These are our American-made billet gear reduction offerings for the 85'-87' Honda Foreman 350D. Our gears are CNC machined from raw billet 4140 material, not powdered metal like the cheaper chinese brands. We designed our own proprietary sizes of 20% 40% and 60% reduction specifically for the 350D Foreman. Gear indicator cup delete/neutral wire mod required. We offer stiffer clutch springs for these reductions which can be found in the "Foreman 350D" and "Parts" sections of the site listed as "TRX Springs". The stiffer springs can be ran with any size reduction but are necessary for the 60% to prevent clutch slippage. There is a sizing chart tab on the home page with reduction to tire size recommendations.

We have an install video on YouTube for the TRX300 which is very similar to the 350D. The main difference is the 350D does not require grinding in the kick stopper area.

Excellent fit and value - recommended buy
Size: 3+12+12+2+1 pack
I rarely write reviews, but I'm so impressed by the fit and quality of this set that I made an exception. I'd been running my eufy 11S without brushes, and have been cleaning and reusing the filters for a while now and finally decided to buy replacements. The kit came packed well with everything in order and no damage. I replaced all of the worn parts and installed the brushes and did a test run - everything worked great. I expected some fitment issues because I've seen that with other kits, but I had no issues. The fact that you get multiples of almost everything is icing on the cake. Oh, and I wasn't paid or given anything in exchange for this review, as much as that's worth now, haha. I can recommend getting this kit for your robot vacuum, if it's the right set for your model.

Good option for an aftermarket replacement solution.
Size: 3+12+12+2+1 pack
I've been very happy with this product. I think it is a good price point for what is included. Everything was a directly compatible and everything fit as you would expect. The filter quality is good and since there are plenty in the kit I find I change the filters more often which is probably a good thing. I recommed.

Eufy Brushes wear out with daily use
Size: 4 Pack
These brushes help the Eufy continue to run efficiently. I have 2 dogs and run 2 Eufies daily. It is surprising how much sand, dust, gravel and hair gets vacuumed. My furniture isn't as dusty and my floor doesn't need mopping as often.
