Couldn't load pickup availability
This bracket kit sets up your pump and reservoir the right way on an LS3 DBW engine using a head-mounted CBR pump configuration. Everything is designed to mount clean off the cylinder head using the Camaro accessory drive layout, keeping the system tight, compact, and where it belongs.
You’re getting both the pump and reservoir mounting brackets along with the correct spacers and Grade 8 hardware to hold it all together. The spacing is already figured out, so the pump lines up properly and the reservoir sits where it should without fighting for clearance.
