This is the latest in differential technology for the 1/28 scale.Unlike conventional adjustable ball bearing differentials, this differential utilizes a thrust bearing to control axial loads.This makes the distribution of power to each wheel more precise, providing a smoother throttle feel and a more consistent driving experience.
MC3WLS Manual Differential.
Features:- High Quality Thrust bearing made in Japan- ABEC 5 radial bearings- Silicon Nitride Ceramic Grade 5 balls- no more e-clip required! this differential uses a special threaded nut. This allows you to keep the same settings you had before cleaning/taking apart the differential unlike traditional ball diffs which will require losing your setting- comes with a set of precision injected molded Delrin 64 pitch gears and pinions- 52, 53, 54 Tooth Spurs- 9, 10, 11, 12 Tooth Pinions- titanium coated D-cut washers (compatible with PN Racing differentials)- 304 stainless steel precision cut shaft- T7075 anodized aluminum parts
For any wide width 2WD 1/28 chassisCompatible with Kyosho MR-03, GL Racing GLR/GT, Atomic MRZ

Frequently Asked Questions (FAQ)Q1. Why is this differential design special over other differentials on the market?A1. This design features two types of ball bearings: a thrust bearing controls axialloads while the spur gear and outer diff half bearings control centrifugal loads.This combination allows more precise transfer of power which means morethrottle control providing a more consistent driving experience.
Q2. Your diff seems expensive, why?A2. The differential is priced very competitively compared to other diffs on themarket considering it already comes with many upgraded components which arenormally extra for other companies. We include ceramic balls, titanium coateddiff washers, a 3 pack of spurs and 5 pinions along with a high quality Japanesemade thrust bearing.
Q3. Why did you put a stainless stain shaft in the kit? Isn’t that heavy?A3. The shaft is meant to be strong so we chose stainless steel. Although you canuse the diff for a stock class, it was meant for mod class. We will offer alightweight version of the diff in the near future.
Q4. Will it fit narrow bodies?A4. No, it is meant for wide bodies only. We’ve done this since we are solelyfocused on the best performance possible and that means racers will use widebodies as they provide the most cornering grip.
Q5. Will it fit into my LM motor mount?A5. No, it is meant to fit into a standard MM (mid mount) motor mount.
Q6. Does the spur gear use a bearing?A6. Yes, it comes with a bearing.
Q7. Does the diff use 3mm wheel bearings on each side?A7. No, it uses a 3mm bearing on the gear side and a 2mm bearing on the nondriveside. This way it will be compatible with those racers already using our quickchange wheel nut.
Q8. Should I use grease in the ball diff?A8. No, we recommend to run it dry. Running grease attracts a lot of debris whichwill negatively affect your performance. Even though it is run dry, you still need toclean the diff, just not as frequently. Please continue to clean and oil yourbearings using quality bearing oil not grease.
Q9. Why did we choose red for our gears?A9. It looks cool. Seriously though we choose red as it’s easier to see rubber fromthe track since it will show up more clearly to make sure cleaning was donethoroughly. Red is also one of our company logo colours.
Q10. What kind of grease should I use for the thrust bearing?A10. Typical bearing oil not grease. In particular, we have found Atomic thrustbearing grease will gum up and prevent the thrust bearing from working properlyso don’t use that one for sure.
Q11. How tight should the diff right wheel nut be?A11. Hand tighten is not enough. You need to use pliers but make sure not toovertighten. Holding just the shaft just to tighten may not be enough, we suggestto install the Diff left hub first to get some leverage to tighten the right wheel nut.
Q12. What assembly tips do you have?A12. Check out our instruction manual as it’s full of tips (Page 9)
Q13. What size rims can I run with this diff?A13. The diff is 2mm wider on each side when compared to a standard Mini-Zdifferential. This means using a +1mm wide offset rim is equal to a +3mm offsetwide rim on a standard Mini-Z differential. So do the math to figure out what youcan use for the body you are running.
Q14. Why is there no e-clip?A14. We’ve eliminated the necessity of using a e-clip to hold the diff together. Wehave replaced it with what we call the diff right wheel nut. This innovation allowsyou to keep the diff setting you had before when taking the diff apart forcleaning. The diff right wheel nut also assists in not overtightening the actual(outside) wheel nut that holds the wheel unto the diff hub. Most racerstraditionally overtighten this nut creating binding.
