Axle change from drop to straight. All Stallion models are standard with drop leaf spring axle(s). If you desire straight "no drop" leaf spring axle (s), choose this option. This will raise the trailer floor deck height 3-1/2"- 4" higher off the ground than the standard drop leaf spring axle. Add to cart and change quantity to match number of axles on the trailer you are ordering. Price is per each axle. Example: Single axle=1, Tandem axle= 2.
