mcman56 Posted July 21, 2019 Report Share Posted July 21, 2019 I bought a 2016 300 4t last year and noticed that American Beta sold an oil pump upgrade kit to decrease engine braking. I believe it was the same as the 2018 models so I bought one. I got used to the engine braking before installing so this past year it just sat in a cabinet. Recently, I have been going back and forth the between the 4T and a 2T and the engine braking was the most challenging part of transition so I finally installed the upgrade. It is just a slightly wider (3/16" maybe) pump module. It makes a significant difference. I actually forgot about the install for about 1/2 of the first ride back on the 4T and did not notice braking so it did the trick. Link to comment Share on other sites More sharing options...
carlos Posted July 24, 2019 Report Share Posted July 24, 2019 Very interesting, never new they had this. Part numbers? Price? how easy was the install? Link to comment Share on other sites More sharing options...
mcman56 Posted July 24, 2019 Author Report Share Posted July 24, 2019 You need to pull the flywheel so need the appropriate puller. Then it is just a couple of screws to remove the plate...pretty easy. Instructions are in the link. https://shop.betausa.com/p/evo-4t-oil-pump-upgrade-kit-09?pp=12 Link to comment Share on other sites More sharing options...
