Shovelhead riders may be interested in upgrading to Jims Powerglide tappet blocks. These blocks are machined to accept Evolution tappets, so you get the benefits of Evo technology, including higher revs and lower maintenance in your shovelhead motor. The kit comes with hydraulic tappets and lifters ready to install.
There are a a number of quality replacement lifters available for Harley Davidsons. Andrews and Jims are excellent. Fueling and Harley Davidson lifters are also very good. Our first choice, however, are S&S lifters.
