The strength and rigidity of this quick install pushrod is second only to heavy duty one piece pushrods. Our tube material starts out as 7\/16” rod OD, it then gets turned down to 3\/8” OD leaving heavy duty 7\/16” – 20 threads for the base and jam nut. The jam nut slides up the pushrod, the base then loosens up into the pushrod to shorten length and allow quick install access.\u003cbr\u003e\u003cbr\u003eIncludes pushrods and 6061 Billet pushrod tube kit. Provides even more working room when adjusting the pushrods than other tube kits on the market. Tube kit contains retaining clip, inner tube, spring cup, lower tube and washers\/spacers (M8 use thin spacer, TC use thick spacer). See Feuling gaskets kits or Cam install kits for pushrod o-rings.
