The Hurricane 427 Roadster frame is a custom built ladder style frame designed to
provide excellent torsional rigidity along with precision hard mounts for critical
safety components of the kit. The main rails are extremely strong 2" X 4" steel tubes with a wall thickness
of 3/16" (.180). All other frame steel is .120 wall tubing.
Torsional Rigidity
We achieve a high level of torsional rigidity by utilizing a
large X brace in the center section of the frame along with diagonal bracing to the rear
riser section of the frame. A more rigid frame reduces chassis flex which maintains
correct suspension geometry under hard cornering.
Critical Hard Mounting Points
We have engineered hard mount points into the frame for all hinges and latches, seat
belts, seats, emergency brake and roll bar.
An added level of safety is achieved by mounting critical components directly to
the frame using gusseted brakcets rather than mounting them to the fiberglass or to aluminum.
Round Tube Cross Braces
Traditional round tube cross braces are used between the front suspension towers to prevent flexing
during hard cornering.
Reinforcing in Critical areas
The frame is reinforced in areas prone to stress such as near the motor mounts and over the rear axle.
Double Dropped Steel Foot Boxes
The frame includes a double dropped foot-box with 1/8" steel plate floor pans. The deeper foot-boxes provide
additional foot room (there is acutally enough room to rest your foot under the hanging pedals on long drives).
The steel floors provide an added level of safety from dangerous floor penetration from road debris.
Jig Built by Certified Welders
Each frame is built on a custom chassis jig to ensure consistent placement of critical mounting points
every time. All of our welding is done by certified welders that we employ.
