Single Rocker Roller Spring – Galvanised

Galvanised Replacement Rocker Roller Suspension Springs (up to 4.5t)

The galvanised replacement rocker roller spring is galvanised to help prevent corrosion and suit spring lengths of 687mm from tip to tip.

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.
