The single biggest reason to buy is its claimed OEM-quality construction and matching dimensions, which mean a near-direct fit for the listed LT-F400 and LT-A400 variants and reduce the time and effort spent troubleshooting carb fitment.

Who It's For

This carburetor is for Suzuki Eiger 400 owners who need a practical replacement for models listed from 2002 through 2007, including LT-F400 2x4 and 4x4 and LT-A400 2x4 and 4x4 variants. It suits DIY mechanics and repair shops that prioritize an OEM-style part to restore fuel flow and engine response without aftermarket tuning.
