I am wondering about these quick change rear ends. I found them advertised on e-bay and I'm curious to know if anyone here has one or has dealt with the company. Here is a part of the ad: The perfect Hot Rod Rearend, Speedway Engineering Super Max Quick Change with Wilwood brakes & 40 Ford Axle Housings. 31 Spline Axles, 5 x 4 1/2 bolt pattern 3.56 Gears 56" overall width 12.19 Wilwood Brakes w/Park Brakes & Polished Calipers How do they compare to say a new Winters V8 Quick change ? Any info or experiences you can share would be great. Larry.
I used speedway engineering rear ends and front hubs sway bars for a long time , quality products, give frank zapper a call at speedway engineering , great guy who knows his stuff for sure , as far as winters products they are very good products as well , both companies have been in bussiness for a long time ! That alone should say it all !
Thanks, the guy who responded to my inquiry is named John. Must be a dealer because he is in Arizona.
Just another of my "Should I drop the $ for a Quick change ?" threads Can't seem to make up my mind. Have a perfectly good 8" Maverick rear fitted in my RPU now, it's just that the QC is so cool. Might be good behind my Y Block. I just don't know
The Super Max will handle all the power that Y block has with no issues - I've just never been in love with the look of these - that squared off, 10 bolt rear cover just doesn't have the style of a Halibrand. Mind you, I don't like the style of the Winters either...just my 2 cent opinion. Steve
Speedway Engineering is a good company with great products. As I recall, the Supermax is sort of unique. The ring and pinion is not the same as anyone else's and it is in between the V8 and champ sizes of other companies. This is no problem if you are buying new, but limits interchangeability if you are building one from parts. Whether you are buying new or used, step up. That old Maverick rear end will NEVER be a Quick Change!
Blue - Best answer...call Speedway..! Ask them these questions. As has been said, Speedway has been in buisness for many years building race car parts. I've been to their shop, a place where a kid could get lost in cool parts. Mike
Great company and knowledgeable about QC's. They have a new one that uses the early Ford axle tubes. I have used them for a long time for machine work. QC's are not cheap or quiet but they have the look I love in a hot rod.
Are these quick change rear ends 100% lockers or are they availble with tru tracks or similara more suitable for street driving?
They will build it however you want, locked, locker or limited slip. There will be a price difference between them depending on the option. Speedway is a great company, good stuff.
I called them and was told they needed my axle housings and there wasn't enough room for a limited slip diff.so it came with an open diff.I thought that shipping my axle housings to California and the shipping back to New York would be to much.I decided to go with a winters which has a limited slip diff. ,shipping to the closest terminal was just under $100.
