Adjustable Ride Height
When it comes to adjustable ride height, the Bilstein 5100 series shocks have a clear advantage.
With the 5100’s, you get up to 3 inches of lift by simply adjusting the spring seat. This allows you to dial in the perfect ride height for your needs.
On the other hand, the Bilstein 4600 only allows for stock ride height. While the 4600’s provide a comfortable, controlled ride, if you’re looking to level your stance or gain extra ground clearance, the 5100’s are the way to go.
For off-roading or overlanding, the additional adjustability of the 5100’s can make a big difference in clearing obstacles.
To adjust the ride height on the Bilstein 5100’s, all you need is a wrench to turn the spring seat at the base of the shock.
Each full turn of the spring seat equals 1 inch of lift. The shocks do not require disassembly to make the adjustments. You can easily raise or lower your ride height based on your driving needs.
For daily driving, the stock height of the 4600’s will likely suit you fine. But for those wanting more flexibility, the 5100’s are a great choice. The adjustability allows you to quickly switch between heights for different road conditions or when going from daily driving to off-roading.
It comes down to how much adjustability and flexibility you want in your ride height. For most, the Bilstein 4600’s standard height will work great.
But if changing heights for various needs is important, the 5100’s take the win here with their 3 inches of easy adjustment. The choice is yours!
Damping Technology
Bilstein 4600 and 5100 shock absorbers utilize different damping technologies to provide responsive handling and a comfortable ride. T
The 4600 features a monotube design with a single cylinder and piston. The 5100 uses a digressive piston with a multi-stage design.
The monotube shock in the 4600 has a larger diameter cylinder that holds more oil, allowing for better cooling. The single piston also has more surface area, which improves damping control.
It results in less fade from overheating and more consistent performance. The downside is that monotube shocks typically provide a stiffer, sportier ride.
The digressive piston in the 5100 has a two-stage design with different sized pistons and valving. The larger main piston handles small road impacts, while the smaller secondary piston engages during larger hits for added compression damping.
Its multi-stage design aims to deliver a smooth ride over various road conditions. The secondary piston can also be adjusted to change the ride from soft to firm. Compared to a monotube, digressive pistons typically offer better comfort and adjustability.
So which design is better? It depends on your priorities. If performance and handling are most important, the 4600’s monotube shock may be ideal.
For a balance of comfort and control or if you want adjustable dampening, the 5100’s digressive piston could be a great choice. Of course, there are many other factors to consider between these two models.
But when it comes to damping technology alone, it comes down to the type of ride and handling you prefer.
The Bilstein 4600 provides responsive performance with its monotube design, while the 5100 aims for comfort and adjustability with its digressive piston.
Choosing between the two depends on whether you favor an athletic ride or customizable comfort.
Valving
The valving in a shock absorber controls how quickly the damper reacts to impacts and how stiff or soft the ride will feel.
Bilstein’s 4600 and 5100 models use different valving technologies to achieve their performance goals.
Monotube Valving
The Bilstein 4600 uses a monotube design with digressive valving. This means the valve has different sized openings that progressively open and close based on the speed and force of the impact.
For small bumps, the smaller openings restrict flow to firm up the ride. During bigger hits, the larger openings allow more fluid to flow for maximum damping.
This split-second adjustment helps the 4600 feel responsive yet stable over various road conditions.
Continuously Variable Valving
The Bilstein 5100 utilizes a monotube body but adds continuously variable valving. Rather than having set openings, the 5100 has flexible disks with slits that can open wider or narrower.
A coil spring applies pressure to the disks, controlling how much the slits open. When the shock is moving slowly, the spring holds the disks nearly closed for a firm, sporty feel.
At higher shaft speeds, the disks flex open to allow more fluid through, optimizing damping for bigger impacts.
- This variable system is more advanced than the digressive valving in the 4600.
- It provides a wider range of damping adjustments to handle both small and large bumps with more precision.
- The ride can feel more responsive and planted due to the higher level of damping control.
The valving technology is a key factor that contributes to the performance difference between the Bilstein 4600 VS 5100.
The 4600 offers solid, balanced performance for daily driving and light off-roading, while the 5100 provides a more tunable, track-inspired ride for performance driving and motorsports.
For most casual drivers, the 4600’s valving will work great, but driving enthusiasts may appreciate the higher level of adjustability offered by the 5100’s continuously variable system.
