ﾕ 30mm internal bore ﾕ Mono tube design ﾕ 12.5mm double chromed shaft ﾕ 50/50 damping ﾕ Coil-over design. How to make a steering damper more effective without hampering the smooth lock to lock movement? What about increasing the damping ratio and adding a coil-over spring? This amazing steering damper is a revelation, quite simply the Terrafirma RTC steering damper out performs all conventional steering dampers hands down! The fact is when very large tyres are fitted or when you run consistently low tyre pressures even the best steering dampers fail to cope, feedback through the steering wheel increases and returning the steering wheel to centre becomes hard work. Not to mention the effort required to make quick direction changes. Fit a Terrafirma RTC steering damper and feel the difference instantly, the coil-over spring compresses and stretches from lock to lock dramatically reducing the return to centre effort, the spring also works in harmony with the damper eliminating shimmy and vibration. Finished in silver metallic with stylish Terrafirma RTC logo and bright blue coil-over spring this steering damper looks as good as it works. For vehicles fitted with more standard size tyres drivers will experience the benefit of quick and effortless steering.
