WHY MAXI-LOAD

​​

• gives extra load support

• stabilises swag and sway

• reduces body roll

• improves overall ride comfort

• adjustable spring rate

• self dumping property

• reduces vibration

• works like an air spring but without airlines or compressor, does not leak air

• needs less installation space and less accessories than air spring

• easy installation

• progressive spring rate

• silent functioning

• maintenance free

• prolongs factory leaf spring's life time

HOW IT WORKS

​​

Main part of the maxi-load suspension enhancement kit is the maxi-load hollow rubber spring. It's not a simple massive piece of rubber like old style bump stops but a well engineered master piece... The spring rate and progressiveness is realised by proper design of critical dimensions. Main dimensions influencing performance are height (H1), outer diameter (OD1) and inner diameter (ID3). Furthermore the difference of the two chambers (H2, H3, ID1, ID2) play a significant role. The result is a characteristics that can not be reached by either a single spring leaf or by a coil spring: progressive (variable) spring rate, self-damping property trough hysteresis and perfect vibration isolation. But this is not everything, because after selecting the proper hollow rubber spring for your vehicle, the function can be set (fine-tuned) with different spacers (dimension T); when (in which stage) the helper spring should start to act. E.g.: if the vehicle is empty or when the vehicle is half loaded, as you prefer.  

MAXI LOAD HELPER SPRING KIT SELECTION

 

Maxi-load helper springs kits are available for most of vehicles in two options:

 

Option one (v1) is a single or double convoluted hollow rubber spring that can be built into standard vehicles. For this version 3 or 4 different strength levels can be set with spacers supplied in the kit.

​

Option two (v2) is a triple convoluted hollow rubber spring. This option can be built in, if:

• your vehicle is an 4 x 4 (off road) vehicle 

• distance between frame and axle (or leaf spring) is more than 180 mm 

• you carry significant overweight and you intend to lift the rear of your vehicle in unloaded condition

 

If you are not sure, which option you need, we recommend to measure free space for your new maxi-load helper spring, when vehicle is unloaded. See photos below: you can find three examples, how to measure free space between frame and axle / or leaf spring depending on vehicle. (Factory bumps stops are not yet removed on these photos; these weak and cheap bump stops can be replaced by your new and efficient maxi-load helper spring...)
