We suggest to either put your caravan over a weighbridge to get your exact loading before any upgrade.
Furthermore, spring problems, in most cases, can be resolved with a weighbridge certificate and a set of tow ball scales.
Couplemate highly recommends the use of tow ball scales to help you correctly balance your caravan.
Spring upgrades are common on tandem setups. Suspension upgrades tend to re-invigorate your caravans towing capacity to OEM standard in many cases.
Finally, it is common to upgrade broken springs to the next load capacity. However, keep the same ATM intact.
