LoMax for the Dana 300 - Info and Reviews
The LoMax gear set has been designed to achieve maximum gear strength
and the lowest possible reduction ratio for the Jeep Dana 300 transfer
case. For over 2 years, the LoMax gear design effort has been an
independent project of JB Conversions, Inc. and bears no affiliation with
any other aftermarket gear manufacturer. The LoMax design features that
set it apart from others are incorporated into all areas of the gears.
Tooth volute shapes and face finish, gear hub thicknesses, and
manufacturing tooling & processes yield a gear set far superior to any
other gears being produced for the Dana 300. The LoMax gears were designed
as a complete 5-gear "set" from the very beginning. This means there were
no strength-limiting tooth size restrictions forcing the new gears to mesh
with smaller stock gears. As you will see in the accompanying photo
comparisons, the result of this "clean slate" philosophy is a set of gears
with massive, helical gear teeth with tremendous strength capacity.
Another practice commonly used in aftermarket gear production is one that
we have chosen NOT to adopt. This practice involves the use of two piece
gear construction. Several of the gears used in competing gear sets are
manufactured using a process which calls for pressing and welding two
gears together to form one piece. This two-piece process allows for a more
simple manufacturing process and much cheaper gear cutting tools. The
strength of a solid gear over a comparable sized two-piece gear is
indisputable. All LoMax gears are cut from a single slug of alloy. The
cutting tools required for this type of construction are extremely
expensive however we feel the benefits are well worth the investment.
The LoMax gears are not entirely new. They have been proven without fail
through the rigors of western rockcrawling and the high throttle abuse
characteristic of the Tellico area of North Carolina. The LoMax gears are
compatible with both the long and short tail versions of the Dana 300.
Although not required, it is highly recommended that a complete rebuild
accompany the installation of the LoMax gears. Supplimental rebuild kits
are available from JB Conversions, Inc.. New detent springs are also
supplied with our gear kit. We have found in many cases that twin stick
applications will create a tendency for disengagement of the clutch rings
while under load. Often this condition is amplified with the installation
of lower range gears. For this reason we recommend the use of the two
detent springs supplied in the kit.
