Electrostatic Powder Coating - Our preferred finish due to it's durable surface... it is an electrostatically applied plastic coating infiltrating the substrate of the metal providing a distinctive finished look. We have found this surface finish to be far superior to any painted finish. This polyester powder coating material can be repaired easily... It will not pull back significantly if welding is necessary nor will it flame up in the welding process. We have found that it can be spread with a trowel when it is hot and blended easily. To make the repair look natural, feather the area when cool with sandpaper and paint with Krylons new fusion paint. It is made to paint polyester plastics thus providing a coating like the type of powdercoat we use. Our new awareness of the qualities of this powder coat and the fact that paint and powder coat now costs about the same, has led us to drop paint from our options list. Powder coating includes sandblasting, sanding, powder primer coat and a powder finish coat in a variety of colors. Black is the most popular, but a variety of other colors are available.

Phosphoric Acid Coating - Frames that our customers would rather finish themselves are sprayed with a metal prep solution to keep the frame from surface rusting until it is sandblasted and finished. This coating forms a white powder on the surface easily removable with soap and water. It is highly recommended that the chassis be sandblasted and finished as soon as possible.

Un-Finished - As the title implies, completely unfinished


Expanding Foam - Our Preferred choice is relatively new to the market.. This foam is expanding closed cell, water proof foam which sticks like glue to all surfaces when hardened. It is not a sponge and will not absorb water. Also it does not allow anything to infiltrate the interior of the chassis. The expanding foam is forced into one end of the open tubing and allowed to ooze out of the other end to assure a complete fill. Once fully expanded the over fill is cut away and the fill holes are filled with plastic caps. This foam application does two things to the structure. First it makes for an impenetrable water seal and secondly sound dampens the frame. You may think this a minor point but in fact the frame does resonate and amplify the vibrations caused by road conditions and those passed along by the drive train. Foam filling quiets the ride appreciably. About 90% of all the frames made to date are foam filled.

Front Suspension

Front Tube Shock Conversion Kit

This kit replaces the standard lower shock mount brackets, the ones that look like dog bones, with new brackets. The new brackets allow the use of the Sensatrac shock absorbers, which has pin type ends. Orientation of the new bracket is essential in the operation of the system and specifically the shock absorber. This kit is recommended as a complement to either of our rear shock conversion kits.

Rear Suspension

Rear Tube Shock Conversion Kit

The rear tube shock conversion kit consists of the L shaped brackets which attach to the original lever shock mount. Due to the high moment arm stresses created by these brackets, a stiffener support was created to connect across from the left shock mount to the right which significantly strengthens and supports the shock mounting plates. Also supplied are the lower shock mounting plates which replace the original U-bolt mounting plates and create the lower mounting point for the Tube Shock as well as adding a new tie down point for transporting the car. Black Semi-Gloss Powder Coat for Rust Resistance. Please let us know if you have a TR-2 or Early TR-3 as we need to provide a special version of the kit for you.

If you are using any of the above mentioned carburetor setups with either the stock, Pierce Cannon or Goodparts manifolds, then these kits will make your life so much simpler. It eliminates the bell crank system used in the stock carburetor setups and replaces it with a modern, infinitely adjustable, aircraft quality, push pull cable system.

RATCO's approach is to simplify the entire connection between the accelerator pedal and the throttle connection at the carburetor with a cable instead of a bellcrank. In the process we have eliminated that cumbersome bellcrank linkage and have added adjustability which allows foot pedal height adjustment, full open throttle settings and free play adjustment. All this adds up to a smoother and more accurate linkage for the street rider and track racer alike.

This system replaces the bell crank assembly at the carburetor with a push/pull aircraft cable assembly connected to the lever at the passenger side firewall and a simple bracket at the carburetor. Now Weber owners can get full throttle acceleration, which was impossible with the stock linkage. Installers get to choose the location of the carburetor bracket, which is most convenient for them and all users get smooth accurate response to pedal pressure.

All hardware needed is included and complete instructions come with the kit or can be downloaded from this web site. All parts are powder coated and all hardware is nickel-plated. Installation takes about 1 hour and requires drilling holes in the firewall to mount the bracket.

Emergency Hood Release Kit

You may not have experienced it yet, and we hope you never do, but one day you're going to pull the hood release handle and you're going to feel the cable slip from it's clamp, or snap entirely. Due to the fact that the locking mechanism is located on the firewall, it is all but impossible to reach. This simple and inexpensive kit allows you to have a secondary method of opening the hood in case of such an emergency. Many of our customers tell us they like it so much they often use it instead of the original. It is also more convenient because it is accessible from the passenger side which is where the secondary latch is located, so it saves some walking around the car.

Our kit is unique in that it uses the existing hole in the locking mechanism, rather than requiring you to drill a new hole. We always prefer to minimize permanent changes in favor of reversible changes. The installation is extremely simple and requires only a single 1/8" hole in the firewall to allow the control rod to enter the passenger compartment. Please review the photo below.
