Maintaining a Harley-Davidson motorcycle requires precision, and one common challenge riders face is accessing the oil filter during routine changes. Oil filter relocation kits solve this problem by repositioning the filter to a more accessible location while improving engine efficiency. With multiple options available, choosing the right kit can significantly impact maintenance ease and long-term performance. This guide compares top-rated Harley Davidson oil filter relocation kits, evaluates their features, and provides actionable insights to help riders make informed decisions.
Why Consider an Oil Filter Relocation Kit?
Harley engines, particularly in touring models like the Road King or Street Glide, often position the oil filter in tight spaces. This design forces riders to dismantle components like exhaust pipes or primary covers during oil changes—a time-consuming and frustrating process. Relocation kits simplify maintenance by:
– Improving access for faster, cleaner oil changes.
– Reducing spill risks with strategic placement.
– Enhancing cooling through optimized oil flow (supported by SAE International studies).
For riders prioritizing convenience and engine longevity, these kits are a worthwhile investment.

Installation Tips & Maintenance Best Practices
- Pre-installation Prep: Drain the oil completely and clean the mounting area to avoid debris ingress. Use thread locker on fittings to prevent vibrations from loosening connections over time.
- Post-installation Check: Start the engine and inspect for leaks at idle. Monitor oil pressure gauges (if equipped) for irregularities during initial rides.
- Routine Maintenance: Replace relocation kit hoses every 25,000 miles or per manufacturer guidelines to ensure longevity.
