GFRP 2026 Assault Sprint Car Kit

2026 Assault Rubber Tire Dirt Oval Kit. Fully metric.

Manual available by clicking HERE.

The 2026 Assault features a newly designed chassis plate for optional stiffness with the new three post molded cage.

• A laid in front shock tower paired with small bore bladder shocks now comes stock in the kit to compliment the new cage and wing mount.
• The 26 Assault has kept the dual bell crank steering platform, but has updated to 70mm molded arms and a new style caster block to allow a better steering response.
• A droop bulkhead comes stock in the kit to allow for optional droop plate.
• Adjustability through the rear end has broadened completely.
• The rear shock tower has doubled its options for mounting the rear shocks to allow for more tuning.
• The 2025 Layback transmission with its 39T idler gear appropriates less wear and more smooth power delivery; the diff height adjusters pair with the new plunge rear axles to change the geometry of the dogbones.
• The transmission changes are integrated with new 0/3 toe blocks, a wider outer rear adjustable arm, and a lighter rear camber link mount to adjust for more track conditions.
• The kit also features the GFRP springs and lowered spring cups to enable a better baseline for the car.
