    I replaced my rear air shocks with Arnott and a Dorman Air compressor. I did not replace rear springs and it rides fine. I am going to get my front struts done.

    Considering a 5.3 to 8.1L CI Vortec 8100 L18 swap for a 2007 Yukon XL 1500 SLT

    The 8.1 is a torque monster but a pig of an engne. A 6.0 or 6.2 is the way to go. Also stay with a 4 speed because of programming, etc...

    What happened to this High Country back seat??

    You can remove the seat- undo the hogrings and put some foam filler pad. A auto upholstery shop is your best bet.

    Rough idle - no codes

    How many miles on the plugs? When I bought my Denali it had 134k miles. One look at plug # 1 and I knew they were the OE plugs. Vehicle ran fine but idle was a little rough. New plugs and wires fixed that. Also i cleaned the throttle body and that helped. These 900's have lousy engine mounts also.

    Exhaust question for 2500 owners

    ‘22 Tahoe LT - 5.3L - Normal Oil consumption?

    The oil life monitor will show quicker use (less life ) for breakin of the engine I would change it when you get to between 20% to 10%. The OLM is a pretty stout program, takes many factors in to account.
