I have received and installed CV axles, and the elan
is a much better car.
Compliments. Ib Nielsen from Denmark

Hi Col,
I made it, thanks to your drive shafts, to the all British
Day which was held at the Uraidla Oval in the Adelaide Hills.
Having now fitted them, I have to say I'm not sorry the not
so old rotoflex coupling let go, as the car is now transformed.
I'm delighted with the way it is running and today it was very
well received. It is great fun to drive. ,

Thanks for your assistance.
Wayne M. Adelaide. South Australia.

Dear Col,

We finished our elan restoration, we have travelled 7000 miles
(11265.41KMS). We are very satisfied with the CV Drive Shaft
which you sold us.
We gave your address and phone number
to a friend who has elan too, who is very interested
in your parts.

Best regards.
André & Ghislaine Prosdocimo.

Hi Col.
Finally, last week end, I could go for a long drive and the
feel of the elan is fantastic. My brother said: The elan
like a modern car! No one will say it is from 1966!!

Really, your drive shafts are really good. They transform
driving of the car. They are not only fantastic as
a mechanical component, but they are also beautifull
to look at. They are also very easy to fit, and all was
done in a couple of hours.
All the best.
Francisco F.
Cascais. Portugal.

I hope that you keep producing the quality product that
you do. You and your firm have been a pleasure to deal
with even if you are on the other side of the globe. If
you want a test pilot for anything new you're developing,
I'd be happy to road test it.

Thanks again for a fantastic product.
Harald Freise.

Hi Col,
I thought you might like to know how the CV drive shafts
are performing now that I have some mileage with them.
They certainly have transformed the driving experience
of my Plus 2, and smooth gear changes are now easily
Unlike the ones fitted to my car when I bought it,
your drive shafts show no tendency to “bind,” even when
the suspension is at full droop, which shows the benefit
of using quality components.

They also look the part with a nice finish to the machine
work; pity they have to be hidden under the car!
I can certainly recommend them to any Elan owner
who needs to upgrade the driveline on his car.

Kind regards,
Wylie Evans. New Zealand.


G'day Col.
The drive-shafts are fitted and performing well. The CV
drive shafts are performing exactly as you promised -
much quieter than the strange thumping that occasionally
came from the doughnuts - but two of those were fairly well
stuffed. The elan now drives much better out of the corners,
and has a much more positive feel all over - well worth the
B. Nibbs. ACT. Australia.


Dear Mr. Croucher.
Thank you very much. My mechanic says that your kit is
the best in the market followed by Spyder´s. I guess I will
have to save for yours (I am a teacher).
Thank you again.
Carlos. TN 37240. USA.


Hi Colin,
I can definitely vouch for your CV conversion, the quality of
build, as  well as it's durability. It was a good fit, easy to
install,  and has been (still is) trouble free as stated on
your website.
It's a truly 'fit and forget' conversion.
B. Chan. Singapore.


"I have used the solid CV joint drive shaft conversion on
my Elan S4 and Plus 2 for many years. The Plus 2 has
covered about 40,000 miles of every day road use, and the
elan has done about 15000 miles of race use with the
conversion with absolutely no problems. From a strength,
reliability, cost and ease of maintenance & driveability view
point the double CV joint conversion is far superior to the
original donuts and other designs I have seen using
universal joints or CV's in a combination with donuts".
Rohan Hodges.
Melbourne Australia.


I've just installed a CV kit from Croucher Engineering Aust
(elantrikbits) and am absolutely delighted with the result -
so much tighter, there's no binding of the CVs and the
+2 drives so much smoother with better gear changes
and a more robust feel overall. I'll keep the Roto flexs
and shafts but, if anyone is wondering whether the CVs
are worth it, you are unlikely to look back.
thanks for your help Col)
Best regards.
S. O'Dea. Sydney Australia.


After experiencing donut failure in an S1 elan many
years ago, I fitted your CV conversion to my
S2/26.4204. I am now fitting your front adj upper
wishbones, and can thoroughly recommend the quality
and engineering of your products.

Regards. Billyt. NSW. Australia.
P.S. I think it should be mandatory for any elan used for
track work to use your C.V. drive shaft conversion.


After having consulted with Col regarding the manufacture
and materials used in his drive shafts, I installed them
into my 1964 S2 Élan around one year ago. On receiving
them, I was very impressed by the quality, finish and
details, such as the dust caps, grease points and high
tensile bolts. After fitting, I have found them to perform
very well, being very positive in use compared to the
rubber donuts and eliminating surge particularly on
take-off. As my "donuts" were getting quite old, I now
don't have a fear of a dangerous failure.

I would recommend the drive shafts to any one considering
them for their Elan, particularly if they use their car
in a spirited fashion!

Why install CV drive shafts?... the answer is simple: Total Driveline Reliability.

It is a well known fact that the new generation of rubber donuts do not deliver long term reliability, once a reasonable mileage had been covered, the rubber donuts are prone to failure without warning! (Some have failed in less than 500KM) You don't want that happening! 

How’s Yer Donuts?… Not Looking Good?
Maybe it's time to purchase and install a CV drive shaft conversion into your elan. Your drive shaft conversion is delivered fully assembled & ready to install, a competent elan owner/mechanic will easily complete the installation in a lazy afternoon, in fact as one of our customers recently discovered, it will probably take you longer to remove the old donuts and half shafts than it will to install the elantrikbits CV conversion.

Can The CV Drive Shaft Installation Be Reversed?
Absolutely, the elantrikbits drive shaft design is a bolt up arrangement, you do not replace the diff output shaft nor the outboard wheel hub shaft, unless of course you discover that they are damaged or worn in some way. While reading through our install instruction sheet, elan owners are instructed to keep & store the original old donuts and the intermediate shafts. The CV drive shaft assembly can also be removed if required and the old system can be re-installed again without any problems what so ever. Not that you would ever want to do that after you experience the driving transformation of your elan with the new CV drive system, but you may one day sell your elan, the new owner will appreciate having the original parts included with car.
