Sprint Car Components

Titanium Sprint Car & Midget Components

People often ask, "Do you manufacture parts other than fasteners?" The answer is YES. Our engineering background and interest in motorsports has led to the development of light weight, durable, drive train and suspension components. A large portion of our business is manufacturing customer specific parts rather than off the shelf "Standard Parts". Many of these engineering and manufacturing services are performed under proprietary agreements with our customers. Quality begins with design and carries through final inspection, and field testing. Mettec engineers are members of ASME, and have also served on numerous code committees. Our products will keep you on the leading edge of material science and process applications.

Titanium King Pins

Mettec's titanium king pins are 40 grams lighter than our nearest steel competitor. We designed the king pins to utilize heat treated titanium. Higher shear strength makes a longer lasting and safer king pin. Each king pin has a top flange and a screw in cap on the bottom. Race track proven performance speaks for itself.

Titanium Drive Shafts

Mettec titanium drive shafts are designed for long life. Everything from shape to final surface finishing is aimed at creating a strong and durable shaft. Mettec provides five (5) shaft lengths. The 10 spline end is 4 inches long so it can be trimmed up to 2 inches. The remaining 2 inches can engage into either an external 10-10 coupler or the internal coupler of the rear end.

Titanium and Steel Torsion Stops

Mettec stop arms are made in titanium and steel. Mettec titanium arm weighs .40 Lbs. which is over ½ pound lighter than any other steel stop on the market today. The steel arm weighs .82 Lbs. which is a 1/10 of a pound lighter than our nearest competitor. Mettec steel arms are gold-zinc plated for a professional look and rust protection. Manufacturing controls are the same for both steel and titanium. Any time Mettec offers alloys other than titanium, the part is equal in quality to our titanium part. Steel material is less expensive to buy and easier to machine, so the price is lower. Mettec assures you, if a part is made by Mettec from steel or titanium, the parts are equal in quality.

Mettec titanium torsion bar stops are forged from billet bar stock. Our new alloy, developed by Pratt & Whitney, provides an Ultimate Tensile Strength of 180,000 psi which is superior to conventional aerospace titanium 6-4 (UTS 140,000 psi). Our stops are superior to steel in strength and are half the weight. We offer two sizes of stops. Titanium bolts are used for the pinch bolt and adjuster bolt. We also supply a high quality aluminum jam-nut to complete the assembly.

Titanium Torsion Stop Bolts

As with all our bolts these have rolled threads to provide a long lasting thread that won't gall as easily. Mettec recommends a MOLY grease be applied to the threads before each race. This will give maximum life to your titanium stop adjuster bolts.
