    Ok guys, I've got a 2006 Tundra TRD 4x4 4.7L Double Cab. I'm interested in the bilstein 5100, I'd like to lift the front to the top which is 2.5" A few questions,

    1. Do i need to do the diff drop at the 2.5" ?

    2. Should I install 1" rear blocks in the rear?

    3. Has anyone had any issue with leaking CV boots? Thanks for the Info guys!

    more than I can list here
    1. You should get a diff drop

    2. Rear lift is subjective. Do the front first and decide how much if any rear lift ya want.

    3. No

    Agree with dirtydeeds.
    Dif drop recommended.
    Check after front lift. Should be ok without.
    No on a 3" front lift after 2 years

    Hey guys, I don't mean to jack this thread but I have a question. I've lifted a truck I previously had 2.5" in front and 1" in the back but didn't know about the differential drop. How difficult is this and is it necessary if I have a 2WD?

    There's no differential to drop on a 2wd truck.

    Why is it necessary to get a different drop? Now I'm wondering if I need to get one now

    It is necessary to keep your CV angles where they need to be. Think of it this way, you lift your truck, that means you lift the motor, transmission, front differential etc. but your wheels and tires stay at the same height. Now your front axle shafts are angled down. This can and will cause premature wear and lead to failure of the CV joints. Now if you drop you front differential relative to your lift size your angles will retain factory. Hope that makes sense.

    Diff drop recommended at 3" and over lifts on 4wd trucks only. With 2wd there is no diff to drop. Its an easy install. Unbolt two bolts, rotate down, add the spacers, install new bolts. Also only costs about $30.

    I talked to a 4wd shop today about doing 5100's all the way around. He said that I wouldn't need a diff drop. He did reccomend a 1/4" shim on the front. He also said that he preferred the Pro Comps to Bilsteins. They're almost the exact same price. Any thoughts?

    I had the Ultimate lift kit on my truck for over 2 years. It uses the Bilstein 5100s as the shocks. The difference is that it has machined parts on it that convert it to a fully adjustable coilover. They were nice shocks. Good ride. Definitely an upgrade from stock and much better than the stock TRD shocks with spacer (had that on when i bought by truck used).
    Only issue i saw was someone adding a spacer to the top of the shocks for increased lift which caused failure of the shock. The reason is it was used inappropriately. Would happen to any shock designed for a certain lift. The bump stops were not extended and this lift on top of lift caused the shock to bottom out and buckle.
