The Yokomo RP-083PI is produced as an RP Ultra front off-road spring tailored for carpet and astro turf circuits. It focuses on stability where mechanical grip is high, delivering repeatable rebound characteristics and more controlled landings compared with softer or older spring variants.
In practice this spring alters how the front end behaves over jumps and during gap transitions, offering improved landing predictability and smoother chassis movement through technical sections. Racers typically adjust preload and match rear spring rates to dial in the intended balance for indoor layouts.
Fitment advice: this is a dedicated front suspension spring for the chassis listed below. Verify your spring seat and retainer dimensions before installing to avoid fit issues.
