BulletProof Hitches 2.5″ Shank — 22,000 Lbs Rated
This 2.5″ weight distribution shank is designed for 2.5″ receivers and fits most weight distribution systems. It excels for lifted or modified vehicles, offering a longer drop and bidirectional functionality in drop and rise positions. Seven ride height options enable precise alignment for level towing, helping to keep tongue weight balanced and the trailer stable. Best for heavy-duty setups with custom suspension or larger tires. A potential limitation is the need for a compatible head assembly and proper hole alignment to achieve the desired height.
Who this is best for: Owners with 2.5″ receivers, heavier trailers, or modified suspensions seeking maximum adjustability and corrosion resistance.

This 2″ shank is compatible with most weight distribution systems and is suitable for lifted or modified vehicles that require a longer drop. It features five ride heights to fine-tune head height and achieve level towing. Best for users who primarily operate 2″ receivers but still want robust corrosion resistance. A trade-off is that it does not directly fit 2.5″ receivers, so choose this if your hitch system is 2″ standard.

Buying Guide: Key Considerations for 2.5-Inch Shank Weight Distribution Hitches
- Weight rating and tongue weight: Ensure the shank supports the trailer’s GTW and tongue weight within the hitch system’s limits. Higher ratings are often needed for larger trailers or lifted vehicles.
- Drop and rise range: Look for multiple ride heights or large rise values to achieve level towing on taller vehicles or with lifted suspensions.
- Receiver compatibility: The 2.5″ shank should match your hitch receiver size; consider whether you also need a 2″ shank for mixed-use setups.
- Head height adjustability: Multiple holes and precise increment spacing help dial in tongue weight distribution accurately.
- Corrosion resistance: Powder-coated or corrosion-resistant finishes extend life in harsh environments and with frequent hitching/unhitching.
- Compatibility with existing components: If you already own a weight distribution head, ensure the shank is compatible with its mounting pattern and holes.
