PA28-180 Power Contactor Relay source?

I've been trying to find this part on-line without much luck. It is listed
in the Piper parts manual as 455151 but also referred to as 6041H105A. It's
the relay mounted along side the battery box. My Archer has been cranking
rather slowly even after replacing a dying G-35 with a new RG-35AXC battery.
This relay was almost too hot to touch 5 minutes after starting and then
shutting down the engine.

Definately get the part called for in the parts manual (or its equivalent).
Those type of solenoid relays come in (at least) two varieties: intermittent duty
(e.g. for engaging starters), and continuous duty (what you need). If it gets that
hot, it's possible someone replaced it with an "AutoZone Special" intermittent duty
solenoid.

Check with the recyclers - Wentworth, White Industries, Central
Airmotive.

Cessna, Maule, piper all use the same relay. Mine is a cessna part that
has the same part number as my original.
Check out Cessnaparts.com

work there is always tech support.

The number you gave, 6041H105A is a Cutler-Hammer number.

The planes all use variants of this. The differences are things
like the diameter of the stud bolts.

BTW, as these age the phenolic tends to shrink. The stack
of nuts gets loose.

I've had some luck just loosening the nuts and re-torquing them
from the bottom of the stack up. On the stud bolts that is.

You can get it from a piper dealer, but it isn't cheap. Last I looked,
it was running about $340, and that was 2 years ago.
