It fit and accomplished what I need to accomplish.I put a newer style stainless flex fan on a vintage car, the car wasn’t overheating however I wanted a fan that would move more air for around town driving. When I installed the fan it was too far back so the spacer enabled me to install it with correct fit.

Read older reviews that said the mounting bolts were too short. Thought this would have been corrected. Manufacture must not read reviews

Works as it should and should last? I went from OEM fan clutch measurement and ordered this Derale spacer for the 19″ derale flex fan. I could have used the 2″ to move fan blades further closer to radiator and inside the shroud.

Like many others said, the bolts were too short. I’m using a regular fan without a clutch.

Came with two sets of bolts so they should work whether you need fine or coarse thread. Fan is much more efficient and placed where it should be now.

Simple easy product but bolts included are way too short for use with any average fan hub. Not the end of the world but rather inconvenient to have to locate bolts to compensate for poor product testing.
