Precision Fitment That Solves Clearance Issues Fast

The Wehrli 100453 Bumper Spacer Kit is engineered for proper fitment and long-term durability on 2015–2019 GM 2500HD and 3500HD trucks. Each kit moves the front bumper forward by 3/8 of an inch using precision CNC-machined billet aluminum spacers that maintain full mounting surface area for strength and support. This slight shift in bumper placement opens up the front wheel wells, allowing for taller and wider tire setups with more aggressive negative offsets, all without needing to trim or modify factory body panels. The spacers are finished in a durable flat black powder coat that provides corrosion resistance while blending into the stock bumper components for a factory-style appearance. Installation is straightforward and requires only basic hand tools, making it an ideal solution for DIY enthusiasts or professional builders. Because the kit is tailored specifically for GM HD trucks, everything lines up exactly how it should with no guesswork or awkward gaps. Whether you’re prepping for larger wheels or just solving fitment headaches, this kit delivers a clean and effective result.
