The Triumph Dolomite Club - Discussion Forum

Hello everybody

I was just reading in the book Haynes "Owner manual" for Triumph Dolomite 1972-1981 / 1854cc and Sprint about Rear Anti Rolling Bar. Also I read in the blogs here, that it isn't special necessary to have them! I have a Dolly 1973, 1854cc,
comm.n° WF 10WF10247.
Can anybody give a tip what must to have or not!!

And what about the rear shock absorber: I want to put GAZ GP 6 2267 / 2268 series for front is this correct?

Thanks in advance for your answer, I wish every one healthy time

All 1850 and Sprint Dolomites will have anti-roll bars both front and back as standard. The front bar is essential for safe control of the car. At the back it can be seen bolted to the suspension arms and to the floor in front of the axle. Do you need one? Well, the car will drive OK if you take it off but why would you? Its there for a reason - to prevent too much body roll on fast corners. Personally I would leave it alone.

I believe some of the serious race guys remove the rear one only.
Bearing in mind the springs are set ultra hard.
Far too hard for road use.

I would leave them well alone for road use.

If it's missing, and you need one, I have spares...

To everybody thanks for your answers, I don't want to change any thing, I was only confused about the different reading in the blogs!!
I wish you all a good time and good sunday

PS: I don't need any spear parts, my Dolly has one in front and rear!!

Are you sure about that? I am pretty sure it is just bolted the the suspension arms.

Ive taken mine out to be powder coated,and it was only bolted to the rear suspension arms

I believe some pre Sprint 1850s went without the rear ARB and certainly the vast majority of OHV cars weren't fitted with one until near the end of production, when I think 1500HL and SE got them. AFAIK the Toledo is alone in the range in not having a front ARB.

In all cases, the fittings are there to retrofit ARBs at both ends.

The actual purpose of the rear ARB is harder to define. Certainly the factory thought it was a necessary upgrade for the high performing Sprint, at least in street trim. The factory race cars, with altered spring and shocker rates and LSDs seemed to perform better without the rear bar, they had a token bar made out of something akin to piano wire to keep the car compliant with regulations. If the street car had one, the race car had to have one too!

But there is a world of difference between Joe blogs putting the hammer down a bit on the odd roundabout in his stock 127hp Sprint and Gerry Marshall pounding round a circuit in a race car with 220 horse on tap, lifting the inside front wheel and throwing the tail out on corners!

My instinct says the rear ARB fitted car is stabler and more predictable for people with (no offence intended or implied) only moderate skills, the more advanced driver will probably like it better without, being more confident in controlled oversteer!

But it's very much a personal choice, some people prefer with and some without. If you dont push the car hard, you probably wouldn't be able to tell the difference! Having said that, I've kept the rear bar on both my highly modified cars. I tried both ways on the Carledo and it seemed marginally more predictable on or near the limit with one fitted. But I LIKE "point and squirt" over the more dramatic Roger Clark "sideways everywhere" style, so I've kept it in place and the one on the Dolomega too. This may change when it comes to actually driving it, you can't really say till you've given it a good test both ways, it's only a few minutes and 4 bolts after all!

My P reg 1500tc auto hasn't got front or rear fitted and never had them.

I have two late 1500HLs, one 1980 and the other 1981 reg cars and they do not have rear ARBs.

Whoops. That shows that at my age you shouldn't rely on your memory. It isn't bolted to the floor as I thought it was. I've just checked in the parts book!

Hello all

sorry to answer only know, but we know the "circontances" we are!! Thanks very much for all comments. I will fellow the advise: driving with rear ARB. ( I'm not racing at all, more sundays-trip on portugues roads!!)

Healthy time
