1997 K1500 rear end

[matuva]

Hi all,

I'm seeking for a 3.73 rear end to replace a worn one on a 1997 K1500. I have the solution of buying a new differential kit + new axle shafts & bearings, but it might be the opportuity to swap to a full float 6 lugs if it does exist and is compatible.

Anybody can share informations about that?

Also, any good adress where I can find a complete kit for disc brakes, with parking brakes?

Thanks a lot for your help

Wohoo, found this : http://www.cutthroat4x4.com/catalog/product_info.php?products_id=55

next step now, find a 8 lugs full float to convert, as long as it can fit on a K1500 and it is a 3.73...

I have a 4.11 full float from a 1 ton. I know you want 3.73 but would make you a good deal on the rear end.

any idea if this one would fit a 1997 K1500? : http://www.ebay.com/itm/01-07-2500-...ies&hash=item51bce1784b&vxp=mtr#ht_457wt_1362

What should I ask the seller to see if it can fit?

I'm not sure if it will fit. I know 1999 1500 will accept a 02 2500 rear axle. If you can measurements on the perch and if they are not the same, then you can always cut them and move them to fit.

Yeah why not. Might consider your offer, I have yet to check the rpo codes on the truck we will have to upgrade and confirm it's a 3.73 or a 4.11

ok let me know. Do you get UPS or FEDEX?

That 11.5" rear axle in the EBAY ad is a MASSIVE piece. The 11.5" rear axle is standard equipment behind the DURAMAX, the 8.1L in the trucks, and all 3500's. The spring perches will most likely have to be rewelded to work as the newer trucks frame rails are set furthur apart unless it's a cab and chassis model.

Newer frames are 42" outside measurements. GMT 400 are 38" outside.

Regarding rear discs I highly recommend TSM manufacturing company for this, just google TSM brakes. Go with the double caliper brackets and install a separate hydraulic caliper and their mechanical ebrake. I tried the Caddy combination calipers first and was not impressed. TSM were great they took back my partly used caddy calipers in exchange for the mechanical units. Luckily just in case I had installed the double caliper mounts from the start.
