The choice of engines, trim levels, etc. is dizzying and somewhat confusing. Note that there are two different rear diffs. avail. With the Z71 Off Road package it comes with a "heavy duty" locker. I thought this was the 9.5" rearend. No! The standard "heavy duty" rear diff. is a 8.5" unit. However, after researching it further I found out the 9.5" extra heavy duty (AXN) unit is only avail. with the 6.0L engine (L76 pkg.). If you want the 9.5" HD rearend you must order the 6.0L eng. in the L76 pkg. Also, with the L76 pkg. the rear brakes are antilock discs (JD9 code) when StabiliTrack is ordered, as opposed to the standard rear drums. The M70 Super Duty 4-sp. auto trans. is also incl. with the L76 pkg. as opposed to the M65 trans. with the 5.3L eng. Also incl. with the L76 pkg. are external auxiliary engine oil and transmission oil coolers. I think this is a good idea and long overdue. Oil is the lifeblood of engines and transmissions. Keeping it cool will help performance and longevity. So, the L76 pkg. has several goodies besides the bigger motor. A good deal if you need these items, the L76 pkg. is $1,095 MSRP/$908 Invoice. You cannot learn these various quirks on the internet sites. They are only clear on the proprietary and very detailed software that the Chevy dealer has.
