5 - Product Review of my new 1 Ton 1350 CV Driveshaft from
High Angle Driveline
First question. Why did
I choose to get my driveshaft from High Angle Driveline, all the
way in California? Simple Answer - they are the best.
Why are they the best?
1) The product is the
best. Jess understand and caters to the hardcore off-road crowd.
His shaft can be found in more top rock crawling competitors rigs
than any other. He does what other driveshaft shops will not or
can not do. His is the only shop offering a true, re lubable, 32*
capable double-cardan CV style driveshaft. Period.
Also, High Angle Driveline
driveshafts are built with improved balance and stiffness that result
in less drivetrain vibration and component wear, as well as improved
driver comfort, and reduced noise. The Hytrel™ thermoplastic
booting provides High Angle Driveline driveshafts with enhanced
protection against environmental contaminants, increasing component
life. It has been proven to reduce maintenance and downtime, having
undergone extensive environmental testing in temperatures ranging
from -40°F (-40°C) to 220°F (105°C).
High Angle Driveline
Heavy-Duty Driveshafts offer:
• Larger diameter slip member with longer involute splines.
Long travel shafts available with up to 18" of slip-spline
• Long life - built from the best Spicer components, custom
machined, fully welded, and available in .083, .120, and even .250
• Re lubable slip spline
• Reduced maintenance - Net-formed Spicer Life series U-joints
• Custom precision machining and balancing
• Increased torque capacity
• Personal hand crafting and the best customer service in
2) The customer service
is the best. Jess is one
of those few, very rare vendors that truly, truly stands behind
his product. he calls YOU to make sure you are happy and satisfied.
He goes that extra mile, no questions asked. He also freely contributes
knowledge and experience to the BB here at Pirate4x4, even when
doing so may help someone in a manner that might cost him a sale
(like helping with junkyard part numbers or dimension - instead
of just trying to sell a joint or yoke) - now That's unselfish dedication
to the hobby/sport and it's fans - you and I. Not only that - but
he extremely generously gives away driveshafts in monthly drawings
to Pirate4x4 BB members!! My own incredible story of customer service
experience with Jess is told
how my driveshaft arrived. A far cry from the last driveshaft I
ordered from a US "specialty shop" - that one arrived
half unpainted, scratched, and with only a bit of tape holding the
u-joint caps on - no packaging at all.
||In contrast - my High
Angle shaft was solidly and carefully packaged. Good thing too - considering
the trip it had. You see - Jess
shipped my shaft to me UPS, all the way to Nova Scotia, Canada. For
reasons unknown to this day - Canadian or US customs or UPS brokerage,
I don't know which, refused to let the package cross the border/clear
customs (despite the outrageous brokerage fees UPS charges), and bounced
it back all the way from Montreal to california. Jess
immediately phoned me, apologizing profusely (even though it was in
no way his fault). He explained that, when he phoned to straighten
it out, UPS told him the package wouldn't clear without my Social
Insurance number on it. Jess
defended my privacy rights and watched out for my security without
me knowing or having to ask, by telling them to pound sand, and that
that wasn't good enough. Eventually, after wasting a lot of his valuable
time, he was able to get them to relent and agree that my phone number
was enough. he wasted no time telling them what he thought of that
- seeing as that was what he had originally had on the package!! Anyway
- in the end, he ate the nearly $90US double shipping charge, and
re-sent my package immediately. It promptly arrived, unscathed!
You may have already
read how I am a HUGE fan of well packaged products - perhaps just
because I've been so disappointed in the past with shoddily packaged
goods. But I think it's more than that. It really shows pride and
care in a product, and it says "I care about how my product
gets to you - not just about your credit card number"
I like that - a lot!
So I love this package - just look at the super sturdy packaging!
||Inside the 1350 CV shaft
and patented 32 spline flange (U.S. Patent USD 462,256,S) are carefully
||The package includes a
new mounting nut for the transfer case output flange, and 4 high-strength
12 point socket head cap screws for securing the Driveshafts CV socket
yoke to the custom transfer case output flange.
||The custom machined, 32
spline transfer case output flange. This flange is available for New
Process (NP) 203 or 205, 32 spline HD fixed yoke conversion kits (e.g.
Advance Adapters) for the NV 231, Advance Adapters, JB conversions,
Tera Mfg., etc) Atlas with 32 spline output, and Dana 20 and dana
300 with Advance Adapters 32 spline output conversions.
||The flange is also available
for 26 spline output shafts, such as in the Dana 20, Dana 300, NP
207, 231 & 242, and 26 spline Atlas. However - 26 spline outputs
are not recommended as being a good match with a 1350 1 ton shaft,
as the shaft is now much stronger than the transfer case output.
||Close up of the beautiful
machine work. Check out the splines. Be aware that switching to the
High Angle Driveline flange will shorten the length your driveshaft
needs to be by 1/4"
||The transfer case output
flange and CV socket yoke flange (see how useful that new vocabulary
is 0 you know exactly what I mean, don't you!) come marked with a
flash of bright paint so that they can be installed with proper original
phasing, as manufactured and balanced at High Angle.
Here's a peek at the
heart of the system. the ball and socket assembly of the CV centering
yoke are DEFINATELY NOT stock. They are specially modified and machined
to be stronger than stock Spicer components, capable of much higher
angles, and still lubable (see grease fitting in pic).
High Angle is the ONLY
driveshaft shop building 1 ton 1350 CV shafts like this!
||Here's a shot of the whole
package together - shaft, flange, and mounting hardware. The 1350
CV driveshaft as pictured is normally available in lengths from 135/8"
||A close-up of the CV head
assembly, showing off the CV joints high angle capability. Capable
of running at 32°.
||The shaft is fitted with
3 of Spicer's latest and greatest Spicer Life Series universal joint,
in 1350 series.
||An interesting feature.
Jess welds up the welch hole. The reason is, if it were left open,
should the driveshaft ever be submerged in water / mud, and extend
while so submerged, it would act like a big ol' turkey baster and
just siphon up a big gulp od mud / water This would almost certainly
then sit inside the shaft and the cause unnecessary wear and corrosion
to the slip member splines. For extreme off-road use, it is better
to leave it closed.
||When he builds you a 1350
1-Ton CV driveshaft - Jess starts with the best Spicer OEM components...but
that is only the beginning. I can't tell you exactly what magic he
works, as that is a trade secret. But I can assure you, the CV joint
is significantly worked over, resulting in greater strength and much
greater operating angle capability than any stock Spicer unit.
||Just look at the attention
to detail and fine craftsmanship. It's a beauty, no doubt. Standard
travel in the slip member is 5" for a rear shaft like this, set
at 2" compression and 3" extension. Of course, many other
configurations are available. For example, standard long travel shafts
offer 12-14" travel in the slip member, usually set up for 3-4"
compression and 8-9" extension.
||Here's a shot of the pinion
end. The shaft comes with all the U-joints installed and lubed, ready
for use. You just need to install it and go.
||Here's another shot of
the complete package - 1 Ton 1350 CV Driveshaft, custom machined,
patented (U.S. Patent USD 462,256,S) 32 spline output flange, and
all the necessary installation hardware. The standard tube size is
3" .083" wall tubing, which is light, stiff, balances well,
and has a strength at least equivalent to the 1350 CV joint. For those
who require or desire it, High Angle Driveline can make your shaft
with either .120" wall tubing or even .250" The latter is
only for very special requirements, as it is hard to balance, and
spinning a shaft of that much weight is hard on the other drivetrain
||Here's a pic of the junk
I was replacing. Due to my suspension, drivetrain length (with dual
transfer cases) and wheelbase, the slope between my transfer case
and rear axle pinion is pretty high. The yellow arrow shows the butch
homebrew redneck booty fab method I had employed to prevent the shaft
from binding. Clearly, I was well beyond the design limitations of
||You can clearly see where
I had ground the yoke for clearance. This does nothing for strength,
reliability, or to combat vibration and noise!
||Here's one last pic of
the rusty, poorly welded, unbalanced, out of phase, banana shaped
shaft that had to go!
||Old vs New. What a difference
||Just look at the beefier
yokes, and much bigger and better u-joints. Notice the increased dimensions
of the new Spicer Life bearing caps
||More beef, better machining,
perfectly balanced, bugger joints....what's not to love!
||Installation is straightforward.
refer to Section 2 of this article for further guidance if required.
First I removed the transfer case output yoke and retaining nut. Then
I coated the splines of the new flange with RTV to ward off any leaks,
and installed the flange onto the transfer case output shaft.
||Coat the face of the nut
with RTV, and apply a little Loctite thread retention compound to
the internal threads of the nut.
||Install the nut and torque
to at least 150 ft .lbs.
||Then simply mate the driveshaft's
CV joint yoke flange to the output flange, and secure with the 4 supplied
12 point bolts. The bolts come with retaining compound already impregnated
in them, but Jess recommends using Loctite anyway, and tightening
them to 80-90 ft. lbs.
||The axle end just installs
as normal. Remember to be careful not to over-torque the bearing cap
retention hardware, as this distorts the cap and increases premature
||When you're tightening
the fasteners, take your time, do them in a gradual, cross pattern,
and you will have no difficulties.
||Her it is, all installed
and ready to go. At rest, my shaft operates at an angle of about 27*,
which is pretty high. See if the High Angle Driveline 1350 CV shaft
is up to the task, below in the testing section.

Of course, shortly after
installing the shaft, I had to take it out and absolutely romp on
it. The funny thing was, the thing that amazed me most, was not
what I was expecting. I was expecting, because of his skill and
reputation, that the shaft would easily handle my abuse, and I wouldn't
What I wasn't expecting,
was how amazingly much more pleasant and enjoyable it was to drive
my buggy with a quality, balanced, driveshaft operating within it's
angular capabilities. You see, my buggy is, obviously, a rugged,
trail only machine. It's not tight like a sports car - it's rough,
tough, harsh, and noisy - the way it should be - or so I thought.
WOW - getting rd of the
old home-brew, unbalanced, "banana shaft" made a huge,
dramatic increase in how smooth and pleasant it was to drive. Sure,
you still get bugs in the teeth, can't hear yourself think over
the 350, and will never get confused and think you're in a Mercedes
- BUT - it is much smoother to operate now - both at trail speed,
and buzzing down the fire roads at 40mph. I'm truly amazed by this
- and very pleasantly supervised. Cool - thanks Jess!
For testing I wheeled
hard enough in this terrain......

And my new High Angle
Driveline shaft didn't flinch - not one bit!
So it's not only silky
smooth, but brutally strong too.
And take a look at this
series of shots below. Here I'm in 110:1 and with some pretty serious
rear suspension droop. I powered my way through, with no binding,
no breaking, no noise or carnage at all....and that's with my shaft
at 27* AT REST.
This shaft really is
all it is cracked up to be, and then some.
