    What rear axle is in a \'98 K2500 LS?

    Do all 2500s Suburbans have the 14 bolt FF? If not what year/models have them?

    Actually I have yet to see a sub stock with a 14FF, all the ones I have seen had the 14sf. /forums/images/graemlins/thumb.gif

    The ones I have seen with the 14sf have been 350s. I have seen two that have 14ff, both have had 454s! /forums/images/graemlins/thumb.gif The two I have seen were a '99 and a '93. The one I am looking at now is a '98 with a 454. But its about 4 hours away from me, so I can't crawl under to look. The seller has no idea. /forums/images/graemlins/rolleyes.gif

    Daniel get the vin # off the one you are looking at and then call your local GM dealer. They will be able to tell you anything you want to know about the truck. /forums/images/graemlins/thumb.gif

    My buddy had a '96 LS K2500 Burb with the 454, 4l80e and a 14BFF. I seem to see quite a few Burbs of that bodystyle with the 14BFF around here. /forums/images/graemlins/thinking.gif

    For the most part, the Small Block trucks have the 9.5 and the Big Block and Diesel trucks have the 10.5, although some Small Block trucks may have come with the 10.5 as well.

    This is exactly true for 92-00 3/4-ton Burbs. A very strong trend in the pickups too. I haven't seen the 5.7L/14FF combo unless it was in a 1-ton.

    I'll agree with you on the burbs, but... I've seen at least two K2500's (pickups) with small blocks and full floaters. They were however both '92 models... /forums/images/graemlins/thinking.gif Regardless, they must be a pretty rare bird...

    Re: What rear axle is in a \'98 K2500 LS?

    My 454 burb is factory 14FF. All the 3/4's I looked at had that but I was looking for a 454 so did not look at many 350's The couple 350's 3/4's I looked at had the 14ff. They were 4x4. I think a 350 2wd might get a 14 sf but I have never looked at one.

    I do know that a lot of 1/2 tons with the HD towing package got sf 14's It's a pretty common thing to find on a Z71.

    Like Steve said...
    If it's a 454...
    it probably has 4L80E and a 14bff behind it!!!
