Member Jonathan Kay Posted July 23, 2018 Member Share Posted July 23, 2018 The most commonly used alternatives are from Powerflex. You might be able to work backwards from their part numbers to find the sizes.NB differences in the A-frame as noted in post #2 of that thread.Jonathan Link to comment Share on other sites More sharing options...
Area Representative Geoff Brown Posted July 23, 2018 Area Representative Share Posted July 23, 2018 Powerflex have complete sets specifically for Sevens. All you need is the year & if the suspension is Imperial or Metric.The only odd sizing is the front & rear anti roll bars as diameters differ. You need to know the diameters to complete the set.
