Top 6 Replacement Leaf Spring Packs for Horse Trailers in Canada - 2026

Dexter's 7-Leaf Double Eye Spring Pack (3500 lb) is best-in-class for replacement leaf spring packs for horse trailers because its extra leaf provides improved load distribution and a smoother, more forgiving ride under varied trailer loads. Compared with the 6-leaf alternatives in this list, the seven-leaf layout typically yields longer fatigue life and reduced long-term replacement cost at a modest upfront premium, making it the preferred choice when durability and ride comfort for valuable livestock are priorities.

Lippert's 4-leaf double-eye 3500 lb spring is a market leader thanks to its widespread OEM adoption, easy sourcing, and typically lower upfront cost—making replacements fast and economical for most horse trailer owners. Relative to heavier multi-leaf packs like Dexter's 7-leaf or a 6-leaf assembly, the Lippert unit is lighter and simpler to install but trades some progressive load handling for affordability and availability.

Southwest Wheel's 5-leaf slipper 3500 lb pack offers the compact slipper-style mounting many trailer builders prefer, with a balanced ride and corrosion-resistant finishes aimed at longevity in road and barn environments. It sits between the firmer 4-leaf and heavier 6–7-leaf designs in ride characteristics, and is often a more budget-friendly, easy-to-fit alternative to premium imported packs while still providing solid load support for typical horse trailer use.

AL-KO's 5-leaf double-eye 4400 lb pack brings a higher 4400 lb rating and European engineering precision, making it the top choice when a higher GVWR or heavier trailer configuration is required. Although typically priced above the 3500 lb U.S. packs on this list, its increased capacity can eliminate the need for other upgrades and deliver longer service life under heavier loads, which can be a cost-effective investment for owners upgrading or commercial operators.

Trailer Leaf Spring Works' 6-Leaf Double Eye Spring (5200 lb) is the market leader for owners who need higher payload capacity for horse trailers, offering a significantly higher 5200 lb rating than the 3500 lb options. As an aftermarket-focused product it delivers thicker leaves and competitive pricing for heavier-duty applications, trading a firmer ride for greater GVWR capability and often a lower immediate purchase cost compared with OEM-branded 3500 lb packs.

Rockwell American's 6-Leaf Double Eye Spring Pack (3500 lb) is a reliable OEM-equivalent replacement that combines consistent manufacturing quality with wide parts availability for horse trailer repairs. It matches the 3500 lb rating of the Dexter pack but uses a six-leaf configuration that usually produces a slightly firmer ride and lower street price, presenting a practical, cost-effective middle ground between the higher-capacity Trailer Leaf Spring Works unit and the smoother seven-leaf Dexter option.
