Manutec Rocker Roller Spring Kit
Wholesale prices are available to approved account customers only.
Manutec Rocker Roller Suspension Springs (up to 4.5t)
Manutec rocker roller springs are suitable for tandem trailer setups with 60mm wide leaf springs that provide a ride somewhere in between Air suspension and standard rocker suspension.
Individual Springs are supplied boxed, and hangers, bolts and rocker arms are supplied in a separate box.
Below is an image of perfectly installed rocker roller springs. Notice the hangers are stretched as far as possible so the loop is on the back of the holder.
A robust spring for the long haul, ideal for caravans or horse floats, livestock, and other trailers where the ride is required to be more forgiving than standard suspension systems.
When building a new dual axle trailer, it is advisable to allow 10% for consumables and non-consumables as Payload for your customer.
For example, if the desired payload is 3t, build the ATM to 3.3t or 3.5t.
If upgrading, check the capacity of your tow bar.
Great idea to check your tow ball weight for better towing. 5.5% -7% for tandem trailers.
Rocker Roller Suspension Vs Slipper Springs
60mm wide springs twist less and are more robust to withstand better shock loading events like potholes, railway lines, cattle grids and corrugations, to name a few.
If you are considering 45mm wide springs and a cheaper suspension system, you will need to consider whether your trailer will be susceptible to some harsh conditions or merely be a run-around town trailer.
The location of your spring hangers can create problems if installed incorrectly. Read more here.
The rocker Roller Kit includes
4 springs, 2 x centre rocker, 2 x centre hanger, 2 x front and back hangers, bolts, and nylocks.
It is always advisable to install shock absorbers on trailer suspension systems.
