How to Measure

To ensure proper fit and performance, we have designed several measuring sheets depending on your application. These drawings will guide you to get it right the first time.

To measure cars and trucks properly, place two safety stands under the differential housing tubes to support vehicle high enough to maneuver under and measure easily. Measuring the overall length correctly is very important.

  • Step 1. Pick the Diagram that best suits your application. MEASURE EXACTLY as shown and note your answers to use on the Quote page. Diagram "1" and Diagram "2" are used MOST OFTEN for Race Cars and Street Rods.

  • Step 2. Requires a tape measure. Remember always measure your vehicle with the rear tires on the ground OR the rear end on 2 safety stands. It is important to have the suspension in this position to measure correctly. DO NOT MEASURE with the suspension hanging. If measuring 4x4 trucks, you must have both the front and rear tires on the ground or the axles supported on safety stands.

  • Step 3. Call 209-538-8956 for measuring questions.
