Have you noticed poor power and torque to the wheel and inconvenient wheel spin? Well, it’s a telltale sign that you have the wrong differential. In this circumstance, positive traction or positraction gives you real benefits. Like them, the JEGS 30-spline positraction differential is a highly recommended differential for your GM truck and other heavy-duty applications.
It has a ring gear located in the axles. It surrounds the gear train of the diff to serve equal torque between both wheels to turn faster without hampering the speed of another wheel. Also, the variable gear ratio allows the unit to alter the performance from worst to best.
However, there are lots of discussions going for this posi-trac differential. This JEGS positraction differential review will cover the features that make the unit more unique and demanding.
Highlighted Features:
- Differential Type: Posi-Trac Differential
- Built Materials: 4320 Chromoly Steel
- Item weight: 22 Pounds
| The Pros | The Cons |
|---|---|
| 100% rebuildable. Numerically higher gear ratio. Extremely durable construction. Reliable and affordable. | Even power is only distributed during acceleration, not always. |
JEGS Positraction Differential Review
The Jegs 62832 30-spline-based rear axles, entirely new positive traction for your GM heavy-duty truck, Chevrolet with the 12-bolt ring gear. This unit is a fully rebuildable unit with ultimate composite clutches. Another common yet must-have feature is clutch style availability.
Since the differential aims to provide greater traction in the harshest terrain, mud, snowy, or icy conditions, the Jegs’s limited-slip differential does exactly what you need. It meets or exceeds your damned while not considering the aggressive performance.
However, if you want to enjoy blissful, safe, and hazard-free driving no matter where you are, this positraction unit will cover it. Before buying make sure you know everything about the differential to avoid future hassle. Also, check the warranty policy and other important disclaimers provided by the manufacturer.
The Features:
Till now, we know the features and other important notes with a bird’s eye view. Now, in this section, we are going to disclose the exceptional yet workable features that blow your mind. Note that, this unit is a fantastic option for having standard-sized ring gear. Let’s explore more features and benefits.
Differential case Structure
Like other high-quality and high-performing differentials, this limited slip differential comes with a differential case to set in the rear or front side of the axles. The motto of using the differential case is to transfer more torque to the wheels faster and evenly.
Also, it helps to keep the RPM standard to make the wheel spin smoothly and at different speeds when required. In addition, when the wheel spins roughly and locks suddenly, it limits the steering to keep things safer. The differential case sits in the drive train to keep the balance wheel rotation at great speeds.
As we all know, a drive train is a component that includes transmission, axles., CV joints, differential, and wheels. So do you understand how important the differential case is to have a differential? Indeed, without this design, the wheels will be locked to a single axle.
Higher Gear Ratio
The gear ratio is important. And if it’s claimed higher, then the performance will amaze you. However, the JEGS LSD comes with a 3.73 numerically higher gear ratio. That means you don’t need to worry about traction or acceleration. With better acceleration, the driving will be faster and more speedy with less friction encountered.
Better acceleration means better driving controls. Also, it requires crash avoidance. In the drag racing world, the JEGS differential is efficient in handling extreme situations with its higher gear ratio. Most importantly, a higher gear ratio unit saves fuel economy if you drive your car at a slow speed.
State-of-the-art technology
This unit is designed with state-of-the-art technological advancement to ensure quality, durability, and testing. High-quality materials, advanced technology, and new dimensions make it a superb positraction system for your drive system. The unit is made with rigid and robust 432 Chrome-finished steel spider gear for unrivaled durability. The special JEGS yellow spring is also durable and functions incredibly well for a long.
4-springs Pack
The unique JEGS yellow 4-pack springs preload the axle gears under specific conditions to keep the axles rotating right. Under light throttle pressure, the springs snap and pop to receive better cornering. The 4-spring packs also help the clutch packs not to bind as they require additives.
Also, it will be easier to perform in icy or snowy conditions with the pre-loaded springs. The other task performed by the springs is to load the spider gears to rotate around the differential side gears.
30-spline C-clip
The more the spline number, the more torque will be transferred. Let’s make things clear. The splines are located on the shaft. They mesh with the mating part and transfer torque. This incredible number of splines makes it possible to perform drag racing using a 3.0625” bore case.
The number of teeth or grooves on the middle shaft is determined by the exact spline. This way, the maximum torque is converted to mate the transmission properly.
The Advantages
The following are some significant advantages of this unit to make you happy.
More efficient Traction under acceleration
In most cases, you can’t get good traction when accelerating hard. But the JEGS positraction will give you this benefit no matter what. It’s a positraction unit that is perfect to provide sufficient torque to both wheels. So there is no issue in spinning wheels roughly.
When you are in normal driving mode, the positraction LSD preloads automatically, which in turn provides equivalent traction to both wheels to give you smooth driving on snowy, icy, difficult terrain, and mud surfaces.
Made in the USA
The product is fully assembled in the USA. USA-made product is always top-rated and trustworthy no doubt about it. This unit has been tested perfectly to ensure quality and rigidness.
100% Rebuildable
Like the Yukon’s differential, Jegs produced differentials with 100% rebuilt scope. That means you are always in excellent mode. Why? Because there is no hassle in replacing the whole item. When any parts like springs, spider gears, and other internal parts get damaged, you are eligible to change only the worn-out part instead of the whole.
The Disadvantages
It has a 3.73 or numerically higher gear ratio which isn’t good for every situation. It is only good when you need more acceleration. Otherwise, it can’t serve you better than worse. Often, you find it a hassle to install it yourself. Therefore, you should hire a professional to handle this which costs you a little extra.
Conclusion
JEGS positraction differential works by connecting the differential’s sides along with clutch packs. It comes in handy when a single wheel begins to spin. In this situation, it distributes power to both wheels. In addition, a Posi-Trac differential means you achieve better grip because it allows the wheels to rotate at the same speed no matter whether you are on mud or a local street.
In a GM heavy-duty truck, it fits superbly to take you to extreme drive conditions. Another great advantage is it diverts poor driving by providing a better cornering experience at higher speeds or windy road conditions. However, if you want a high-quality positraction differential, choosing the JEGS positraction differential for your rear axle will be fantastic.
