Steering Box Selection

[79T/Aman]

you are close. 700/800 boxes have the big round cover on the front and all will be remaned HOWEVER, the ones we sell and those from Sweet and Lee are built boxes not mas production remanufactured as those from the auto part store, equivalent to a custom built engine VS a remaned, that is why the cost is much higher new internals just a used case.
Now you also have new off shore boxes hitting the market, bottom line if the price is not $700 and up for a NEW box they are not worth getting and service parts on some are non existent.
Be aware there are Remaned 600 series boxes on the market now.
Also both 600 and 700/800 can be had in plane cast or plated with the "plating de-jour" ceramic, zinc, gold clear shinny...etc. so it is not a way to tell some charge extra $100 for the platting others plate all their boxes before assembly making it relatively inexpensive.

all US made true 600series/670 boxes will have the R&P servo, look at the picture of the one I posted, the case is plated cast iron but the servo (where the lines fit in) that is a bolt on aluminum R&P servo, others are cast iron to make it cheaper.



As far as the best built 700/800 boxes go you have many choices PTFB PT box, Sweet, Lee, Turn one of the names you know and all of them will be very equal.

There also is a NEW 800 box made for racing, one company even made an all aluminum version, not sure if both are still even available, the trouble is the general public does not know about product unless it is marketed, and some of the best product comes from the true dedicated shops and companies that don't spend a big amount on marketing.
