I am looking to install drive showers. Can anyone make some recommendations on which ones to get and where I should purchase them? Thanks.

I am running a Simrek shower on my XR/Imco Shortie drive. It is my second Simrek and would not consider anything else. No more heavy deposits of calcium and magnesium on the drive.
You can buy them direct from Simrek.

C.P.Performance, Teague, I.M.C.O, just a few makes. I've seen the best temp difference using a drive temp guage with the imco s.s cap style.

In a word...Simrek. Independent tests show they are the coolest . They are also simple and cheap.
Just have to watch external streering clearance problems.

go with the simrik.i have temp gauges on my drives and they make a huge differance.

Thanks. I'll check them out. Lost my starboard drive end of summer. Don't think it was heat related but while it was getting fixed I had a lot of people say I should put the showers on. Good insurance.

Get the Simrek "halo" drive shower. Those are what I use on my XR drives.

I have used most every shower over the years and I found the Simrek to produce as offered.....
