Traxxas 4×4 Tuning Springs
Looks like Traxxas has come out with another set of ‘most have’ hop-ups for the Traxxas Slash 4×4! These new progressive-rate Tuning Springs sound pretty cool. The progressive-rate design allows you to take small bumps without compromising the need for strong springs on the big air! They are color coded, 20% softer than stock are orange, 10% softer are green, 20% stiffer are blue, and 10% stiffer are pink. Front springs will run you about $5 and rear are $6.50.
