Are Bilstein 5100 progressive or digressive?

The Bilsteins Pros are digressive. When driving slow they are a bit stiff over bumps. It does make it a little nice around corners on the streets though. Basically they tend to smooth out when you go faster.

What is digressive shock valving?

Digressive valving is characterized by a low flow rate at low shaft speeds. This results in more oil flow resistance. The resistance rate increases as shaft speeds increase, but only to a pre-determined level.

What is digressive suspension?

Digressive is just the opposite of progressive. It starts out stiff, then it tapers off. A progressively valved shock generally will produce a better ride quality, because the shock is softer at slower piston speeds. A digressive shock offers a harsher ride because it is stiffer at slower speeds.

What is progressive damping?

In contrast progressive damping is when damping force goes up more than linearly (=progressive) with piston speed.

What are digressive shocks good for?

Summary: Digressive shocks are bad at small bumps and large bumps, but good at handling and g-outs. Progressive shocks are good at small bumps and big hits, but bad at handling and g-outs. Linear shocks provide the best all around performance.

Is Bilstein 6112 digressive?

Bilstein 6112 shocks have digressive valving, which usually means firmer handling at the beginning range of force (highway, speed bumps). This translates to tighter/sportier handling on the pavement, and then loosening up in more difficult terrain at moderate speeds.

What is digressive rebound?

Digressive rebound would mean that you get more initial rebound damping, which then let’s off the further you get into your travel allowing a faster return. This may or may not be good based on your suspension kinematics.

What is a digressive spring?

Digressive spring rates- generally speaking a digressive spring is a coil spring or torsion bar that is used in an overloaded state which means that it is “losing” rate on deflection. This term is one that is used erroneously when associated with a mechanical steel spring used axially.

How do progressive fork springs work?

A progressive or dual-rate spring is wound closer at one end and further apart at the other. Initial force meets less resistance but gradually meets more resistance as force increases. Since the late 1970s, most road bikes have been fitted as standard with progressive-rate springs.

Why are progressive springs better?

Not only do progressive springs give a smoother ride over small bumps, but they also make the suspension stiffer more quickly as it compresses. They are ideal for a compromise between a spring stiff enough to do the work duty required and one soft enough to suck up the bumps of a rough road.

How long do Rancho 9000 shocks last?

50-100k miles
Rancho RS9000XL Longevity & Durability There’s quite a big range of feedback regarding how long these Rancho RS9000XL Adjustable shocks last, ranging from 50-100k miles. The adjustability of them really go a long way in dialing in the handling or comfort, depending on what the driver needs.
