4-Star Structure Means the Safest, Most Durable, and Simply the Best Trailer on the Market

Enclosed Hollow Tube Toprail
Exclusive to 4-Star, the strongest toprail in the industry is fully enclosed, tempered, & extruded as a single piece. This is the only toprail engineered to resist twisting & warping. Each 4-Star toprail is a single piece spanning the trailer’s length. This design eliminates any weak points, ensuring the trailer operates as a cohesive whole, rather than breaking down & pulling apart.

One-Piece Drop Plate
This exclusive piece is another key to the safety, longevity, and durability of 4-Star trailers. It’s tough enough to stop a .45 caliber bullet, and 50% thicker than the multi-piece drops used by competitors. The aluminum alloy plate is 3/16″ thick with integrated gooseneck gussets, eliminating unnecessary welds and opportunity for weakness.

Bottom Rail with Reinforcement
Validated by one of the nation’s leading aerospace consultants, the 4-Star bottom rail effectively distributes stress along the length of the trailer. The hollow, closed design provides incredible, consistent strength without the added weight of a solid bar.

1”x 8” Enclosed Drop Post
Like most 4-Star structural components, this extrusion is enclosed on all sides. This design is far stronger than open C-shaped posts used in other trailers, adding strength in yet another strategic area! The rounded corners face the trailer interior for safety. Minimum 1/8” wall thickness ensures there are no weak areas in this important structural piece.

Crossmember
4-Star crossmembers provide exceptional strength and rigidity to a trailer’s frame, ensuring it can withstand heavy loads without bending or flexing. Its robust design distributes weight evenly, reducing stress points and enhancing structural stability. By preventing sagging and frame distortion, the 4″ I-beam crossmember on 9 5/8′ centers extends the trailer’s longevity, maintaining durability even under demanding conditions.

Bottom Rail/Running Board
This component integrates the bottom rail and running board into a single piece. The running board gains strength as a piece of the structure instead of being welded on. Since the entire piece is a solid extrusion, the running board in turn adds stiffness to the bottom rail. This reduces the twisting and warping of the entire trailer, contributing to the overall durability.

Divider
This structural tube is specifically designed with the safety of your horses in mind. A divider is designed to safely separate horses, preventing them from shifting, crowding, or injuring each other during transport. It helps maintain balance by providing individual space, reducing stress and the risk of falls. The divider also minimizes sudden movements that could destabilize the trailer, ensuring a smoother, safer ride for both the horses and the driver.
