A friend and I are both wanting to do the spin free conversions kits on our trucks.

Mine- 07 3500 Megacab srw manual 6 speed 6.7
His - 06 3500 extended cab Dually long box maunal 6 speed 5.9

I have been doing a little searching but not a whole bunch. Found four players so far. Dynatrac, Ballistic, Spyntec and Yukon. The spyntec site has no pricing and yukon has zero info. Emailled the both before I posted here...hope to hear back soon.

Anyway. Does anyone have any input on the product? Looks like the Dynatec price is a bit more expensive than the Ballistic kit, and what about sypntec? What do they cost?

Also best places to buy these products Canada side of the boarder? any recommenations?

I have no idea what the Spyntec kit runs, but its a good kit and came with a parts list to ease future repairs. The hubs were anodized for a durable finish and the lugs were already pressed in. Overall, a very good product that kept the antilock sensors in place. I got it for less than the dynatrac and about the same as the EMS, but prices went up after I bought mine.

OOPS

Spyntec kit is $1,550.00 plus shipping, mine will be here tomorrow

i have the dyna trac kit. been on my truck for 4 years and nearly 50,000 miles. absolutely no problems

I did the dyna trac kit myself. 25k miles, no problems. You get what you pay for. You want info, just call them on the phone. They are not a small company and will be there a long time.

What did u find different after the install??? I am thinking about it for mileage and wear reasons.

I found the steering to be lighter and there is approximatly 112 pound of parts that are not turning when the hubs are locked out. I do not keep accurate enough records to say how much fuel I am saving but there has to be some. Also the wear and tear on the front ujoints and diff. And the best reason is so that you can use low range to back a trailer up in two wheel drive. I have the Dyna trac kit ordered directly from them and delivered to my door in Western Canada. I have 48,000 kilometers on the kit since the install and no problems. They were great to deal with.

Less vibes and quieter in the cab. I have Michelin highway tires so any noise or vibe is noticed. I really don't check the MPG the much. I also notice that my old bearings and outer shafts are collecting dust in the garage.
