Many manufacturers are now making these rear coil springs on a modern day standard former meaning they have the incorrect internal diameter (too large).  When fitting these springs, they can not be concentrically located or evenly compressed which will interfer with the spring rate, consistency and possibly even create a rattle on your rear end.
 
We are now producing these with the correct 2 1/2" internal diameter as Jaguar manufactured in period, whilst uprating from the standard spring rate to our Sayer specification fast road rate.

 These new uprated springs are manufactured in the UK and heat treated to ensure optimum hardness and ultimate performance. The surface of the springs is shot peened and then powder coated Black to ensure a long rust free life.
