Avid Ringer Shock Collar Sets
Avid Racing Concepts has released 12mm or 13mm Shock Collar Kits to allow you to run either 12mm or 13mm springs on AE 13mm, TLR G3/3.5, and Schumacher LD3/L1R shock bodies. The kit includes 4 threaded shock collars that feature offset laser-etched Avid logos for ease of matching spring tension left and right in 1/4 turn increments with a silver ringer highlight machining. These collars will ensure proper spring fitment without the use of 3d printed adapters and feature standard internal oring design for holding the collar in position.
