(password with purchase)

Designed & manufactured in Oregon by a gear head engineer for gear heads!  

The standard kit bolts in with winch in the “High Configuration” with winch line exiting through the bumper (requires cutting a hole in bumper)

The upgraded kit allows the customer to install the kit in "High Configuration" as above OR in "Low Configuration" with winch line exiting just underneath the bumper - requiring use of a hawse style fairlead.  With the upgraded kit, you can change it anytime by unbolting it and flipping the kit into the other configuration!

Note that the winch mounts upside down in this kit - check with your winch manufacturer on capability of your model winch to be operated & installed upside down.   

The BBWM will BOLT into 81-87/‘91 square body 4x4 GM trucks and is compatible with 81-87/‘91 square body OEM hooks as well as Engineered Vintage Shackle brackets (sold separately.   Note there is a 10% discount on 81-87 Engineered Vintage shackle brackets (non hardware) when purchased with a BBWM)

Special Note regarding ‘81-‘87/‘91 square CUCV military trucks:  The first production runs of these kits were not compatible with CUCV trucks. 

Kits ordered after Sept 15th, 2021 are now compatible with the CUCV style trucks

The BBWM Upgraded Kit (winch line exiting through or under bumper) includes:

 

 

Not included:

  • Winch
  • Winch hardware
  • Winch fairlead

  • Engineered Vintage Shackle Brackets (available separately - recommend ordering non-hardware version as BBWM hardware can mount both)

Installation considerations

Inspect truck frame before installing this kit.  Truck frame should be in good repair before installing.  Frames that have rust holes, been cut, modified, drilled (other than for factory tow hooks or to mount BBWM) or that have any other damage should be professionally inspected and repaired before installation of the Behind Bumper Winch Mount kit.   DO NOT INSTALL THE BBWM KIT ON TRUCKS WITH DAMAGED, CORRODED, BENT, OR HEAVILY MODIFIED FRAMES.  

 

What winches fit?

With the variety of winches available on the market today, note that not all winch combinations may work.  However, rest assured that the BBWM is designed to fit a wide variety of winches.   

Installer should consider how their particular winch will be operated once installed (how to reach winch controls once winch is mounted) and check with their winch manufacturer on capability of their particular winch being mounted and operated upside down.

The BBWM Kit is designed to mount feet down style winches with the common 10” x 4.5” bolt pattern.  For high mount configuration, the winch must fit between / inside frame rails of the truck (GM frame rails of this year are C shaped, with approx 24” between narrowest part, around 28” to inside of each frame rail, and about 4.5” in height.  The low mount configuration allows wider winches to be mounted.  

The BBWM Kit also has provisions to mount the older Badlands short drum winches (6K) with 6.5” x 4.5” pattern and also the WARN competition/short drum winches with the 6” x 4.5” bolt pattern.  

The BBWM is not compatible with feet forward style mounted winches (will NOT fit the WARN 8274, M12000, M15000, M16.5T nor other style winches with feet forward mounts)

FAQs:

What winches fit? 

Please see our list of compatible winches (above)

 

Is drilling required?

We recommend drilling one hole in each frame rail for the the install, to ensure the most secure mount to your truck's frame.  If the standard kit is selected, cutting of the bumper to allow winch line to exit through bumper is required.  Upgraded kit allows for the winch to exit under bumper, but ground clearance is less (due to winch being closer to ground)

 

Will this kit fit 88-91 Suburbans, Crew Cabs, and full-size Blazers / Jimmys? 

Yes

 

Will this kit fit military GM square body trucks (CUCV series)? 

Yes, our kit has been installed and tested on the CUCV Square body trucks (M1008) and also the "blazer" version of the CUCV, the M1009

Our kit fits all variations of GM square body military trucks: the M1010, M1028, M1030/31. 

There is additional cutting and drilling on the military trucks to install this kit (inner front frame reinforcement must be removed as our bracket replaces it)

 

Will the WARN M10K, M12000, M15000, or M16.5ti work with this kit?

Please see our list of compatible winches (above)  Short answer is no

We recommend the WARN VR EVO, WARN ZEON, Smittybilt X20, or the Harbor Freight Badlands if you are wanting to run a 10K or 12K capacity winch

Check out our 'GOAT' front winch bumper if you are looking to run one of these heavy capacity winches on your 81-87/91 GM truck

 

Is this kit compatible with B52 front spring kit?

Yes - additional drilling is required in truck frame.  Additional grade 8 hardware may be required (not included)

 

Is this kit compatible with ORD steering brace kit?

Yes - but this kit replaces the front half of that kit.  (The brace on front side of stock cross-member is replaced)

The product was well better than expected. I have already had to use it a few times and honestly it was well worth the price. They stand behind their product and I recommend them to everyone
