If you value your tailshaft and diff, speak to Herrod about their aftermarket leafs.

Otherwise speak to a suspension mob.. Pedders.. Wholesale Suspension... etc etc.

They might be.... Dunno who makes em... But they apparently developed their own design to keep the pinion angle correct when lowering.

Helps keep the CV's in the tailshaft from popping and costing the owner a new tailshaft.

Read a bit about them on the XR6T forums.

So the old spacer blocks for leaf springs are now a thing of the past?

No, they are still there.

But people have been popping tailshafts using them in FG's.

FG's use CV joints in the tailshaft rather than uni's, and their range of motion is far less than the old uni's.

People are popping tailshafts in stock form due to the high diff movement under power and limited range of the tailshaft joints. Lowering the thing only makes it happen quicker.

So crucial flaw in design for something that should be able to carry one tonne or nothing on the tray and work through a huge angle with varying loads? Still to this day I fail to see why the one piece tail shaft was a bad idea... Mine has no CV or uni joint in the middle and hence gives no trouble and hasn't for the last 330,000 km... Why do people insist on complicating things these days? :?

Cheers,
Tim

Yep, massive design flaw... And one that was picked up during durability testing at the proving ground.

Not the lowering, but the exploding tailshafts under high power loads, due to excessive pinion angles for the CV's.

But Ford decided to push ahead anyways.

Its not the CV's rather than the diff wind up causing excessive pinion angles under load. Lowering the vehicle makes it worse. Thicker springs will fix it but will cause a harder ride. Strap a camcorder under the vehicle towards the diff and give it a bit, you will see what i mean.
