The 2026 ProTruck Rules have been posted. Every year there are revisions. The series or competitors propose new or updated rule changes. Some are approved and some are not.

This year the series proposed eliminating 4bbl carburetors from competition except for claimer motors. Competitors pushed back and were not ready to give up their four barrel carbs. The competitors, led by the 94 and 47 teams tested. They were instrumental in ciming up with some rule adjustments.

Claimer motors are still exempt from carburetor rules however competitors with 602 Crate Motors may run a 650 4bbl carburetor provided they take their truck to the Chassis Dyno before racing. When they do race, they will need the dyno sheet. Having pretested at the dyno does not preclude the truck from post-race testing.

The series is attempting a cost saving measure was put into place. For 2026 most teams may use a spec front shock and receive a 100 lb. weight break. These shocks are available for under $150.00.

This type of racing has always utilized stock type front snouts. Unfortunately, these snouts are getting scarce. Companies like Howe racing, Johnson Chassis and Hamms welding have recognized this problem. They hand craft some fine replacement snouts that often turn out cheaper than prepping the stock ones. Most are lighter than the stock ones. Those replacements are legal but now have appropriate weight adjustments required.

Some pretty impressive new chassis have found their way to the series in recent years. Rules governing the set back, height and construction were reemphasized.

There were some body changes for 2026. Often teams fight overheating issues. Louvers are now allowed on the hood that may help that issue. By team request roof rails are now allowed. Spoilers have some new placement specifications and a new 8 inch Five Star Spoiler has been made legal. The new spoiler makes the Thompson and New Hampshire races especially interesting.

The new rules are posted and 2026 is officially underway.

2026 Starts with the Annual Rules Meeting

The 2026 ProTruck Season is fast approaching. When the season ends, teams immediately start prepping their trucks for the next year. The first step is the annual rules meeting. There will ber a grace period where teams may feedback or offer adjustments to the new changes. It will be tough to get an adjustment once the changes are published on January 1 2026.

This year’s event will be held in Connecticut and hosted by Mike Leone, owner of the 1NE ProTruck team.

Some of the major 2026 Proposed Rule include,

• All weights being increased 50 lbs. except Seekonk Metric or S Chassis
• Snouts-Tubular in appearance will have a 30 lab per frame rail weight increase. The series is based off Metric Snouts.
• Enforcement of the rules governing setback and height of the main cage will be emphasized.
• Hood Louvers will be allowed to aide in cooling and handling.
• Roof Rails will be allowed
• The 10 inch rear spoiler can run Triangular side panels
• An optional 8 inch Five Star Rear Spoiler is now available
• The claimer engine program will continue to expand with motors expected to be purchased directly from the series soon.
• Engine sealing may be a process performed directly through the series in the near future. As for right now the Engine Alliance seals are preferred.
• All engines except claimers will be resuired to run the 4412 2bbl
• Seekonk Sport Trucks may convert to 3 points.
• If teams other than Seekonk Metric or Sport Truck opt for the Afco 1475, or 1474-6 shock package on the front, they will receive a 100 lb weight break. Otherwide the shock rule is unchanged.

As always, the teams discuss the 2026 schedule. A few more events could be added. The addition of Wiscasset is a pleasant surprise. The Championship most likely being decided at Lee USA’s Oktoberfest. The series is awaiting a SpeedBowl date.

All of the points series are expected back in 2026 including the $10,000 ProTruk Challenge, the Super Speedway Challenge, and the Short Track Challenge. The next event for the ProTruck teams is the 2025 Banquet where the series will hand out over $18,000 in awards. That date is expected next week.
