I've been reviewing the HAMB sites with regards to installing '70 to '87 (XJ, XJ6, XJ12, XJS, XJ4.2, XJ5.3) Jaguar front suspension.
Wheel Track (58" on Jag & 59.5" on Roadmaster) and weight (3200 - 3600lbs on Jags & estimated 3600 - 3800lbs on my Roadmaster setup) seem to be a good match.
- One local hot rod shop says this is old technology and recommends a Heidts or Speedway Mustang II.
- They also say it will cost more overall to use the Jag parts & be hard to find parts for in the future.
- I have not had luck finding reliability info on these years of Jaguars.
1) Does anyone else have direct experience with these Jag suspensions who can speak to these issues?
2) I'm also considering a rear end and suspension from these Jags. Does anyone have experience with install, and reliability of jag rear ends?
The ideal situation would be someone who has installed both.
Thanks

Here's some added info for my previous post.
Here are shortcuts to the installation of Jag suspensions on a '57 Buick:

and a '53 F100 truck.
http://www.jalopyjournal.com/forum/s...d.php?t=571296
1) What does everyone think of the integrity these conversions.
2) Would you recommend that I pursue this approach on my '37 Buick Roadmaster,or use a with Heidts Mustang II front and Ford 9" rear.
Thanks

I've been following this thread as I have a '41 Poncho that, I believe, has the same suspension.

Another way: 2" drop spindles (from CPP), replace springs with bags, remove lever action shocks with relocated modern shocks. Easier approach than fabbing or piecing together your front end?

Thanks for the feedback.

1) Do you have disc brakes now?

2) Do you still have king pins?

3) What tires & wheels dia & width are you running?

4) Can you tell me the exact parts you used for the air bags and modern shocks?

5) What is the height of your running boards at front and back?

Pictures of your shock setup would be helpfull too.

Thanks

Sorry, but I haven't started. With the bags, the height will be whatever you want to make of it (within reason).

Wheels tires are 16" 6.5" (wide whites!)

This is the bag "kit" I have: D2500/D2600# bags, 480 comp, 5 gallon tank, digital ride control.

http://shop.airliftcompany.com/produ...ed_air_springs

Front will likely get spindles (FF for ~2.5" drop). I may see about flipping the existing spindles and see if that will work. Looks like I may be able to swap and reverse sides to get ~2-3" drop.
Another idea is to push the A-arm an 1", that should get the same result.

Fab upper/lower shock mounts. I'll snap pics what is planned when I have the front back off.

Scarebird type setup for discs.

I also have a complete '02 Mustang rear assembly (w/discs!). That will get the 4-link treatment.

That Mustang year is basically the same weight within 100# (and rear width) of my Ponti -I'll likely start with stock front and rear shocks.

My Pops has a similar setup on his '51 Buick. Rides just fine.

Thanks again for the info

Your approach sounds like it might work well.
My car has a stock oil filled shock absorber.
One local restoration shop that recommended:
- keep coils springs as is and use the existing IFS
- leave that oil shock on, but disable it and fill it with grease
- weld on some mount pads for a new shock absorber
- swap out spindles and add disc brakes on front
- install sway bar

Hot rods shops around here all recommend replacing front susp. with a Heidts , or equivalent, Musdtang II front susp. set-up but this is pretty pricey for parts and install. Can't help but think they are trying to optimized their $$$.

Still waiting to hear from someone who first optimized standard running gear and then swapped out for Mustang II. I would like to know just how much of a difference this makes in the handling of a big and heavy car.

I will be doing a MII in my 52 Canadian Pontiac which is the same frame as a 52 Chevy.
There is a place where you can buy the MII cross member as a you weld kit. It is called the Welder Series.
I then plan on using stock MII control arms and spindles from Speedway.

I have not found any other way of using stock spindles or control arms other than a front clip off a vehicle. The MII is the best for my vehicle IMHO.

Thanks for the feedback.

If your goal is to add front disc brakes to your '52 Pontiac, you can buy a conversion kit from:
http://www.scarebird.com/index.php?id=1
That kit provides the conversion kit and list of parts that work with it.
You may also want to check out Classic Performance Products:
http://www.classicperform.com/
Classic performance also has drop spindles.

If your goal is to add ball joints & rack&pinion, then many have recommended the Heidts or Speedway Mustang II kits. These are higher cost than the Welder Series, but the these cross members are welded together to a greater degree than the Welder Series. If you are confident in your welding capabilities, the Welder Series may be the way to go. One thing to consider is that ordering the whole kit from one outfit will eliminate fit issues that may arise.

Can't speak with experience on what is the best approach, because I'm still sorting out the options myself.
Thanks

Thaks for the feedback.
1) Have you installed a Heidts of Speedway Mustang II susp & brake kit with no problem?
2) Could you estimate the time required to weld together the Welder Series cross member.
3) Would you happen to know what thickness the metal is on the Welder series?
4) Does anyone know how this compares to the Heidt cross member thickness?

Hey Mutt whats with the 1 2 3... stuff! Man I thought I was back a school!

Your best bet on these questions is to contact Horton's and ask them. They have excellent videos on the assembly of each of their products.
I know they have been in business for over 40 years and have sold there stuff all over the world. It is a family owned business and an icon in Canadian Hot Rodding. They have thousands of satisfied customers, and I am happy with their product which I have used for over 30 years!

welder series ?

Welder series stuff for the most part is weld it yourself and save the bucks. they have excellent instructions for setting up any suspension and a lot of good Utube videos you can watch. the Mustang II kit comes. flat the parts are laser cut and you fold them, the connection points act like hinges,
