Gear Ratio 3.909
Molybdenum disulfide (MoS2) coating applied
Comes with J’s Racing reinforced ring gear bolts (KRG-S1)
With the 6 gear ratios available from 3.9 to 5.1, a driver can find the best final gear ratio for his/her driving stage from the street, autocross, drag racing, short track racing to long track racing. By keeping the rev at the optimum range, the enhanced acceleration and the throttle response will definitely produce a better lapping time.
The molybdenum disulfide coating that is applied on the surface dramatically improves the durability, heat generation characteristics, and quietness. The set includes reinforced ring gear bolts (10 pieces) which enables tightening torque -11.0kg fm ( vs stock value of 7.6kg fm) and prevents differential gear related problems.
Molybdenum disulfide (MoS2) coating.
Molybdenum disulfide is the inorganic compound and has excellent lubricant characteristics. As a lubricant, it is far more effective than the popular graphite and is considered to be the best.
The molybdenum powder which is made from a specially blended compound produces a film on the surface of a gear and the film、working as a cushion between the pinion gear and the ring gear, is extremely helpful to prevent the initial wear and tear. It is also effective in reducing the gear noise.
The effectiveness of Molybdenum does not decline even in a face of very heavy load on the pinion and ring gear at a high rpm. Furthermore another advantage is its low coefficient of friction, which restrain the rise of oil temperature and the gear teeth wear.
The molybdenum coating can achieve the important but sometimes difficult goal - the maximum torque delivery at a high revolution with lowest possible friction.
The film thickness is 10 ~ 15 μ( micro ), which allow a slightly tighter value in the backlash adjustment to prevent the wobbling.
A set includes:
Pinion gear x1
Ring gear x1
Reinforced ring gear bolt x10
It is crucial to ensure to use the reinforced bolts and apply the tightening torque of 11.0kg-fm for optimum performance
J’s Racing recommends using our special differential distance collar (DDC-S1-100) for the perfect combination.
The installment is to be performed by an experienced mechanic at a properly equipped shop.
