Towing ability of 2004 Suburban 5.3L, 4.10, 4WD
Can anyone give first hand knowledge of the towing abilities of a 2004 Suburban 4WD with 5.3L engine and 4.10 axles? It is 7200 MVGW and has Z82 hd towing rpo. Thanks!

FWIW, you can get a reman 5.7 from Jasper for $2224 plus core, shipping, etc. They also have the 4L60E for $1912. I put in a Jasper reman 4L80E this summer when the Burb died in Murray KY. What I like about the Jasper unit is the 3 year 100,000 mile warranty, and there are something like 2000 independent Jasper shops across the US, so if you have issues when out of town, you can take it to any Jasper shop for warranty service. Buddy of mine is a Jasper dealer in NY and says they are very reasonable on warranty coverage especially if the unit was installed by a Jasper dealer.
As far as the transmission goes, you may do better having yours rebuilt with HD parts by a local guy, if you know a good rebuilder in your area. Just some other options to consider.
From The Jasper website on the 5.7:
We have updated the main bearing from the Federal Mogul RAMP & FLAT
DESIGN to the KING BEARING. This bearing is an aluminum silicon
material. The advantage of the King bearing are:
1. Wear resistance- silicon reduces friction and prevents wear.
2. Fatigue strength- maximum load capacity
3. Improved oil clearance tolerance- reduces noise, vibration, and
excess oil flow.
4. Exceptional corrosion resistance- defends against corrosion for
coolant leaks from intake gasket failures and/or poor maintenance.
5. Outstanding service life- exceeds OEM engine durability of 150,000
miles.
ALSO:
--To improve oil flow and oil pressure, a larger oil pump pick-up
tube is installed. JASPER also uses an undersize cam bearing for
tighter oil clearances providing better oil pressure. This provides
better lubrication in the engine.
--To help provide better oil pressures, JASPER also uses an undersize
cam bearing which can operate in tighter oil clearances. With the
issue of rear seal leaks, the latest design rear oil seal is used. It
has dual sealing lips and dust seals made of Viton / Teflon. This
seal is more durable and with it's use less leaks result.
--100% new head bolts are installed to improve head clamp load to
reduce head gasket leaks.
