The Century Spring Corp 16 x 165.1 x 1.4mm extension spring is a 2 pack of steel springs that absorb and store energy while resisting pulling forces. Each spring is made from high-grade spring wire and manufactured to commercial tolerances defined by the Spring Manufacturers Institute (SMI).
As a longer, fine-wire tension spring it stretches under load and pulls back to its free length when released, suiting repairs and assemblies that need a controlled return action over a greater range of travel.

Great value for money
Spent a while looking for the right Century Spring and this kept coming up as the best value. I can see why — quality is impressive for the price. Delivery took just 2 days to Townsville which is great. Packaging was solid and everything intact. My partner and I both use it daily now. Highly recommended.

Fast delivery and perfect condition
Fast delivery and exactly what I ordered. Very happy with this.
Outstanding value
Bought this on a bit of an impulse after seeing it on the site and really glad I did. Quality is much better than the price suggests — feels premium and well made. Ordered Monday and it arrived Wednesday in Sydney. Nothing loose or damaged. A few people have asked where I got it.
Good buy — fast shipping
Really good value — compared it to similar products at twice the price and there is very little difference in quality. Fast shipping and arrived in perfect condition.
