NP205 LoMax 3-to-1 Gear/Case Kit
Info and Reviews
JB Conversions has developed a brand-new NP205 design
nodular-iron case, as well as the larger LoMax 3:1 gears that go inside
it. JB Conversions began their success by offering high-strength gearsets
for the Dana 300 several years which was also marketed under the LoMax
brand name. The NP205 LoMax Gear/Case kit comes with a new case,
cover, and five full gearsets.
The new gear sets are manufactured to high tolerances
using 8620 alloy standard to the gear industry. Heat treat processes and
hardening are being performed to exact New Process Gear specifications as
dictated by the original OEM NP205 drawings.
The new LoMax gear case is a high quality ductile iron
casting. The new case is fully compatible with the stock NP205 shift
forks, output shafts, shift rails, bearing retainers, etc. The GM round
pattern (6 bolts) and the long 8-bolt pattern are present in the front
face of the case. Although not shown in the front view photo above,
alternate bolt holes will be provided to allow an upward rotation of the
new case. Our goal is to provide the owner of a stock GM NP205 with a new
case that will directly replace the original with no changes to driveshaft
length, shifter linkage, etc.
When totally assembled, the LoMax 205 weighs in at 135
lbs. The bottom inspection cover is equipped with an optional mounting
boss to accompany the side mount common to the stock GM case.
