I read last winter about the drop out cluster three speeds out of KS. I called Dale and spoke with him, and he'd touted his tranny as being able to improve lap times dramatically. Who's actually tried one and how did it work out for you?
If I get good reviews I will be looking for a used one. Please PM me if you have one for sale.

Good luck trying to find a used one. I tried all winter and it seems anyone who has them dont want to part it, including myself now. I bought one new from Skillets Transmission out of Kansas this winter. And I love it. Youre not going to lap the field with it, but I can tell a big difference coming off the corner. Before when I got below someone I needed the little extra to get me by down the straight, this tranny seems like it gives you just that little bit you need. Make sense? They claim 50 horse, I dont know if I feel that, but its definately putting some power to the rear tires. I always run a direct drive powerglide before and shifted on the starts, i was worried with this tranny that in high gear, it would be slower on a start. i was wrong, its amazing on a start. It stays right with the glides.

Is this a lightened 3spd or what? Never heard of it. Curious.

I completely agree with everything frank said. It has alot more get up on the starts but I haven't noticed a major jump in RPM's. I can't give you hard facts because my good motor blew up the first night this year and I have a new backup, but even the backup motor pulled harder on the starts with this tranny opposed to last year. That and the warrenty Dale has really sold me on it.

on a 3 spd when in high gear every thing inside the trans rotates.

thats why people sell lightened gears and removed gear trannys.

a direct drive saginaw is just that, direct drive.

the input and output and a coupler thats lighter than any gear in there and about the size of half a pepsi can is all that rotates when in 3rd.


Mr racing bought a tranny from dale and copied it. according to dale the only thing they could possibly improve is roller bearings in it, which he said would do a little but would also not be as reliable.

i bought mine from dale the original designer, who isnt jacking the price around on us racers to make more and more...

if mr would explain why theres is better and worth a couple hundred dollars more i would be all ears.

We have been building and testing our "direct drive" Saginaw, which we call a
"drop out cluster" trans for several years now. We did not even know other versions
existed until last winter. We feel our design is better than any other company’s versions
for several reasons. We have our base model retailed at $695, with more options that can be added for your specific application, but you get what you pay for. The rollerizing does make these trannies last significantly long over the years. We have replaced competitors
mainshafts from excessive heat, and feel ours do not fail in this area due to the
improvements. Another area of concern that we also have repaired from competitors
transmissions have been the final drive slider hub. We have seen others fail, and
feel our design is better and has a much tighter feel. There are a few other minor
items of design that we have perfected over the past few years of testing and
production. We also offer a long list of options for transmission rebuilds,
especially Saginaws, including REM finishing, gundrilled mainshafts, and full
rollerizing of all gears.
On a side note, a good rule of thumb for rotating weight to horsepower feel is
about 1lb=1HP. Rather than forum response, feel free to give us a call with any
questions. Thanks -Bob M/R Racing (920)-528-7090. www.mrracingequipment.com

There are two ways to make it direct drive both work well one cost more then the other to build . One you will have all three gears forward and one you will only have 1st and third (direct) forward gears some rules at some track require you to have all forward gears and reverse. So check your rules first . I have not heard anything but good things about the trans set up from Dale . I can tell you this if you turn the trans by hand with his set up and then a stock one you will be sold on the less drag for sure. its unbelievable. JUST MY TWO CENTS WORTH

Correct me if I'm wrong, but isn't 3rd gear on a 3 speeds direct drive? people for years has taken 1st gear out, lightend the rest to take out rotating weight, I think you can get these done for around 450

97, The direct drive unit has had the main shaft cut into and the gears replaced with spacers. Then the high gear is situated to run without spinning the cluster gears. So, as it is explained to me, you are spinning less inside the trans. Not only does it seem to reduce the rotating mass weight, but that weight is sitting in 90 weight gear lube.

Dales tranny is GUARANTEED FOR LIFE INTERNALLY.

Dales trans is 550.

Now if someone has a overall lighter unit I might spend some more money for that.

That tranny surely isn't helping you any JohnG. Shouldn't you be working on the nova getting all that forward bite or something? Heck, maybe you can claim someone's transmission at Osky next week, I'm sure there are some good ones in that class.
