Definition: Vehicles built to appear as full-sized two-wheel-drive utility type vehicles utilizing a Stewart & Stewart Development, Inc. (SSRD) chassis and suspension, SSRD production appearing bodies, various other mandated parts, and an engine of the same manufacturer represented by the body. All body panels are a mandated part, as approved by PRO. This class will be limited to small block V8s. Maximum engine compression ratio is limited to 9.5:1. Engine specifications are noted in the PRO appendix. Please contact PRO for all current updates to the appendix.

This is a limited class and all limited or mandated components must be built and/or supplied by SSRD. All vehicle components are subject to being specified to a particular manufacturer. When a component is stated as mandated, it will be specified by PRO to all competitors.

It is the responsibility of competitors to acquire the most current list of mandated and specified parts for the Protruck class from PRO at (619) 390-6252 or by fax to (619) 390-6470.

Each entrant expressly agrees that by entering the Protruck class, he/she agrees to be bound by all decisions, rules, regulations, and specifications of the Protruck class, including all procedures provided for in these rules. In addition, the entrant, driver(s), owner(s), sponsor(s), and all team members agree to be bound by and abide by the decisions of PRO and its officials.

Each Protruck vehicle will be issued one (1) Protruck Vehicle Log Book for each chassis. The PRO Technical Inspector will hold the log book, and update it at each event following the pre- and post-race technical inspections. Should major repairs include the chassis or other mandated parts, the PRO Technical Inspector must be notified and note these repairs in the vehicle's Log Book.

Pre-event PRO Tech is Mandatory. Post-event Tech is mandatory. The PRO Technical Inspector will/may inspect vehicles prior to, during, and/or after each event. The PRO Technical Inspector and/or PRO has the right to test and/or verify any part used on a Protruck vehicle at any time. Failure to comply could result in disallowing a vehicle to compete, disqualification, and/or penalties.

If the PRO Technical Inspector determines prior to the event that a vehicle does not meet the Protruck class specifications, the vehicle may not be allowed to compete. If a vehicle with a discrepancy is allowed to compete, the competitor will be given a written notice to comply and must make the changes, or the vehicle will not be permitted to compete in the next event.

If the PRO Technical Inspector determines during inspection after an event that a vehicle does not meet the Protruck class specifications, PRO has the right to penalize and/or disqualify the competitor. It will be the responsibility of the competitor to comply with the PRO Rules and to make the necessary changes prior to the next event.

The PRO Technical Inspector and/or PRO has the right to impound any vehicle or confiscate any part used on any vehicle that competed in the Protruck class that fails to meet Protruck class specifications, failure to comply could result in disqualification and/or penalties.

If the conduct of a competitor, owner, sponsor, or crew member, prior to, during, and/or after an event, is deemed detrimental to the sport of off-road racing and/or the Protruck class, as determined by PRO, or if the vehicle does not appropriately represent Protruck racing, as determined by PRO, the competitor and/or vehicle will not be allowed to compete, or will be disqualified, penalized, and/or banned from future events.

PRO reserves the right to amend these rules and regulations for the Protruck class in its sole and absolute discretion.

If the following rules do not state that you can use it, change it, or modify it, then you cannot.

Entrants in this class shall comply with all applicable competition regulations.

Each Protruck must utilize the engine and body combination as determined by PRO. This is a limited class and all specified parts must remain as delivered by chassis manufacturer except for those modifications allowed herein.
