Ok Greg i hope this works, it looks like it costs a little more now. but this is what i bought https://www.ebay.com/itm/Weld-Triangulated-4-Link-Suspension-shown-Air-Ride-/371692274850?vxp=mtr&hash=item568a9604a2 It says suspension show air ride but there are no pads needed for the bags so i'm confused about that.

Youre going to bag it?

No Rob I'm using coil overs. That is why I was saying the ad talking about air ride. Because the kit I bought is not for air ride.

thumbs up that kit number shows set up for bags
You sure it has the correct lengths for the MGB and not some generic muscle car size?

I know the kit says it's for bags but it is not. There are no pieces in the kit that are made for bags. anyways as far as the rods go yes I do have to make them fit the mg. I already ground the welds off the one end so I can cut the tube to length then weld the end back on. I do not want to cut the tube in the middle then weld them back together. But for the savings in money I do not mind doing the work.

Just a suggestion, you might look into new weld in rod ends. Not very much $ and save you grinding and re welding a piece that was previously welded. Just shorten your rods and weld in new.

If you are wanting to do your own design and fabrication, then head over to Speeday motors and spend like $500 to buy everything you could need to do the job.

A lot of the value built into the CC kit is that it can be installed by anyone and the geometry, shock/spring specs and road manners have been dealt with.

If you build your own, chances are that the second you are done, you will be in the "Development" phase of the project, and that can and should eat up as much time as the design and fabricate phase.

As to the results when done, no higher praise can be put forth than the fact that the wife unit would go for rides and not complain every time the car went over a bump or railroad track. The GT rode like an actual car for a change rather than a self propelled buckboard.

Not saying you're wrong Pete, because you're not. The CCC kit is a good deal and the development is done. But on the other hand if you're keeping the shell fairly stock the geometry on the 4-link kind of sets itself. There's not much margin to move the links around and most of the DIY jobs I've seen all pretty much have the end of the bars in the same areas.

I don't drive my mgb much anymore, too busy running kids around every day. However, I drove it yesterday to get the fuel stabilizer mixed up and DANG - does this thing ride rougher or am I just getting old??? The leaf springs sure don't soak up the "choppy" bumps around town.

Not as easy as it sounds apparently. I recall when Bill's 4 link first came out there were some interference or binding issues which he quickly corrected. Makes a lot of sense to take advantage of that prior development work.

You are correct in that most of the link locations on a triangulated 4 link are going to define themselves. But god is in the details. What shock and spring combo to run? Adjust ride height with preload or shock body lenghts and give up travel? What rod ends you gonna run? What angle are you going to run on the top links? ( there are some close tolerances in a stock MGB) If doing this myself, I would not follow Bills U-bolt mount for the axle lower link/shock mount. I would design the mount and weld it on to the axle. Hopefully in the right place!

My life-long record is that I tend to get things working well by the second attempt and maybe need a third or fourth to perfect if I can be bothered. That is why I have never tried parachuting. ¯\_(ツ)_/¯

Reminds me, I need to figure out where the GT from Hell is...had some guy drive it off to a storage site and never asked where it was! Talk about "Out of sight out of mind"!

When doing your own rear suspension, spend some time reading. Pinion angle and roll center location is critical.
It makes a difference on how it will handle during acceleration, at the apex and out of the turn. Hard braking is also affected by the 4 link.

Not trying to discourage you, just get inform.

I have not driven an MGB with the frontline 4 (5) link rear suspension. I have two customers who took them out and replaced them with ours. Our kit shipping weight is 49 lbs.

I am shipping one to the UK to a magazine who will be doing an article on transforming an MGB and our 4 link will be one of the feature article. We have six 4 links in the UK.



It is our attitude that will determine the outcome

Thank you Bill, I respect your opinion but my problem is money. I am a disabled vet on a fixed income. so when I seen the price of this one I grabbed it. If I had the cash I would buy yours in a heart beat, Also on the positive side I love fabrication and building. After my last back surgery (4th) I got clean and sober and I needed something to do with my time that's when I started tinkering around with the mgb. I have always been a mechanic but fabricating I had no faith in my self, so I went for it and now 8yrs later I love it. And I have been reading about pinion angle but thanks for the tip on roll center location did not know about that. So now I will read about that. Thanks again Bill.

Congratulations, and I pray for your continued success. Although for some of us, our LBC's frequently drive us to drink

Bill- did your customer tell you why they were replacing the Frontline 4 links with one of yours? (I should note I have a box of parts that will be assembled into a CCE converging 4 link rear suspension for my MGC)

And what magazine is doing the article?

Bill, my two songs are vets, one a former Marine scout sniper, my youngest son is dual service, Army Special forces and became a USAF PJ also 100% teaching medical. I am also a vet dual service, so I do understand.

You can e-mail me or call if you have any questions. Glad to help you out.

Really don't like to put any product below ours. 80/20 rule applies satisfied 80% or better will like a product and 20% will not, numbers vary, but that is the way it works.

The magazine doing the article is Practical Performance Car Magazine in the UK.
