Infinity IF18-3 Optional Shock Shaft

As their first optional release of 2026, Infinity are introducing a new shock shaft design developed to further enhance the performance of their IF18-3 1:8 Onroad car.  This technical update eliminates the traditional E-clips normally used to retain the piston on the shaft and replaces them with a screw-type fixing system.  The concept has already been successfully adopted for their IF14-2 1:10 Nitro Touring Car, and now they have now extended it to their flagship 1:8 platform.  By adopting a new structure that provides 3 mm of top clearance, the system increases stroke capacity while optimising oil flow.  At the front, initial response is improved, and at the rear, traction and “kick-out” feel under throttle are enhanced, boosting overall grip performance.  Furthermore, by switching the shock piston fastening method to a threaded design, the shock shaft length is shortened and optimised by 3 mm for both the front and rear, delivering a more stable driving feel.
