1/87 scale Lowboy booster set

This Promotex kit delivers two Lowboy Tri-Axle Booster units with integrated rear axles in 1/87 HO scale. It is aimed at adult collectors and hobbyists who build accurate heavy-haul dioramas. Each set arrives in the manufacturer's original unopened packaging and is an officially licensed product. Some simple assembly is required before display.

Upgrade from basic trailer kits

The integrated rear axle and true-to-scale detail replace simpler single-axle trailer models that lack the correct wheel count and booster geometry. The jump is worth it when your layout demands authentic lowboy proportions for oversize loads. Builders who need only a single booster or a different axle configuration will not use the second set.

Capacity and headroom

Each booster measures approximately 3 inches long and each wheel is approximately .5 inches in diameter, matching HO rolling stock dimensions. The four included wheel sets equip both boosters for immediate consist building. The plastic construction limits weight-bearing capacity, so the models are intended for static display rather than powered operation.
