OBX Limited Slip Differential Review
OBX helical gear limited slip diff provides you with a smooth and silent operation with greater traction. An auto torque biasing system resists the excess power that is allocated to a single wheel. Installing it means you achieve tight cornering for circuit racing.
From drifting to cornering, this unit will make all things precise and perfect. The accurate size ring gear fits smoothly and accurately. However, the product is built to last which ensures durability and a long-term use guarantee. So if you want a high-quality and long-lasting diff for the best traction, pick it for now.
The Features
The OBX helical gear clutchless LSD is packed with some tremendous features and has great value. Look at its exceptional yet significant features before buying it for your vehicle.
Smooth Function
This OX helical gear limited slip functions like a standard limited slip. It operates with both worm and spur gears that eliminate the need for clutches or any other wearable parts. What does it mean? It means you don’t need to worry about wear and tear. The spur gears differential comes with the same-sized gear for each half-shaft but has standard space between them to operate quickly and right. The gear ratio is also perfect to adjust the rotational angle correctly.
Helical Gear Design
There are 12 helical gears and 6 for each side. This traction system features a helical gear design to ensure better handling, stability, and control for daily commuters, off-road enthusiasts, and heavy-duty truckers. Helical gear design has greater teeth strength and extreme load-bearing capacity. That means you are good to go with hard trails rough terrains or mud.
Helical gear can transmit the power of both parallel and crossed shafts which is mind-blowing. The teeth of this unit are set at the exact angle to the gear axis to engage more often. It offers tremendous, smoother, and quieter operation than other typical limited slip diffs.
Torque-Sensing Differential Design
There is another susceptible feature is torque-sensing benefits. That means when one wheel gets enough traction but others don’t, it will bias the torque to another wheel to get the most traction. So it’s now lots of fun to drive the harshest terrain or mud by achieving the traction goal.
The original OBX-R is highly classic and high-performing turning technology to deliver optimal acceleration and cornering. In addition, you can achieve better traction and handling than another differential right there.
Most factory differentials lose their individuality and power when the wheel spins under heavy acceleration. The OBX outperforms this and overcomes many disadvantages that other differentials make. It provides maximum torque to both wheels for an early start. As a result, it can handle bulk loads without making you bored.
High-Quality Materials
No matter which locker or differential you choose, all are the same when it comes to manufacturing and building materials. The OBX uses 9 8.8 robust and 2 quality M8 bolts to hold and keep the case firmly. It uses a 2-piece case with 11 bolts. The gear that OBX uses is floating inside the housing. It can be centered by the loose-fitting axle.
However, the unit is made from high-quality steel with a superb finish. It ensures ultimate durability and long-term user experience.
No Clutches
Most importantly, the OBX has no clutches to wear and tear out quickly. It uses either a cone or a plate that is used as an alternative to the clutch. Usually, there are double cones that are placed as a replacement for the clutch, but the function is the same.
The cones are pressurized tightly to achieve the same output as the clutch. In this type of part, frusto-conical clutches are forced into a mated machined surface located in the differential case by the spider gears. The cone-type LSD has a simple and easy-to-know design that everyone understands easily.
Again, the preloaded springs and side gears pressurize the cone into the dished depression. After that, this unit locks up the cone and side gear to the differential case, allowing it to perform better.
Easy Installation Process
The installation process is easy and less time-consuming. Though the function is slightly difficult to understand, the professional can handle it with a safe hand. So if you find the installation slightly overwhelming, leave it for a professional.
The Advantages
The following are some advantages of this unit you are looking for.
Lower Maintenance
This unit requires lower maintenance and most of the time no maintenance is required. It has no recommended oil to use and maintain every weekend or week that clutch-type differential demand. Also, it has torque-sensing biases to operate smoothly and responsively.
Lower Noise
It is efficient to perform cornering with the greatest traction and acceleration. Many other typical differentials can do cornering but produce harsh vibrations and noises. Fortunately, OBX LSD surpasses this issue and gives a quiet operation.
Reliable
OBX Racing Sports is a brand with better quality and quantity. This uni comes with a reliable and satisfying warranty package. There is a 1-year lifetime limited warranty from manufacturer faults. Therefore, you are good to go with this if you want reliability. The OBX is a reputed brand known for its cheapest product.
Improved Vehicle Traction And Handle
The unit gives the freedom to drive your car with proper and better traction. It has torque biasing benefits that help to gain enough torque for both wheels for greater traction. Also, it provides enough power and torque for a quick start.
The Disadvantages
There is a tendency for the cast iron of this unit to be porous due to residual cutting oil soaking into the pores. Besides, there are not so many limitations in this unit.
Final Verdict
OBX limited slip differential by OBX Racing Sports is highly recommended for AWD (all-wheel driver) vehicles, including Nissan and Mazda. The best thing that matters a lot is the teeth. OBX has longer teeth than Qualife. Also, it comes with 8 washer stacks. Interestingly, this unit uses a different spacer to mount or house retainers and washers.
The quality, quantity, built materials, and other objects are high-quality and satisfactory. Another thing you should note is its machined finish. Anyway, if you really want a high-performing, best quality, and toughest differential without breaking the bank, choose the OBX helical gear LSD. Read the OBX limited slip differential review carefully to know more.
