C4 Fabrication

About C4 Fabrication

C4 Fabrication is an Arizona shop led by founder Caleb Rupp, who brings more than 15 years in off-road manufacturing. Everything is designed and built at the company's Chandler facility.

The focus is narrow on purpose: Toyota and Lexus. C4 is best known for its Lo-Pro, Hybrid, Overland and Rock Runner bumper series, full skid packages, rock sliders and 4Runner MOLLE storage. The pitch is consistent fit and armor that doesn't look like an afterthought.

What we carry from C4 Fabrication

We stock C4 front bumpers and rear bumpers, including Lo-Pro and Hybrid models plus high-clearance additions, bumper caps and winch relocation brackets. There are also rock sliders, skid plates (front, differential, fuel tank and full sets), high-clearance fender liners and body mount relocation kits.

For storage, C4's MOLLE panels, shelves and engine-bay accessory trays round things out. Fitment covers the Toyota Tacoma (2nd and 3rd gen), Toyota 4Runner (4th, 5th and 6th gen), Tundra, Land Cruiser 250 and Lexus GX.

How to choose

Generation is everything with C4. The 4Runner alone splits into 4th gen (2003–2009), 5th gen (2010–2024) and 6th gen (2025+), and parts don't cross over.

• Match the part to your exact generation and model years.
• Want more approach angle from a Lo-Pro bumper? Pair it with the high-clearance additions.
• Bumpers usually ship by truck freight. Use a street address that can take a freight delivery; PO boxes are out.

Lead times & shipping

Plan around production. Our current estimates for C4: bumpers about 8–14 weeks depending on the model, rock sliders about 8–10 weeks, skid plates about 2 weeks, and accessories often about 2 weeks. These are estimates and they move with C4's production schedule, so check our current lead times page or call before you plan a trip around delivery.

C4 Fabrication warranty

C4 covers manufacturing defects in welds, hardware and mechanical parts for 1 year from the ship date, for the original owner. Powder coat isn't covered, and neither are trail damage, rust, normal wear or parts that were modified. C4 decides whether to send replacement parts or issue a full or partial refund.
