extreme Duty Final Drive set!

Combined CAD engineering, failure analysis of OEM & other aftermarket final drives, and years of torture testing and proving out numerous FD set designs in our Outlaw car has resulted in this set which was designed for maximum strength.

We’ve added tooth width and support while retaining the OEM needle bearing sizing on the pinion shaft combined with a low helix design that shares loads among multiple teeth simultaneously. This offers high strength and copes with shaft and case deflection/distortion better than similar straight-cut designs. Tooth count is optimized for maximum strength.

This set is a direct-fit replacement and is compatible with OEM gearsets and aftermarket factory layout gearsets.

Gear Ratio Notes: After countless hours were spent running gearing comps for common combinations, this ratio was decided upon to best suit the majority of street/strip and purpose-built drag cars that are making serious HP and need an upgraded final drive set. Serious street cars on 58-67mm turbos at 600-1000whp as well as 1100-1300hp drag cars will all work great with this ratio.

  • Ideal for serious 1100-1300hp drag cars utilizing this Albins 4.09 FD set with the proven Albins 1-4 B Dog set & our FWD2AWD Gear Conversion Kit. Perfect for mid 7 second ET’s and 170-190mph trap speeds at 10k-11k rev limits on 24.5” slicks.
  • 600-1000whp street/strip cars on 58-67mm turbos utilizing this Albins FD set with an Albins 1-4 B Synchro set & our FWD2AWD Gear Conversion Kit will find that this gearing works great whether from a dig or in typical 30/50mph start roll races as you will be sitting at 5300-5800rpm in VTEC where the turbo can be loaded and spool hard right from the hit. You will be able to run 150-170mph trap speeds at the normal 9k-9.8k rev limits on typical 23-24.5” diameter tires.

Product Specifications:

  • Low Helix 4.09:1 Ratio
  • Can be used with Albins Synchro or Dog set and our SFR Conversion Kit, or as standard replacement
  • Manufactured to ISO 9001/2000 quality standards
  • Billet high-alloy proprietary grade steel
  • CAD engineered custom tooth profiles

Save some money by doing your own cabin filter change! (You won't notice a difference).
So, one day I was getting an oil change at the dealership, and the associate told me that cabin filter was pretty dirty, which I believed because of the places I take the car, and she said that they could change it while they were finishing up the rest of their inspection, since they already had it apart. I asked her "How much?", and then we both had a laugh when she said "$90." I told her I'd take care of it. It took two days for Amazon to get a replacement filter to me, twenty minutes to watch a You Tube video showing how to replace the cabin filter on my car (I watched it twice), and then about twenty-five minutes to replace the filter itself--I keep a messy glove compartment, so a good portion of the time was loading and unloading that nightmare. In the end, under $15 for the filter, maybe 45 minutes to watch and replace, and the cabin filter hasn't been this good since I first bought the car. This replacement version was as good as the OE filter, fit exactly the same, there's no difference in airflow that I can tell, and so far (6 months later), it seems to be holding up pretty well. We'll see what it is like after a year. I did get the oil changed about a week ago, and the technician didn't raise any alarms about the filter, so everything seems to be working. $90 for a new filter? You can do it yourself cheaper.

Fresh Air Upgrade for My 2024 Impreza
Installed this in my 2024 Subaru Impreza, and it fit perfectly—no issues. The air smells noticeably cleaner now, and it took less than 10 minutes to swap out. The carbon and HEPA filtration does a great job clearing out odors, dust, and pollen—definitely an upgrade over the factory filter. The build feels sturdier than the OEM version, though it does have slightly fewer pleats. Might mean it needs replacing a bit sooner, but for the price and performance, I’m fine with that tradeoff. If you’re looking for a quick, affordable way to improve your cabin air, this one’s a solid pick.

Well built, good fit.
I like it so well, I just bought two more to keep on the shelf for when the price doubles. Seems better built than oem, but I don't know how you can judge the filtration; seems good though.

Good Product
Size: (Pack of 1)
Came with all necessary supplies. Seemed to be of good quality and my taco is running well after the oil change. Will buy again.
