    When ordering my neaw gears...where have you all found good prices? Summit? Is $150 labor for the rear and $200 for the front a good price not including the parts? I guess that is $350 labor not including the parts I have to buy. And what parts do I need to buy(gears for 2 diffs + the installation kit...bearings etc.)? I'm installing 4:56 ratio. I'm looking for a good place to order this stuff from. Should I consider anything else when doing this change...I've got stock diffs on a 90 Jimmy.

    I have the same setup minus the 35's look below and see. I ordered all my stuff from Jeg's. summit and jegs are about the same price. Summit appearrs to have everything marked .04 less than Jeg's. But Jeg's has always got my stuff to me quick.

    You need to order the gears, the Full install kit, it comes with new bearings and everything you need for the install. You can get the mega install kit which comes with axles bearings and seals. But I found it to be cheaper to get those seals and bearings seperate at the local autoparts store.

    Labor, this is a debatable subject. If you know what your doing and have all the tools, the process should take about 4 hrs (I say about) and that should constitute about $250 average for labor. However, the front will be more than the rear just for the simple fact that almost the entire front end has to be taken apart to get the axles out. IE the hubs, rotors, spindles, bearings, the works. Then it has to all be put back in.
    So if your getting the rear done for 150 and the front for 250 your getting a great deal PROVIDING the person doing it knows what they are doing.

    The job is not rocket science, it just takes, LOTS of patience.

    Hope this helps. Also HEED the break in instructuctions.

    Will work for beer, parts and tools.

    Best prices that I got was from Drive Train Direct. Right at $500 for front and rear gears plus the install kits for both. Mention Colorado K5 and Steve says you'll get a 10% discount. You can look up there number by going to their web site www.drivetraindirect.com. If you have a quote for $350 to do both front and rear, go for it. I was quoted $250 for the rear and $350 for the front (front has more to tear apart and reassemble) plus about $100 for the consumables (lube, gaskets, etc.).
