4X4LABS expedition bumpers offer the most protection, highest clearance and have more available options than anything else on the market by far. We have been building this style of bumper for over 10 years. Our design has evolved into a simple, modular and customizable system. Every part carefully engineered delivers performance, function and durability forever. The design is simple, refined and beautiful following the body lines and curves of your 4runner. 

  • High clearance bumper profile and skid plate style side protection 
  • Towing receiver, two recovery points and hi-lift holes built in 
  • Swing outs accept a variety of attachments can be switched out or removed 
  • Heavy duty spindles and latch assure a rattle free bumper forever 

Every detail of 4x4labs bumper systems have been engineered and designed for use in demanding off road environments. The bumper system swing arms will accept a variety of different bolt-on attachments that can be ordered separately or added later. 

The Main Shell is made from 3/16” cold rolled steel, our own bull nose bending dies create the high clearance 4x4labs bumper profile. 

Side protection for the rear overhang are high clearance, CNC cut and formed steel plate style skid surfaces wrapped under the body. 

The towing cross member, two recovery points and related tow parts are built into the bumper from square tube frame cross members and high clearance tow receiver tubes recessed into the main shell of the bumper. It is stronger than the stock towing accessory. 

Modular Swing Outs - Our clever swing out solution is the key to the functionality of this system. Our own heavy duty spindles are welded through the main shell of the bumper for optimum strength. Sleeved swing arms give you the option of which attachments to carry or leave at home. Single swing arms are not recommended for the 4th gen due to the curve of the rear hatch. Double swing arms are half width and latch in the center. Spare tire placement is usually on the driver side unless ordered custom.

Cutting and grinding required for installation. Refer to the installation document for clarification.



This is one of the most difficult bumpers we offer in kit form. We use a purpose built jig to build it in our shop. You must be an accomplished fabricator/welder to build this bumper on your vehicle.
