About the 1973–1991 Chevrolet Suburban
from the generation archive
The 1973–1991 Square Body Suburban proves it's more than a classic hauler — these rigs are out conquering rocky riverbeds, plowing through deep mud, and charging across snow-covered terrain alongside Jeeps and other off-road machines. From custom undercarriage brackets and heavy-duty bumpers to snorkels and oversized tires, the builds shared here show just how far owners push these trucks beyond pavement.
The story
Bought it in exceptional condition 5 years ago with 151k on the ticker. Now the stock drivetrain/suspension all "need" a little "help". I plan to build it into my tow rig/occasional wheeler. I have stock-piled parts for the build that include :
- Offroad Design parts : greaseable front shackles and main eye bushings,FUSH kit, a pair of zero rate add-a-leaves, 4" rear shackle flip, 4.5 rear super shackles, steering box plate and bolt-on brace, 1" body lift kit and poly body mount kit
- 8-lug Dana44/ Corp 14BFF axles w/ 4.10's out of a '76 K20
- JB Conversions SYE kit for the NP241c transfer case
Basically, I'm aiming for Tuff Country 6" front/2.5" rear 56" springs , an overhaul/re-gear of the axles (to 4.8
, a limited slip up front and an ARB out back sitting on 35" swamper radials...to start.
- The stock 350 will be replaced with an Edelbrock MPFI'd Vortec 383 roller motor.
- I'll probably order up a Bowtie Overdrive Stage II 700R4 tranny
- the NP241c will get the SYE as well as the big chain/6-pinion planetary from a Dodge DHD 241 case and a big fat skip-plate
Of course, big stout bumpers/rock sliders go without saying........ — Roostertail
