Trailer for ATV & QUAD  : All Glass Fibre Composite

Since April 1, 2021, Transform-Plus Inc. has taken over the production and marketing of the RSK trailer under the new name Trailer RSK-ULTRA.

Misters Germain Bélanger, an expert engineer in composite materials, and Alain Ferland, well known in the hunting industry, entrusted their creation to Transform-Plus for its quality of execution and its experience in the field of fibreglass.


The RSK-I and RSK-II models were the first developments of the product. Today, the techniques developed by Transform-Plus allow a perfectly controlled manufacturing of the product without changing the appearance or risking delamination, hence the new name: Trailer RSK-ULTRA.

This new version of the trailer, «RSK-ULTRA», is characterized by technical criteria and innovative elements in terms of both aesthetics and functionality:
