2010 chevy suburban LT 4x4 towing capacity versus 2010 tahoe LT 4x4 towing capactiy which is better ? My Jeep is a Modified 89 2 door XJ CHEROKEE LIFTED,custom made which bumper up front, trussed front axle, fully caged and locked on 35" tires on steel wheels..... Custom built Trailer is over the wheel mounted flat bed....

 

No contest. The Suburban will have a higher rating and will be more stable/more pleasant to drive because of the longer wheelbase.

 

thx a bunch for ur reply to my question!! Any idea what all is upgraded when they say it has the the Z71 suspension VS just 4x4 suspension ??

 

Rancho shocks, hill descent control, transfer case shield, a locking rear-diff. Supposedly more off-road capable. Plus all the interior extras. It's like an LTZ+.
If your looking for payload they made a 3/4 ton 'burb up til 2013. Bigger motor, transmission, brakes (w/ hydro-boost).

 

I'm pretty sure Z71 is just more of an appearance package - not really any serious upgrades. At most, it has skidplates and maybe some better/stiffer shocks. Certainly nothing that would impact towing ratings.

 

From trailerlife.com for equivalent 3.42 rear ends, 5.3 liter engine, trailer package, cooling package and 4 wheel drive:

2010 Suburban 7900 lbs
2010 Tahoe 8200 lbs

Tahoe wins in this case. It’s because it’s dragging around less weight. However, we all know Suburban’s can be optioned out to tow more. My 2008 3/4 ton can tow 9300 lbs.

longer wheel base will tow better....better sway control
