    Whats a good replacement axle for a street performance 8.5" 10-bolt rearend? Going to be changing my gears so i thought i'd go through everything while its apart. Just looking for a regular c-clip axle. I was looking through summit and they have a few different ones to chose from. Anyone use the summit brand? Or are they some hong kong ones?? Thanks

    I'm using the Moser c-clip axles with screw-in studs and have no complaints.

    I am running Alloy USA axles and have been happy with them. They came machined for both screw in and pressed in studs.

    I went with Superior brand axles made in USA 4340 chromemoly, listed in the Summit catalog # SAG-EV10-2C+, GM 8.5, 10 bolt, 28-spline they have been in the rear end for five years now and have given me no concerns.
    They were an up-grade from the reg. 1541 carbon steel axles so the cost was higher. They also come with larger holes for screw in studs, I think most of the after market axles are good quality and will last untill you push their limits

    Yea not looking to push the limits of any parts. I just want a dependable car to drive now. Is there any advantage over the different metals in the axles? Thanks

    How much power are you making? I am going to run stock axles until I break one, which hasn't happened yet.

    I think the axles will twist before they break, last rear that I pushed with the 454and a power shift just broke the side axle gears in pieces, and crunched up inside it was a non posi unit so everything went into the garbage anyway, axles had no marks on them
    I think that with better material the axle bearings will last longer with less noise

    IF you use your stock axles (which BTW are perfeclty fine axles for a slightly modified engine) be sure to put them back in the side that they came from.

    Why you may ask? ALL rotating parts have a "set" to them = they get mostly twisted in one direction. IF you swapped the axles from one side to the other, the alxes will try to move the set from one direction to the other = failed axle(s).

    You can't go wrong with either Superior or Moser axles.

    C-clip eliminators on the street: ALL of the manufacturers of C-eliminator kits DO NOT advise using them on the street. Yes, people do and claim that they've never had a problem. I called Moser and asked them why and was told that the seals in the bearing will leak oil if the car is driven more than a 1/4 mile at a time because of heat buildup in the bearings. They advised using Ford housing ends and buying axles with the Ford bearing size on them (along with the bearing/axle retaining plates).
