What do numbers on Ohlins spring mean?
The first set of numbers “01092” reference the series of the spring. The series is the actual nominal dimension that this spring is designed and manufactured. In this example a “01092” series spring is made to a 57mm Inner Diameter (ID) and has a Free Length of 170mm.
What weight is Ohlins spring?
Spring stiffness guide based on rider weight

How do you read shock spring numbers?
Spring Length: Springs for coil shocks are rated using two numbers (you will see these stamped on the spring, e.g . 450 X 2.25). The first number is the weight (in pounds) needed to compress the spring by an inch (aka spring rate – see below) and the second is the travel length of the spring (in inches).
What weight spring should I get?
Springs should typically be compressed 25-30% of the free length when supporting the weight of the vehicle.
How do you calculate the weight of a spring?
Calculate Wire Length
- – Determine Mean Diameter (D) Add one wire diameter to the inner diameter or subtract one wire diameter from the outer diameter.
- – Multiply mean diameter (D) by 3.1415 (Pi).
- 3.- Multiply #2 by total number of coils (N)
How do I choose a coil spring rate?
When attempting to determine the correct spring rate for a car, the trick is to set the ride height so the chassis rests in the shocks’ sweet spot within this small 3- to 4-inch window. A solid-axle rear suspension, on the other hand, is a bit more forgiving.
How often do coil springs need to be replaced?
How Long Do Coil Springs Last? There really is no set timeframe at which coil springs expire. A lot of coils last for the life of a vehicle, while others break down sooner. 2.
Does preload increase spring rate?
Preloading is not the same as using a stiffer (higher spring rate) spring. Preloading does not change spring rate but preload does change the force to start moving the shock and high preload dramatically reduces shock performance over smaller bumps and makes for a more harsh ride and worse traction.
