BT50 Saxo Spring

Fitting any sort of "helper device" may lift the rear but the stress on the chassis just in front of the rear spring front hanger will cause the chassis to either flex badly or just plain break.
The correct solution is to lengthen the chassis to get the rear axle under the load. If the load is mainly behind the rear axle you create a see-saw effect as the load tries to lift the front wheels off the ground.
The job costs about $6k but the difference is worth every cent. Experience talking.
If you are not sure just search the web for broken dual cab utes.
Think carefully.

I had the rear springs in our BT 50 retempered and an extra leaf fitted. The job was done in South Grafton. The rear was lifted 100mm. Their is no rear end sagging with the van on now.

I was told prior to getting the job done to stay away from after market springs as most of the are rubbish.

Thank you. I am reluctant to buy new springs and had not considered tempering. I am not looking for much of a raise - just to limit the sagging. My ball weight is only about 160kg and I keep the weight in twin cab in front of or near axle. Have previously used airbags and the Equalizer helper in the Ranger with no issues. I have witnessed bent chassis etc. Might investigate tempering here in SA.

Thanks for info. I am not a huge load carrier and do keep weight in front of axle. Airbags and Equalizer have seen me right for last few years. I kept the bags at around 30PSI (they were rated to 100PSI) and the helper spring on the lowest (least) pressure. I have witnessed a bent chassis and have followed some of the issues you are referring to. I might need to re-consider. Feedback on this forum really appreciated.

Thank you. Will give them a call.

Hi there, my experience with Sax was not good see HERE for the details.

When things go wrong, they go wrong! Unfortunately, manufacturers/suppliers generally have no empathy or understanding of the grief and expense incurred in these circumstances. We experienced similar (but not as bad) with, at the time a new 2012 Ranger that accompanied us on the CSR. Ford had no idea of the impact they had on that trip owing to a incorrect battery management system that two Ford dealers stuffed up. Hence, I now keep clear of Ford vehicles. I was provided with two incorrect OME shockers for my vehicle which just caused us to bounce everywhere. I doubt I will refit the Equalizers although they worked OK on the previous vehicle.

I had the same problem, I did not want to have my truck driving like a dray if I fitted heavier rear springs so, after much research I fitted a set of " Supersprings".They are a patented system from the USA that are sold in Aust via TJM.They are available in 300gk,600 kg and mine spec.
They only engage when there is a load on the tray,meaning, the truck drives as before and when the camper goes on the back the Supersprings progressively kick in responding to the actual load.
They are relatively cheap, easy to fit at home,and work extremely well.Of course, you must also be carefull with the GVM, but, I have found then great bit of kit.They stop most of the rear sag, don not affect the drive characteristics of the Yoot, all up, well worth a look.

Will have a look. Could be what I need as I am not an "extreme" load carrier, and while the BT handles the van - I have only done so without a full load. I think a bit of help will be required - the main question is what, within a budget. Cheers
