Hq Adj Upper Trailing Arms - Aussie V8 | Holden - Ford

Justin · 29-08-2008, 01:03 PM

After replacing the Trimatic in my HQ with a T700 recently, I was experiencing a driveline vibration that felt like it was tailshaft related. I fitted a set of McDonald Brothers adjustable upper trailing arms, adjusted to @ 10mm extra, and problem fixed.

FYI

did you use an adapter plate to fit the t700 if so did you have to space the converter out aswell?

If you don't mind me asking, how much did the trailing arms set you back??

there about 250 bucks (i think?)

Awesome for setting correct pinion angle, fixing diff misalignments when welded by monkeys, and strength over a factory arm.

They do fixed length bottom arms too if you cant, or are too lazy to plate them (for reducing flex)

If you want to fit a stupid tyre that will rub the front of the rear rail where the bend is, or hit the dogleg as is the case with bigger than a 28 by 10 in a factory tub, you can spec the arms longer and move the diff back some, provided you have enough tailshaft of course...

Do they have a website? Wouldn't mind getting a set of upper and lower arms for my HQ.

No, I used a later model turbo pattern block.

$295 from memory. Money well spent. Pinion angle was too shallow before.
