Gemmer boxes for Morgans up to the early 1980s have now been reproduced through Morgan Motors of New England/Morgan Spares. RHD available in 30 days with LHD coming in 60 days or sooner.

A little late for my Plus 4. I managed to find and fit a good used one just over a year ago. What a difference it makes to the steering - so positive now especially as I had a steering damper fitted at the same time. Money well spent...!

This is fantastic news for all owners of older cars. Not only those whose car was fitted with a Gemmer originally , but also those who have the Cam Gears/Burman boxes who can convert to this much improved upgrade.

In so many ways, the Gemmer is a better upgrade than going to Rack and Pinion, and one that I would heartily recommend.

Thank you very much indeed Linda and Larry for investing in this for the benefit of older Morgan owners.

This is very good news.

I bought off someone in France last year a specially made for racing rack and pinion to fit a 70s LHD 4/4. For those of you who like technical details it uses a rack from an Opel 1900GT. I planned to install this at some point in the future when I convert my car from RHD to LHD.

I'm therefore interested and intrigued by Mog 615's post that perhaps Gemmer is better than rack and pinion. More info would be appreciated.

Cheers

A 1970s car would be fitted with the Burman/Cam Gears box originally. The Gemma is almost a drop in replacement with little re-engineering. That alone is a major plus but for me there is an even more important benefit.

The Gemmer box retains the same geometry as the original with the drop arm, and long steering links. This gives rise to less "bump steer" than the very short steering arms on most rack and pinion set-ups. It also gives excellent steering "feel" and feedback ( better even than a rack in my opinion)

The main reason for fitting an r & p is to ease steering effort at slow speeds, the Gemmer box does this also , the only way for you to compare would be to drive a r & p equipped car and compare it to a Gemmer system.

Andy

Thank you for the explanation.

Given I've already got the racing r&p, I'll install it first (when i eventually get around to the conversion). Nevertheless very good o know that alternative now available. I was a very frustrated '78 +8 owner who could do little, without vast expense, to improve his very heavy worm and peg steering.

Cheers

Philip

My 4/4 had a Gemmer and it was great for steering. I wouldn’t worry abouta car with one and no need to upgrade to R&P. Just keep an eye on the ball joints on the steering link rods.

Run a Gemmer/Gemma since the early 1990s on the +8. No problems and a definite improvement over the original. Managed to source a new one in 2015 along with a new Salisbury diff.

I second that as excellent news. My 1980 Plus eight is a bit "vague" after 240,000 miles and this would seem an excellent option.
Have registered my interest.
