Snowmobile rail brace

A rail brace system for use with a monorail of a snowmobile, the rail brace system comprising:

• a first brace having a first end, a second end, a length extending from the first end to the second end, a top side, a bottom side, a height extending from the top side to the bottom side, an inner surface, an outer surface, a width extending between the inner surface and the outer surface, an upper portion extending downward from the top side, and a lower portion extending upward from the bottom side, a first portion of the outer surface is on the upper portion and a second portion of the outer surface is on the lower portion, the inner surface is shaped complementary to a first side of a monorail of a snowmobile, wherein the first brace includes an opening extending through the width, a center of the opening is positioned at least two inches from the second end, the opening is positioned along the length of the first brace to be concentric to a suspension mount hole of the monorail and the outer surface around the opening is configured to provide a mounting surface for a suspension arm of the snowmobile;
• a second brace having a first end, a second end, a length extending from the first end to the second end, a top side, a bottom side, a height extending from the top side to the bottom side, an inner surface, an outer surface, and a width extending between the inner surface and the outer surface, the inner surface is shaped complementary to a second side of the monorail;
• and
• an upper brace connecting the top side of the first brace to the top side of the second brace, and wherein the first brace, the second brace, and the upper brace are a single piece.

A rail brace system for a snowmobile, the rail brace system comprising:

• a monorail including a first side, a second side opposite the first side, and a suspension mount hole extending from the first side to the second side;
• a suspension arm having a first portion and a second portion;
• a first brace having a first end, a second end, a length extending from the first end to the second end, an inner surface complementary to the first side of the monorail, an outer surface, a width extending between the inner surface and the outer surface, and a first opening aligned with the suspension mount hole of the monorail, a center of the first opening is positioned at least two inches from the second end, the outer surface of the first brace forming a first mounting block that is integral to the first brace, the first opening extending through the first mounting block;
• a second brace having a first end, a second end, a length extending from the first end to the second end, an inner surface complementary to the second side of the monorail, an outer surface, a width extending between the inner surface and the outer surface, and a second opening aligned with the suspension mount hole of the monorail, a center of the second opening is positioned at least two inches from the second end, the outer surface of the second brace forming a second mounting block that is integral to the second brace, the second opening extending through the second mounting block;
• and
• a bolt extending through the suspension arm, the opening of the first brace, the suspension mount hole of the monorail, and the second brace, wherein the bolt maintains contact between the first mounting block and the first portion of the suspension arm and maintains contact between the second mounting block and the second portion of the suspension arm.

A method for bracing a monorail of a snowmobile, the method comprising:

• attaching a first brace to a first side of a monorail of a snowmobile, the monorail including the first side, a second side opposite the first side, a front end, a rear end, a length extending from the front end to the rear end, a mounting block attached to the first side of the monorail, and a suspension mount hole extending through the first side, wherein the first brace includes a first opening that is aligned with the suspension mount hole of the monorail, wherein the first brace extends at least two inches from a center of the first opening towards the front end of the monorail;
• removing the mounting block attached to the first side of the monorail before attaching the first brace to the first side of the monorail;
• and
• fastening both the first brace and a suspension arm of the snowmobile to the monorail using the suspension mount hole of the monorail.
