SU DAMPER SPRING – BLUE (2.5oz) – [AUC4587BLUE]

Weak damping carby spring rarely used on single or twin HS2 (1-1/4) & HS4 (1-1/2) on Minis.

Standard was AUC4387RED which is a stronger spring. Notable exceptions to this where for the 997/998 Cooper from 1964 to 69 & special H4 tuned Carbs which used AUC4587BLUE. Both the 2 & 4 Door Wolseley & the Riley 1300 & 1300GT early Sprites and midgets until 1972 where they then changed over to the: AUC4387RED

Now depending on your engine size & the carby/s size that is in your particular car you may to change spring/s.

• Red/Stronger spring is: AUC4387RED
• BLUE/Weaker spring is: AUC4587BLUE
