Darkhorse Crankworks

A-model Shortblock Remanufacturing

WELL known for their crankshaft remanufacturing, the Newton, Wisconsin based Darkhorse Crankworks division of Hoban Brothers has now introduced an A-model Shortblock Remanufacturing program.

Following Harley's decision to close its own remanufacturing program last year, Darkhorse has designed a program for their dealers that "provides an economical method" of remanufacturing 2007 and later Harley engines.

Darkhorse's General Manager John Dahmer told AMD that "we know most of our dealers currently provide cylinder boring or valve/headwork for their customers, and we don't want to compete with them, so designed this program to help make their dealership more profitable.

"A dealer can send us a complete lower end and we will manufacture it back to better than new specs at very attractive prices."
Darkhorse utilize their proprietary Pro-Plug system to "ensure that the crankshaft stays truer, longer than any OEM replacement crankshaft, and we back that up with a two-year unlimited mileage warranty.
"Our skilled craftsmen verify all tolerances to meet or exceed all OEM specs on the entire crankshaft and crankcases, which provides the strongest foundation for all stock-type engine configurations."

For builds larger than the OEM 96" or more powerful performance engine configurations, Darkhorse offers upgrades including proprietary connecting rods, crankshaft balancing, DHC engineered Timken bearing upgrades and any other crankcase modifications on request.
Dahmer went on to say that they sonic-clean the crankcases and replace all bearings with OEM or other upgrade options. "It is the attention to detail that results in value and durability. For example, main bearing races and connecting rods will be replaced if out of tolerance, and the crankshaft will be assembled and trued within .0015" at the main bearing races, using only genuine Harley-Davidson main bearings and OEM connecting rods."
