Nothing really Super about it. It would be best of they had a cooler model designation then just a Granite though.

 Fairly common up here. Most for the Canadian market are ordered and built as single steer with factory tridem drive and have the second steer strapped to the frame for delivery up to Simard suspension in Quebec. Trucks ordered south of the "great white north" have the twin steer factory installed at Macungie. Simard I believe holds the patent on the twin steer design and has a deal with Mack/ Simard for the shared installs.

It's a set up commonly ordered for maximum gross hauling ordered by a few cement companies here in Ontario.

The ones I've worked on are MP7 powered with Allison auto trans and tridem drive on air ride. 

Replaced an SCR can on a "Super Granite" last week. For as big a truck as it is with a mixer on its back, that MP7 and Allison go like heck.

That's the one. Saw a dump set up on U tube like that. Would make a nice heavy haul tractor if  Volvo allowed Mack to have a big six or V8.

The Dump set up on you tube you may have seen was a deal between Mack and Simard to make large tonnage haul trucks in a smaller package....i think they were called Dramis...the first trucks built were on Granit chassis but Simard decided to go with Kenworth and Western Stat as the Chassis supplier.

The truck could haul 55 metric tonne if I remember correctly. 

Had an MP8 engine with Allison trans.

They still put Gold Bulldogs on Pedigree all Mack component ordered trucks.

In Canada, Mack rear axles are not as common any more. There were a fair number of issues with 200 series carriers in the 90s and 2000s that made customers turn to Rockwell/Meritor or Eaton for heavy and highway use. The Mack axles are also more expensive on the spec I believe.  Even in the last 10 years, the Mack axles have seen a high failure rate for how few are being ordered here. I see lots of Mack Axles in the States, just not up here so much.

We have had a truck in the truck for almost 4 weeks waiting for a ReMack Mack Diff all because of the special carrier housing required for the torque rod of the M ride suspension. Unlike other carrier housings, the casting is different for the upper torque rod mount.

The heaviest Macks up here hauling logs etc in the most severe conditions use planatery rear ends not available from Macks product line.

Never would’ve thought I would hear that Mack rear ends weren't any good anymore. It’s been several people on here say the same thing. Sad days 

I thought the same thing. What did they do to turn such a bullet proof product into a dud?

At the time that Volvo acquired Mack Trucks, our own planetary hub reduction axle design, "Planidrive", was long since out of production.

Badged as SR70 and SR80, high-performing Renault planetary hub reduction axles were offered for many years, pre-Volvo.

Finnish Sisu brand planetary hub reduction axles may be special ordered today for severe service applications.
