These are the Avid RC TLR 22 5.0 Ringer Shock Standoffs. Intended as an optional accessory for the TLR 22 5.0 these are a direct swap for the kit included standoffs. Constructed from 7075 machined aluminum each standoff is fully threaded to help prevent bent shock mount screws. Included are Delrin pivot bushings allowing the shocks to rotate freely along with providing a long lasting, low wear surface. Overall these are an excellent addition providing durability and consistent performance.
