Pre-Engineered Bolt-In Rollcage System for Adding Chassis Stiffness to Your Muscle Car
The TigerCage is specifically designed to interface with the structural strength points of the oem unibody ( or frame ) to tie them together & increase torsional rigidity within the chassis. The main hoop of the TigerCage connects to the area behind the front seats where the rocker boxes intersect the floorboard. The ''back bars'' run from the top corners of the main hoop to the rear package tray (which is an important structural reinforcement in most cars) and is secured in both the horizontal plane and the vertical plane to optimize rigidity. The mating trunk bars join with the back bars underneath the package tray and are fastened with reinforced brackets to the rear framerail to complete the base structure. The optional door bars connect the main hoop to the toeboard/floorboard/rockerbox/A-pillar area at the base of the A-pillar. The complete TigerCage structure lends a huge amount of structural rigidity to a unibody or a full frame vehicle. Not only does this increased rigidity allow extra crash protection, it will allow the vehicles suspension to react more predictably to driver input. Although every effort is made to optimize the crash protection benefits, please be aware that any crash protection that a TigerCage [or any other rollcage] may offer is strictly coincidental. It is impossible to guarantee any specific level of protection in a crash situation.
Minimal disassembly of your interior
Pre-engineered mounting locations designed to interface with structural strength point of car.
No need to locate and schedule a competent welder
Pre-determined installation time avoids uncertainly of custom fabrication time
Integrity of components and fasteners
All components and fasteners can be tested and certified as appropriate for the application.
Welded joints are harder to test and certify. This is why bridges, buildings, and airplanes are bolted together instead of welded together.
The TigerCage offers the unique advantage of being able to un-bolt the unit if the car should be sold or you want to restore it to original configuration.
Can the TigerCage be welded in?
Yes, the TigerCage tubing, mounting bracketry and TigerClamp assemblies are all made from 304 grade stainless, which is easily weldable.
Why would I choose a bolt in cage system when weld-in kits are so much cheaper?
IF you have considerable welding skills, IF you are a competent chassis designer and fabricator, IF you have no problem removing your interior, and IF you have the extra time to devote to such a project, then a weld-in cage might be the appropriate choice for you. If you lack any of these resources then the bolt-in TigerCage system may be a very viable consideration.
Is the TigerCage certified? (NHRA, SCCA, SFI, etc...)
Although certification is planned and in progress, the TigerCage is NOT currently certified for racing in NHRA or SCCA sanctioning bodies but is pending. However, Certification has been given to the Tiger Cage for use in competition up to 175mph by the ECTA land speed racing.
NOTE: The primary function of the TigerCage is chassis stiffening. Any safety protection is strictly coincidental.
Each unit is specifically designed for the car that it is intended for...no fabrication needed
Designed to work with oem interior, door panel, and seat components
The TigerCage fits closely to headliner and interior panels to minimize passenger intrusion
How Strong Is It?
Connects to structural strength points of the vehicle in the floorboard, A-pillar, toe board, rocker panel, B-pillar, package tray and frame rail areas - avoids the need to permanently alter your musclecar with weld-in subframe connectors.
Constructed of .120'' wall 304L grade stainless tubing - stronger than .120'' wall mild steel that is typically specified in sanctioning body rulebooks.
Patented TigerClamps and bungs are made of investment cast 304 stainless steel. The tabs are .375'' lasercut plate stainless.
The TigerClamp has been tested to resist more than 450 ft. lbs of rotational force against the tubing. This means that it takes over 450 ft lbs of force to rotate the TigerClamp around the axis of the tubing. Most small block Chevy's don't make that much torque!
The TigerClamp system will be available in bulk quantities to suspension manufacturers who wish to develop their own applications
Clamps and Bungs
304 Stainless tubing has a tensile strength of 73,200 psi. This is compared to 1020 mild steel at 63,000 psi and 4130 chrome moly at 106,000psi.
Most current sanctioning body specs require a 1.625'' OD .120'' wall mild steel which would have a rating of 35,700 lbs. TigerCage uses a 1.75'' OD; .095'' wall 304 stainless tubing that has a load rating of 36,150, and a 1.5'' OD; .120'' wall [door bars] that has a load rating of 38,000 lbs.
As you can see, TigerCage's stainless tubing has a slightly higher rating than the typical mild steel product.
The TigerClamp and bung components are made from a 304 cast stainless material by an AMERICAN casting foundry.
Air Ride has tested the clamp collars to resist over 450 lb. Ft. of rotational torque. They have tested the pivot connection to resist over 250 lb. Ft. of torque.
In car bracketry is all 304 3/16'' thick stainless. TigerCage uses 1020 steel backing plates underneath the car to evenly distribute the load through the oem floorpans and pillars.
The 1/2-20 thread pivot bolts are rated at 180,000psi tensile strength, which would equal a direct load rating of 25,500 lbs.
The 3/8-24 clamp collar bolts are also rated at 180,000psi tensile strength, which would equal a direct load rating of 15,800 lbs. each.
The fasteners used to attach the bracketry to the vehicle are grade 8 or better, rated at least to 150,000psi, which would provide a direct load rating of approx. 11,600 lbs each.
