"Weight Reduction List" Fully Updated!
I just swapped out my generic 165 R15 radial fronts for some 26"x4.5" MT ET Fronts and put them on a refrigerant scale for those interested. The generic radials are 17lbs 6ozs and the MTs are 11lbs 6ozs for a total of 12lbs off the nose.
M&H Racemaster Front Tires P185/75R15
They weighed in at 19 lbs each. They are 4 ply and the load is 1323 lbs

Took some weights today with our utility scale:
Bare Moser M9 Housing 74lbs
Moser Aluminum Thru-Bolt Centersection with 40S Spool and 3.25R/P 59lbs
Left side 40S Axle with backing plate and E Brake housing 24lbs
Right side 40S Axle with backing plate and E Brake housing 26.5lbs
Torque Arm with all 3 Heim joints and bolts 19lbs
Both LCA's with Heim joints 6lbs
Panhard Bar with Heim joints 5lbs
So a complete M9 with 40spline axles and aluminum CC and Spool = 183.5lbs including the E Brake set-up. E Brake is roughly 10lbs total for both housings.

more info
The spindle weighs 10.8lbs each, a pair weighs 21.6 lbs
Strange brake kit for both sides weighs 33.5 lbs both the first gen and 3rd gen brake kits weighs the same 33.5 lbs
4th gen kit weighs 37.56 lbs.
The same stock parts weigh 97.2 lbs a weight savings of 42.1 lbs.
Stock K-member 47.4 lbs
Racecraft Inc. 15.6, LT1 18.3, LS1 20.2 lbs.
Stock lower arms 15.6 lbs.
Racecraft Inc. 8.4 lbs.
Stock upper arm 5.3 lbs.
Racecraft Inc. upper arm 4.2
The Racecraft spindle mount spindle will accept the Strange single piston brake kit which weighs 15.5 lbs. So that set up will weigh 28.7 lbs in a few weeks, 68.5 lbs. less than stock.
Thanks, Mark

Hey this doesn't have anything to do with weight, but since we are on the topic of front wheels and tires, I need a bigger tire for my front runners to raise the front end up more.
I have 185/65/15's up front right now.
