Just curious if anyone has had any experience with the GDS 7 blade upgrade for the HX35W? I was wondering if the 7 blade was just more quiet or just a more modern wheel design? It apparently is a superback wheel like the 6 blade. Wondering if it may be an HE351 or later HX40 wheel?

I had a HTT 6 blade H1C years ago... it ran good and whined like a big dog in the cab. But, this will be going on my 93 W350 with more of a tow tune. I'll be the towing my 27' lowboy with the 92 sled puller on the deck, may have many hours on the road next year going to events. I'm just wondering about noise on long pulls over the road with the 6 blade. I want to make some good "clean" power, but need to keep things fairly simple and reliable.

 

ive ran both and the 7 blade is better/quiter. a very good upgrade.

 

The 7 blade is an extended tip wheel. The 6 and 8 blade are old stye wheels.

Here is a link with a map chart of the stand wheel verius the extended tip wheel

The Super 40 uses a 7 blade wheel. The 6/8 blades are standard 40 scale.
