Standard style 50mm strut rubber gaiters (fits KYB, GAB etc)

If old rubber gaiters are torn or missing you can use ones listed below.
Price is around £7 to £10 each pending on where you source them, I get them from motor factors & had Monroe PK036 for some gabs that needed clean up & new springs.
Uk factors tend stock a lot of KYB so that kit is KYB913138

you can get them on eBay but local factors should have some that will fit & expect cheaper too .

good link but if you use universal steering rack gators there even cheaper and can pick them up from a local motorfactors

Not much of a link to be honest ... actually no link lol
I found UK factors stock most of KYB gaiters so they easily sourced if needed. Mentioned eBay as a lot of you guys like buying that way if not a regular with a motor factors.
Bumps may need slight hole reaming for slightly bigger diameter rod in rears & on some GAB KYB performance struts.
Loads of companies make boots that fit such as: MONROE PK036 036, KYB 913138, MAPCO 34502, NK 692201, OPTIMAL AK-735113 A735113, QUINTON HAZELL 300211, SACHS 900 027 900027, TRW JSK122 122 .
