The DB4 is a new generation professional dynamometer, optimized for testing suspensions of motorcycles, cars, atvs and mountain bikes. Thanks to the 4kW AC-Motor, it allows you to test shocks and forks in a wide range of speeds and loads, choosing between several stroke settings. The DB4 is an essential tool that allows any suspension operator to visualize shock’s and fork’s Load vs Velocity graph, compare different click settings and valving options, detect fork and shock anomalies, like cavitation.It includes a state-of-the-art real-time dedicated controller board that ensures a stable and reliable automation and data acquisition, while the software provides an intuitive graphical interface and simple but powerful tools for suspension analysis, compatible with the most common operative systems; it’s plug-and-play and does not require a dedicated laptop. Despite its compact design, DB4 allows you to fully characterize the suspension, thanks to the graphical and numerical outputs of the software and its sophisticated algorithms.The software includes several graphs: Peak Velocity, Displacement, and Hysteresis.It also provides the following outputs: gas preload, gas-spring rate, and static friction.Custom versions of the software can include hysteresis analysis, dissipated energy, damping coefficient calculations, etc.


The DB4 PLUS is the higher-power version of the DB4, optimized for testing suspensions of off-road bikes and cars.Thanks to the powerful 5.5kW 380v AC-Motor, it allows you to reach higher speeds and forces compared to his smaller relative, the DB4.The DB4+ is the perfect tool for specialized technicians who need to characterize high force or high speed suspensions.The improved mechanic will allow to get where the DB4 can’t take you.

Same software, just more power.

Discover our DB4 Suspension Dynos



To obtain optimal performance, on track as well as on the road, every detail is important. With
the Dyno line, our mission is to support your continuous seek of perfection providing you with the best measuring instruments dedicated to motorsport. After SuspensionDyno, dedicated to the accurate measurements of the
damping force of shocks and forks , we developed DS1 , the first instrument dedicated to the full characterization of every elastic element of your suspension all with one single instrument!

Measuring these elements is even more important in today ’s suspension technology, with the advent of many non linear elements that contribute to the optimal setup of modern suspensions such as linear and progressive springs , air springs, air bumpers in forks (oil level), rubber bumpers, leaf spring, and more. Thanks to a versatile design, and a modern interface based on a touch screen and wireless data transmission, DynoSpring is the ultimate spring rate measuring instruments for suspension professionals.



Thanks to its Thirty years experience in the Suspension Industry,  Andreani Group has developed a series of Tools and machinery to let Suspension Workshops work in a effectiveness and professional way, on every kind of suspension. Made using the best materials available on the market, the tools are available singularly, as complete kit or as Packages divided in: Universal ToolBox, track/Street Package and Off-Road Package.

This machine is made to vacuum shocks using the switches on the front of the machine. The process occurs manually by driving the appropriate hydraulic controls. The machine has two manometers: the first one to verify the oil pressure; the second one to verify the vacuum inside the shock absorber (Vacuometer). The Vacuum Pump is provided of two identical tanks to use two different kinds of oil or to keep one for the used oil without opening the shock absorber. Easy to carry with two practical handles located on the sides of the machine.


This pump allows to vacuum and fill all shocks automatically, with an easy-to-use software, and to control all passages thru a display located on the front of the pump. The pump is provided of two identical tanks, to select the kind of oil that can be used for the filling process. The proper capacity of the tanks allows to work with car shock absorbers, as well. Large tool compartment on top. Vacuum Pump SP4 is light and easy to carry with two practical handles located on the sides of the machine.


Light and easy to carry, SP5 is the most innovative vacuum pump that Andreani Group developed to make easier, more precise and more efficient the filling and vacuuming of shock absorbers of any kind and brand. The process is totally automated, thanks to an easy-to-use and extremely efficient software provided of a more friendly interface to follow all the steps thru a wide touch screen display that checks the process in real time with information and intuitive graphical. All the standards are managed by the advanced electronic system, including the oil level in the two inner tanks that are big enough to work also with cars shock absorbers. On top of the machine there is a handy space used to store working tools.
