So the m205 is not NEEDED to do a titan swap. I can get it later when I have the cash for that kinda thing?
Correct. However, if you go the R180/extended half axle route, you will need to source new half axles, or assemble your own.
PRG offers the extended half axles (no CV's) for about $400...then you need to add your stock inner and outer CV's on your own.
Or, go the Nisstec route, providing your stock half axle cores and they build you a set, about $700.
A brand new M205 is about $1,100, and Cardone half axles usually run around $60 each.
IMHO...don't buy a used Titan Swap, which is the route I took. Sourcing new parts for this critical install would be my recommended route. The 2.5 Radflo's that I got used ended up being blown, resulting in an additional $210 rebuild from Radflo, plus the 4 day down time off the truck. Also, the homebuilt half axles were never quite right, so having those built/sourced professionally the first time will save you a bucket of time and frustration.
Out back, you will need a good set of leaf springs and extended shocks. I used Alcans from Nisstec, and a set of extended Bilsteins from Off Road Warehouse locally. Or, you could just source both from Nisstec and kill that shipping bird with one stone.
I also used PRG extended shackles with the Alcan leafs, which were a 4" arch/lift and a 450lb. spring rate. Again, hindsight is 20/20, but the one thing I would add to the mix of rear end suspension is the oft spoken/installed Timbren bump stop upgrade. These easily install on top of your upgraded leaf springs, and will make your ride off road much smoother with the stiffer, but more flexy leaf springs.
So, a quick check list:
M205 route:
M205 - $1,100 new, $600-$700 used
Cardone half axles - $120
R180 route:
PRG extended half axles, DIY - $400
Nisstec extended half axles, DIFM - $700
Titan Swap General:
2.5" Coilovers - $800 used, $1,200 new
Titan Upper Control Arms - $700 new
Titan Lower Control Arms - $250 new
Extended brake lines, front/rear - $180 new (don't buy used brake lines
)
Brake fluid for bleed - $7.50
Alcan or similar rear leaf springs - $750/$800
3-4* leaf/axle shims - $40 (this sets the drive line/pinion angle for the lift)
Rear spring U-bolts - $40
Rear wheel spacers to match front width - $100
Misc. hardware - $100
Am I missing anything?
