JIMS, Powerglide upgrade pushrod kit

Used on 66-84 Shovelhead models that are equipped with JIMS Powerglide tappets (MCS 978103, 978104 or 978105). This pushrod kit includes Pro-Lite Worksavers, made from aerospace quality heat treated aluminum, without oil hole since that is not necessary on Shovels. Comes with four new 3/8" diameter pushrod seats that will 'shorten' your existing Powerglide tappet. This is done to reduce the severe pushrod angle, that is found on Shovels, closer to the Evo design. Complete with instructions.
