4Runner 6112 Vs 5100: Detail Comparison

The 4Runner 6112 and 5100 shock absorbers have been popular for many reasons. However, if you want to get one of them for your 4Runner, it is best to compare them to know which one will work better for you.

So let’s find out!


The construction material of the shock absorbers plays a vital role in their performance. And in this case, both 6112 and 5100 have high-quality and durable materials.

While the 6112 is made of high-grade aluminum alloy, the 5100 is made of steel. Since aluminum is lighter than steel, it offers more control and is more durable.

The pistons’ rods of 6112 are made of chrome-plated steel, and that of 5100 is made of stainless steel. The advantage of stainless steel over chrome-plated steel is that stainless steel is more resistant to corrosion. 

But the good thing is both shock absorbers come with zinc plated finish, and it works as an extra layer of protection against corrosion. This type of finish also ensures the material remains protected in harsh weather conditions.


The size difference in both shock absorbers greatly impacts their performances. The 6112 has a 2.65” body and a 60 mm piston with an 18 mm rod. And the 5100 has a body of 1.95” and a 46 mm piston with a 14 mm rod.

The larger body and diameter of the 6112 shock absorber allow it to store more fluid. It also moves the fluid more efficiently to the piston, ensuring better-damping force. Moreover, because of its larger size, this shock absorber dissipates heat and offers more consistency even during long hours of the ride.

But the 5100, with its smaller size, cannot dissipate heat as well as the 6112. That is why, while it is still suitable for many off-road rides, it always ends up with certain limitations.

Adjustability/Lifting Capacity

Being able to adjust the shock absorber is beneficial in many ways, including ensuring the vehicle performs well regardless of the road condition. And in this case, the 6122 shock absorber comes with an adjustable feature that lifts about 2.5 inches and has 5 height settings.

And the 5100 one has a maximum of 2 inches of lift with 3 height settings. That means this one has some limitations compared to the 6112 when it comes to adjustability.


The spring design and features play very important roles in the shock absorber’s performance. Having a better spring design is essential for a vehicle’s improved performance and consistency and smoother riding experience.

As for 6112, it has a monotube and coilover spring design, which is effective for more precious tuning and increases durability. And the 5100 has a coil spring that is installed separately. But it also offers a flexible ride.


The 6112 shock absorber is constructed in a way to work with Coilover, which is why it is made slightly stiffer. This feature ensures a firmer ride. And that is why the 6112 is more suitable for heavy off-road use.

However, unlike 6112, the 5100 is softer because it works only with an aftermarket spring coil. And it is also beneficial for a smoother ride on bumpy terrains.

Off-Road Performance

When it comes to performance, both 6112 and 5100 are pretty exceptional. However, one of them is just better than another. With a 60 mm piston, the 6110 shock absorber has to put less effort than the 5100, which has a 46 mm piston.

Moreover, the damping surface area is around 25% larger in the 6112. As a result, the 6112 model ensures better control and less bumpy ride off-road.


The cost of these shock absorbers is what makes one of the most significant differences. The price of the 6112 shock absorber is quite high compared to the 5100. The exact price of both can vary depending on several factors, such as location, retailer, special offers or discounts, etc. Nevertheless, the 6112 is likely to cost around $540-$950, while the 5100 may cost around $450-$475, or maybe more or less.
