HOW TO'S   WHAT IF'S
What you need to know for your VW Torsion Bars

Sway-A-Way has greatly expanded the Tech Room. Customers can find updated technical and application information here on our complete line of Sway-A-Way Suspension Components and accessories.

ON LINE CALCULATORS are available to calculate spring rates, wheel rates, dual spring rates, torsion bar rates and more for a variety of different suspension designs. The nature of suspension products lends them to many varied applications of one part number. Proper selection, use, installation, and maintenance may require prior suspension knowledge and familiarity with your particular performance requirements. Feel free to utilize the tools in this Tech Room and/or our experienced staff to assure the best selection and use of Sway-A-Way products.

Instructions: Before taking apart the suspension, level the car and measure and record the spring plate angle for later reference. The spring plate angle is measured with no pre load on the torsion bar. Find the new bar diameter and pre load angle in the chart. Use the pre load angle from the table for setting the new bars to get stock ride height.

NOTES: These values are approximate. The angle reference is the top edge of the spring plate from horizontal down with no pre load on the torsion bar. All angles are calculated to maintain stock ride height. The ride height changes by 1” for each 3 ½ degreed of pre load, EXAMPLE: If you want to lower the car by 1”, reduce the table pre load by 3.5 degrees.

NOTES: These values are approximate. The angle reference is the top edge of the spring plate from horizontal down with no pre load on the torsion bar. All angles are calculated to maintain stock ride height. The ride height changes by 1” for each 3 1/2 degrees of pre load.
EXAMPLE: If you want to lower the car by 1”, reduce the table pre load by 3.5 degrees.
