The new “Big Bore” socks are equipped with separate piggyback with opposed piston.
They are not adjustable and work with normal silicon oil!The bigger diameter and the separate piggyback with opposed piston facilitate very constant function of the shocks. Therefore traction and driving behavior is positively influenced in corners.
The shocks are delivered with the special ball end and steel bushings from H.A.R.M. Racing.The shocks are not filled with oil and the oil is not included.
We recommend for the first filling in the front #1515860 shock oil 60 and in the rear #1515856 shock oil 40.
For these shocks special barrel springs are available in different hardness with bigger diameter upper. Inner diameter upper 20,5 mm, inner diameter lower 16,5, length 52,5 mm.
For the H.A.R.M. SX-3 Chassis we recommend: #1512578 barrel spring yellow in the front and #1512576 barrel spring blue in the rear. The shocks are available also a set with 4 pieces # 1512510.
