Trying to replace my stock steering rack on my '77 in order to get quicker steering.
I THOUGHT that Moss only sold the quicker rack versions now, but after speaking with them, they don't think that is true. They believe that the only racks they currently sell are direct replacements for the stock racks and therefore have the same steering ratio as stock. (Quick for CB cars, slower for RBBs)
Moss Europe lists the late model quick rack as "No longer available".
Anyone know of a solution to my problem?

I wonder how much the steering effort goes up?
BTW, there is someone who makes racks for kit cars. Seems like one of their racks was a quicker rack based on a MGB rack. Been a few years since I stumbled on their website.
Maybe?

My

Lighter,quicker
But not made for rbb years.
You can always swap in an cbb crossmember and rack
Lower it at the same time.
I assume you want quicker for Solo2/autocross?

Yes, I am aware that steering effort will increase. Rob has it right... I'm autocrossing and the existing steering ratio is...well...it keeps me busy!
Crossmember conversion seems like a lot of work but maybe the answer. A lot of research needed there...

Brad,
Quaife lists a fast rack for the MGC , but I don't know if it's compatible or if it can be modified.
https://shop.quaife.co.uk/mgc-lhd-quaife-quick-rack-and-pinion-kit-2-9
Now... changing the steering rack for something with a quicker ratio is... not allowed under the "if we don't say you can... you can't rule" So, the question is, if you're going to make changes then go big or go home.
Speedway makes a 2:1 quickener. I think what you trade off is number of turns for strength to turn the wheel.

But if you front the 2:1 quickener with electric power steering... you might have the best of both worlds. Some assembly required!

Received the rack and pinion today. While I'm very impressed that Moss Europe can deliver parts to me faster than Moss California...I am disappointed to discover that the part is not really designed for late model MGs.
As you experts know, one difference between the new/old steering pinion is the length. The other is the design of the end that connects to the U-joint. In both length and end design, this quick pinion is the older type. Whomever makes this part figures they could make a single part work for both early and late racks by supplying an additional U-joint to make up for the differences.
They also provide no instructions for how they might recommend dealing with the above. It looks like they expect to install this by having two U-joints in a row, connected by some piece they didn't give me. I may have to consider cutting this quick pinion and welding it to a piece of late model pinion to address both of the flaws in this part.
Is welding a steering pinion something that can be safely done? (By an expert)

Define "expert" - I would guess that the steering gear is hardened and heat treated.
I would not trust my life on it even in the hands of an "expert." - It's not just about making a pretty weld.
The goal - Reliable summer driver interspersed with mechanical tinkering...
Motto - "Driving fifty in the twisties..."
On Mods - It's your damn car - Do what you want. Haters gonna hate...
On SUVs - Drive your B like a soccer mom is texting her friends about how she wants to kill you...

I have saved parts from British cars for over 45 years & there were some, very few 2.5 turn L to L R/B steering racks that were made & I have 4 of them!
It is installed!!!! Thanks Glen...2.5 turns lock to lock as promised. Also, having another rack and pinion to look at makes me realize that the MOSS Europe supplied quick pinion was for a RH drive car! That part was wrong on many levels. If I cared enough I would tell them.
A lot of time spent measuring to ensure my steering wheel was straight in the middle of the rack travel and that I kept my toe In unchanged..that was the most difficult part of the install. A lot of thinking about doing stuff and not actually doing anything,
I have yet to fill it with oil, so no test driving until the weekend. I'm somewhat frightened.
