Tire clearance and modular upgrades
A modular rear fender system lets you start with the basic inner fenders and add optional pieces later as tire needs change. Larger tires push the wheel further out, which can rub the inner fender edge or the body during articulation. Before choosing a tire size, check clearance at full steering lock and on a compressed suspension so you know where rubbing starts.
Inner fenders work alongside the outer fender and the wheel opening, so changes to one part can affect how the others sit. Look for even gaps around the liner, and check that wiring, brake lines and fuel lines are routed clear of the fender before driving. Keep the wheel well free of mud packed behind the liner. Re-check fasteners after the first few trail runs, since rough ground loosens clips and bolts.
- Check tire rub at full steering lock
- Inspect liner clips after rough trail use
