XB4 ‘25 A Block 7075

Made out of 7075-T651, this is a billet A Block for the XB4 ‘25 Car. It’s a replacement part that offers superior strength to the stock component and is the wide block that comes stock with the car.

Note it can be used with the 24 Chassis with slight bumper modification. We recommend running a piece of chassis tape up and in between the bumper and gearbox which will cover the bottom of the chassis on the 24 car only.
