80/105 Series Tough Dog Caster Plates

[oondy]

I have just supplied a set of TD Caster Plates to a mate of mine (he builds offroad stuff so he knows what he's doing), so he could install the plates in a customer of his with a 105 with 4" lift.

The plates have rotated the diff back way too far and now the tie-rod to touch and foul on the radius arms. Even if it had a bigger lift in it, the relationship between the radius arms and tie rod wouldn't change.

I went and had a look at it and it's all installed as per the instructions.....what are TD thinking...honestly.

The TD part number was TDCP-006 which is the only caster plate kit listed by tough dawg.

surely this can't be right, if it is well then its another negative mark for TD my book - and there's a few already.

has anyone else had issues with these plates?

cheers

Not 100% sure, but IIRC someone on here bought a set and needed to redrill them.
Anyone shed any light?

[Kev80]

Yep, same problem here.

Thinking back im sure they are TD ones too.

[oondy]

How can TD sell a product like that then??

they really do overprice and over rate ALL of their gear. When they RRP a set of caster plates for $250 and still have to modify them because their design guys are a bunch of w@nkers...realy makes yo wonder about the whole shebang realy.

Those plates are for a 6 inch lift. six not four.

[oondy]

regardless of the lift - the whole diff rotation/position respective to the radius arms would be the same with these plates - but yes it does have too much caster for a 4" but even if 6" coils were fitted - the diff rotation/position, with the plate fitted, comes from back at the chassis mount of the radius arm - NOT AT THE DIFF END ITSELF.

Some 80s and 100s seem to have different castor angles from factory. A mates 80 had only a 3" lift and the castor was 3 degrees negative so it needed 6 degrees plates to return it to factory settings. You are right though you could remove the whole diff, radius arm, steering linkage assembly from the car and the steering arm is still hitting the arms. We had the same problem and the seller told us to grind the radius arms for clearance F#*k that! Every brand of plate does the same thing because 5.5 degrees is the least you can rotate the diff to keep clearance from the radius arms to the sleeve they supply that goes in the top hole. We returned the plates and I re-drilled the factory brackets then made some stepped washers to fit in the new enlarged offset holes. For every 3mm you move the front hole down you will rotate the diff 1 degree.
