For over 30 years Titan Mainsprings have been supplied worldwide to airgun enthusiasts, professional airgun customisers and the Gun Trade and have established themselves as the top quality mainspring against which all other mainsprings are compared. Only the finest quality Grade 1 Swedish Silicon Chrome Vanadium Spring Steel is used. We use no mass production methods. Every spring is hand wound to an exact specification, then heat treated and tempered to ensure ultimate performance and maximum durability. During final tempering, they are coated with a specially formulated hard, but flexible finish. This is a high technology coating and its self-lubricating multislip properties eliminates the need for conventional spring lubrication.
The almost friction-free operation of the Titan XS Mainspring reduces the possibilities of dieseling to a minimum and increases power by up to 40% for FAC rated air weapons. Maximum power is maintained for longer than most other springs. Titan XS Mainsprings do not lose power when left cocked for long periods.
All Titan products are fully guaranteed.
