Harley 447-30 446-37 U UL ULH Engine Motor Case Kit 1937-1942 Cad USA
$66.95
You are purchasing one new motor case fastener kit for all 1937-1942 or early 1943 big twin flathead U models. This will fit up to 1948 but is "detail-correct" for '37 to '42 due to the plain head machined bolts. 1943-1948 used CP-1035 bolts. This is everything you need to join your motor cases. We have this kit in a Parkerized finish, we also have the 1943 to 1948 kit as well as Knucklehead, Panhead and 45" kits and we stock this with cad nuts and bolt on another listing.
The hardware is spot-on and American-made. The studs and bolts are correctly heat treated to prevent stretching and are machined exactly like the originals. The bolt has the 1/2" hex on it as original. The nuts are machined exactly the way Harley did it back in the day and the Parkerizing & cad plating is beautiful. You get what is pictured.
We stock many hard to find NOS, good used OEM, and reproduction parts for 1915 and up Harley-Davidson models. We also manufacture and sell the most highly detailed wiring kits for every USA made Harley-Davidson motorcycle from 1926-1969.
