In response to these conditions, Hydralift has introduced a new dual cam lock system, enhancing stability and safety on the road.

Hydralift’s new dual cam lock system is now standard on all HL4288 standard lifts manufactured after M0903677 (2023). Key improvements include:
✅ Dual cam lock design – Provides an extra layer of security
✅ Redesigned lock seat – Reduces the risk of quick recoil
✅ Elongated locking pin – Improves durability and stability

For Existing Hydralift Owners (M0902700 – M0903677) 

If you own a Hydralift built between M0902700 – M0903677, a DIY upgrade kit is available to add the newer style lock arm with a second cam.

🔧 Note: This installation requires drilling and tapping.
