TIME-SERT Add On Kits 5588 and 5678
July 15, 2015 TIME-SERT Kits No CommentsDennisB DenLorsTools.com © Summary: Dennis discusses Time Sert add on kits for doing triple oversize spark plug thread repairs when a hole is too big for a regular Time Sert (Big Sert) kit. *Note, a Big Sert kit must be used in conjunction with the 5588 for the largest repair which is the triple oversized one. And the 5678 must be used along with components from the 5600 kit. Our kits are made in the USA and are professional grade. Repair shops and many do-it yourselfers love our kits. It’s the engineering and design that makes the difference. Use one and you’ll know first hand. And the best part is that Time Sert spark plug thread repair kits are used without removing the cylinder head, by working right over the fender!
