Dana 300 Big Shaft Kit (http://webpages.charter.net/saw056/onetime.htm) Made in the :usa:

i don't know much about 300's but that looks like a good thing

[TJ Fan]

So...just curious...any difference between yours and the Advance Adapters units (or are they one in the same:D )

[Keith Bailey]

Please go to the Vendors showcase which shows the differences between my big shaft kit and others. Thanks

$?$?$?

[Keith Bailey]

They're going for $490 Retail. Call or email for other pricing. Our email is here. (offrd@bellsouth.net)

[Jeepskickass]

So will this work on short 300s, or just the long shafts?

[onetoncv]

i'm thinking someone needs to make the 32 spline front output a little more- but its a nice looking kit- Jesse

[Keith Bailey]

Hey the output shaft will be available through JB Conversions and also the kit only works for the long shaft but I will ship you a Dana 300 with the short shaft installed for $700.00. Then you could sell your old one to make up some of the cost.
Thanks
Keith

nice piece I just wish I could have waited but I had to go AA

[onetoncv]

Just wondering is yours any different /better than advance addapters- ? and your flange we talked about I hope its not just like mine- (Patented ) Jesse :D

So, this heavy duty 32 spline shaft that is made from aluminium is somehow STRONGER? than a similar sized steel shaft? :flipoff2:

I guess that metallurgy has change a lot since my classes in the 90s :rolleyes:

Goods nice though :D

[Keith Bailey]

The housing is heat treated aluminum; the shaft is 8620 heat treated alloy.

The AA kit is a good kit and we don't know of any failures. We feel our kit is better for the following reasons.

[Keith Bailey]

The AA housing is not designed for the attachment of an ebrake. Our housing is beefed up heavily to handle the load generated by the use of ebrake components. The result is a stronger housing.

[Keith Bailey]

We also spot machine each bolt seat location so the bolt head pulls down level on the housing and doesn't create stress that could crack the housing. The "draft" required to allow the part to release from the mold causes the casting to made with a slanted surface here (ours and theirs). This results in the bolts making point contact instead of flat contact. With our spot face, the point contact never happens.

We also use an aluminum match-plate mold instead of a wood/sand combo. This is a fully machined mold that yields a precise casting. Look at the edges and corners of our housing and you can see the difference (1st four photos attached). You can also see the two dowel pin holes used in conjunction with 6 tapered head cap screws to secure the ebrake bracket.

Our housing (bottom) has a much more massive casting as you can see here in a comparison of the top of each piece.

We also use an angled drill on the CNC to create the vent/drain back hole. We don't drill through from the outside and fill the hole with a push-plug. Look at the upper side of the competitors housing and you will see the cap plug siliconed in place.

[Keith Bailey]

We go all-out on the shaft also. The shaft on the right is ours. We fully grind the shaft except of areas with splines. We pay attention to machining detail and make sure the spline runout doesn't get into areas of the shaft not meant for splining. You will notice no spline cuts below the lower snap ring on our shaft.

[Keith Bailey]

Any area of the shaft that contacts a gear is precision ground on our shaft. The shaft on the right is ours. You will notice a grinded seat area above the lower clutch spline on our shaft. This is the area where the helical gear contacts during operation. We grind the surface within 0.0005" to provide a smooth seat for the gear.

Uhhmm, yes and no from the way things look. Looks better, actually. :D

[onetoncv]

well yours does seem to be thought out - and seems swell -but if there was a large/any problem with aa's breaking- wearing/distorting /anything of this nature - then i see a need- ??? Have not seen any of the sort going on- nice to have a competitor for aa- Jesse

[cmk]

So, it's a "me too, better."

... nuthin' wrong with that.

... except I need one for a short tail d300.

Reply to Jesse;
As I mentioned we don't know of an AA failure either however we don't feel the need to experience an AA failure in order to surpass their design with our kit. The main goal of our kit was to create a housing that was designed with the intention of running an ebrake without the need for add-on brackets or braces. If you're not running an ebrake then you get the beefier housing by default (consider it a gimmee!). As far as the flange goes, we didn't even look at yours as we wouldn't want to get in the way of your patent. We did however look at the 1350 CV flange found on our NVG271 tcase in our two company F350 Superduty Fords. As you may know, the Ford flange uses the same spline as our shaft and a 1350 cv driveshaft to match. With this idea, we designed and created our own flange with the bolt patterns, diameters, etc. that we needed. We have also used the front flange off of a NP231D mounted directly to the front output of our stock Dana 300 to allow for a 1350 CV driveshaft.

If you would like to handle an additional shaft kit than the AA version, give us a call. We would also be interested in doing a internet group buy combined with your driveshafts.

your on the right track- but i certainly hope your going to make a living doing it- there's not a huge demand for the dana 300 kit- i think i have sold maybe 25 of these in the last 5 months- did i hear anything about this fitting the atlas also? might want to check rights to that claim- Jesse

[Keith Bailey]

Jesse
Not sure I understand the "make a living" and "rights to claim" mentions. Please explain.

Keith,

Some constructive criticism for you:

The attention to detail is evident in your kit. However, in general, people are only willing to pay for a certain amount of quality. A/A's kit seems to have found that level of quality and at a good price.

Case in point; I was able to order both an A/A kit and patented 1350 series 32 spline flange from Jesse @ High Angle Driveline for significantly less that the retail price you quoted earlier in this thread.

If you can bring your advertised pricing down to a level more competitive with A/A and make the minor modifications necesary to make it work with the short tail d300's, I think you'd have a "home run" on your hands.

[Keith Bailey]

We appreciate the criticism. We depend on the public to buy our product so we are always interested in other view points. There is more machine work in our kit than AA, more aluminum in the casting, and more time on the mill. To make the kit the same price as AA would mean we would have to decrease some of the above. The only way to do that is to make our kit the same as AA therefore eliminating some of the improvements. We don't want to do that. We have already sold these kits and have no regrets by the users on what they spent. If the AA design fulfills your needs, keep your extra cash in your pocket. If you want the improvements we offer you will have to cover our added cost in providing them to you.
Making a kit which will suit the short version of the Dana 300 requires a new pattern and casting. If we get sufficient call for this application, we will make the part. As previously mentioned, the aluminum match-plate mold type we use is very expensive compared to the mold type used by AA. We regret we cannot offer the kit you need however at this time we can't justify the new casting without more consumer need. My advice in your case is to buy AA and I'm sure you will be quite satisfied.

I suggest you do some more research on this matter. Making your kit work with the short tail cases is quite easy and does not require a new pattern or mold. You can easily accomplish it the same way that A/A does (by modifying your existing casting).

[Keith Bailey]

Again, we don't think the way AA does their kit is the best way. The housing design we would make for the short version is such that modifying our existing piece would not yield as nice of a part. Believe me ; we have done our research and then some but thanks for the suggestion.
