I read the posts re the ways to fix a saggy 4WD and have to say thanks to the previous "posters".

Once again the info on this site is worth bottling!!!

Had polyairs fitted and also had to replace the original leaking / not working GQ Nissan shockers with Old Man Emus. They reckon 9 valves is better that 2 on the standard shocker even if its dearer, and "its a safety issue" right!!!

With the boat, with half fuel on the ball; with its exactly 196.5 kg weight on the drawbar the difference is amazing. Still have to fiddle with air pressures to optimize to outcome but it sure is better.

Not only is the Nissan sitting up at the rear but if feels so much tighter on corners too.

Can recommend to improvement and possums and oncoming traffic will have a lot less dazed lok on their faces too.

Cheers all

Chimo

PS weighing the trailer drawbar was a giggle once I worked out how to do it too.
