Springs had nics in the end loops. Looks like a pair of pliers gripped the spring to form the loop. This little nic will be a point of failure. I bought two different springs and they both had these little nics in each end.

Be aware these springs are NOT exact replacements for the Rotax springs. These are approximately 5 mm longer. When the Rotax springs are stretched 1/2”, these longer springs have about 80% of the tension as the Rotax springs. And about 50% of the tension as compared to the Rotax spring when stretched 1/4” due to their greater length. Just be aware of the difference. I returned mine.
