any one know anything about putting a compression brake on a 4BT?
I asked a guy at an injection shop about it one time.
he said people do it on dodge rams with 5.9,
that you have to put in stouter valve springs, and that there was a kit.
but he didnt know about the 4bt.

I drive my 7 ton bread truck on logging roads in the cascades and coast range in Oregon all the time.
a little help slowing down would be awsome.

Yes it can be done. Search for engine brake, jake brake in the stickys. Also need to upgrade to 60lb valve springs. Vendors on the site have the parts and knowledge you need.
