Brad asked for an apples to apples comparison, so I gave him one based on the assembly price quoted in YOUR POST - same parts, same manufacturer.
For the reason I mentioned in my previous post, a 35 spline 9" Detroit Locker is not in the same league as a 35 spline Dana 60 Detroit Locker or S-Trac.
The only 9" traction differential that compares (strength wise) is an S-Trac ($) or Wave-Trac ($$)
For the sake of argument:
Strange sheetmetal housing with ends welded on - $525.00 Strange Pro HD center section with a spool, 4.10 gear, and billet yoke - $1245.00 Upgrade to Detroit Locker $300 Strange axles with bearings and 5/8 studs - $515.00 TOTAL $2585
Note, the cost of a 9" built with a sloppy Detroit Locker is still greater than an S-60 built with a tight/smooth S-Trac differential.
