66-77 Bronco Hidden Winch Front Bumper | LowPro | RockSolid Series (PF307)
The 66-77 Bronco Hidden Winch Front Bumper, also called The LowPro, is a favorite among classic bronco owners. This Bronco bumper is made completely of 3/16'' Plate steel and is winch ready. Easy bolt-on installation with no welding or drilling required.*
The RockSolid™ Bumper design makes it difficult for obstacles to trap. It is designed so that your truck slides upwards and onwards over any obstacle rather than catching. This very durable and modern design has multiple built in tow points or add a set of ‘D’ ring tabs for the ultimate tow points.
*This statement applied to the fully Welded edition of our bumper. The other editions require several hours of welding and grinding.
Edition
| Box Kit: Completely disassembled bumper kit shipped in a box. Only recommended for experienced welders/fabricators as it requires several hours of welding and grinding to complete. The lead time for this product is significantly less. (Typically a 3-4 week lead time) |
| Tack Kit: A tack welded kit that arrives in its true form and will require several hours of welding and grinding to complete. It is not a flat kit and will not be more economical when shipping. |
| Welded: Arrives as unfinished raw-steel ready to install. We ALWAYS recommend test fitting the bumper to your truck BEFORE applying paint or powder coat. Once you have successfully mounted the bumper to your truck, it is safe to remove it and apply a finish. |
Add-On's
Push Bar: Add a push bar to your front bumper.
| The Flat Top (No Bar): Just like it sounds. This option means there is no push bar. |
| The Bull Bar: A single low-cut hoop in the center of the bumper made from 2" 0.120 wall round tubing. |
| The Pre-Runner: A taller center hoop with diagonal kicker tubes extending to the outside edges of the bumper. Made from 2" 0.120 wall round tubing and 1 1/4" side braces. |
Adjustable Body Lift: Add an adjustable body lift to your bumper. This system uses pucks to set the bumper at the appropriate location when your truck body is lifted off the frame. See our install guide for more information about how it works.
Suggested winches
The bumper's interior is 7.25" tall and utilizes the standard winch mount bolt pattern of 10" x 4.5". The winches that fit in this bumper are very limited and are a tight fit, but the following we know will fit without issue: Warn M8 and Warn VR Evo*.
Warn M8
Note: The winch pack will need to be relocated to fit in this bumper. We suggest putting the winch pack under the hood to help keep it protected from the elements.
Note: The winch pack and the cover above the cable spool will need to be removed for this to fit in this bumper. It is a tight fit, but should definitely fit. These winches have been successfully installed numerous times in this bumper. We recommend relocating the winch pack under the hood to help protect it from the elements.
Other Winches
The SmittyBilt Gen2 XRC 9.5 or 12k (The XRC Gen3 will not fit) and SmittyBilt X20 Gen2 have not been tested but based on manufacturer specified height, it is POSSIBLY a suitable fit for this bumper. We cannot guarantee the fit of these products in this bumper so please test fit right away in case you need to send anything back.
