anyone ever tried these (looks dangerous)

http://www.speedwaymotors.com/p/6907,368_Clamp-On-Leaf-Spring-Pad.html

I saw these while looking through the speedway website. This would be great because i don't have a capable welder for ch***is work but this also looks incredibly dangerous. i'm hoping for some positive feedback because i want to swap the rear end on my 54 plymouth to get rid of those overly-difficult brakes, but i don't want to use this product if it's going to break or be unsafe. i'm sure i could find a buddy with a good welder if it doesn't work out but was curious on feedback for this product.

so anyone used it?

 

I can't see that being a good idea at all.

 

Come to terms that the yoke of your rear end will be in the p***enger compartment soon.....along with spinning bits of drive shaft....

 

That's a "floating" mount--it's designed to be used with ladder-bar or leaf-link suspensions that have two forward pick-up mounting points (leaf spring eye and ladder bar mount), and allows the axle to rotate slightly as the suspension goes through its range of motion.

If you put it on a car with only one mounting point (like just a leaf spring), the rear end housing will rotate as you put the power to it, and you'll end up with the pinion yoke pointing up at the floor board and the front yoke pulled out of the back of the transmission.
It'll be a mess.

They are about the same price as a pair of Moroso pads
http://www.jegs.com/p/Moroso/763126/10002/-1/10141 You can get them through most local parts houses though.
The only advantage I see for the speed way ones is that you could set the pinion angle a little easier in some cases. From reading their description I think that most guys would still weld them to the axle.

 

you need to use a welder to install you new rear end. get spring pads like mr48 said , set pinion angle and measure for center....then find someone who can weld

 

I find it irresponsible, of Speedway to sell these. Don't use them, they are not right.

 

It is designed to be used with leaf springs and U-bolts,,,there is a nut on top where you drill into the axle housing and it is clamped to the axle tube.

Careful mesurements are a must for pinion angle.

I have seen them on a car with a lotta miles with no problem,,,used correctly,,I can't see a problem.

I have a welder,,so I can't see me ever having a need for them,,HRP

 

That has to be the CHEAPEST piece of **** ive seen in a long time.

Just another Junk part available thru catalogues to cause Failure to unedjucated buyers .

 

It's a RACE CAR part, there are countless stock cars plying the dirt tracks with that form of suspension attachment, of one form or another, every Sat. night.

 

This may be true, But this part looks like a CHEAP CHINESE piece of **** !!!

 

Now that's funny right there I don't care who ya are...

 

That is circle track part that is designed to be clamped in place to set the rear end up. Once the correct pinion angle is established, a couple of good tack welds is all that is needed to hold it in place. They are designed for a true 3" O.D. rear end tube like a floater 9" and probably wouldn't fit on a regular p***enger car housing. I have used them for years with no problems including clamp on brake caliper mounts, and three and four link mounts. When they are tight, they will not move, the tack welds make it a bulletproof connection.

 

Ok, the way this works is you drill a hole in the axle housing and then there is a bolt that threads through the nut on top and into the hole. you then attach it by u bolts and the other mouting plate. it's not just the clamp.

I called speedway and asked their tech people what they had heard about these and he said they sold 550 of them in the past year and he didn't have a single one of them come back. He said they haven't had any complaints either. That's why i posted this, to see if anyone is using them and what their experiance has been.

I think i'm just going to take my axle to my buddies house and weld up the normal moroso perches but i thought this was a pretty interesting product. I also thought it looked really dangerous, lol.

 

I'm not familiar with circle track stuff. Could you enlighten me as to what the difference is between the normal 3" p***enger car housing and the 9" floater you were talking about. thanks.

 

Looks ok to me.. I think where the nut is you prolly dont drill thru the axle tube but put a good spot in the tube then set a bolt in there to lock it at the proper angle.. Dangerous ? Prolly not .. Cheap ? maybe maybe not..

A 3" O.D. housing will have an O.D. that is exactly 3" in diameter, not 2.90", or 2.875". The clamp on bracket are designed to clamp on to an exact 3" O.D. tube.

 

yep thats a race car piece. not for DOT use fellas. Now if you full weld it thats another story.

Kinda like brakelines. I trust the nylon ones with my life offroad, but they just are not built for the day in day out life of a daily driver.

I wouldn't hessitate to use that to set up a rearend, and then weld it down. Or drive it to someone to weld.

 

yes

 

With this item you can set the pinion angle a hell of a lot eaiser than the Moroso
item..then just weld away..Duh!

 

That's probably what i'll do. a buddy of mine has a good 220 MIG at his house i can use to get it securly in place. thanks for the info fellas.

 

Read the description on Speedway's web page. It's listed as a street rod piece, not a race piece. Grade 5 hardware, looks way too lightweight and only 2 3/8 bolts keeping the housing from rotating. Imaging what a sticky set of tires and a 4 speed would do to this setup. If you're gonna weld it on, just get the Moroso saddles and be done.

 

550 sold and not a complaint... on the road fatality. No one to call.

 

This is a circle track part that's used for an adjustable rear suspension and it's NOT sold for use on a street driven car. There are a lot of oval track suspension pieces that are adustable or adaptable for changing track conditions that are encountered at different tracks that a compe***or might encounter. IT'S A RACING PART, NOT A STREET PART.

Possible that people who know how to spell UNEDUCATED would know that and try to guide those who inquire. I think the fact that it's advertised in a RACING catalog might give one the first clue as to it's application.
BTW, this particular item is used with axle anti-rotational devices such as ladder bars or ******* bars letting you move the spring inboard and outboard to fine tune the spring rate and/or mount the spring to clear other objects that might be tempoarily mounted to maximize the handling of the ch***is.
Then there is that whole Mig welding thing, A subject for another time.

ok if its a street car part then whats the deal with this tech tip



and i wouldnt use it but i buy weld on perches at fleet farm

 

For the un-informed:

The bolts that actually clamp the part to the rear end housing are 1/2".

There are also clamp on panhard bar mounts:

Clamp on spring/shock mounts:

...and clamp on brake caliper mounts:

Once clamped in position, and after a couple of good welds at least 1" long, they are good to go. Since when were race parts not allowed on the street? Most street parts originated on the race track in the first place. These parts are bolt on just like most everything else on our cars, they are designed to carry the loads. What make these brackets any worse than a set of conventional leaf spring pads that Welder Joe goobers on with his trusty whatever kind of welder? There is more than one way to skin a cat.

 

Those are roundy-round parts, gang. not fer Your shoebox.

 

sko_ford. This tech tip does not apply to the clamp on spring pads. It applies to Speedway part number 910-43320 which is a lowering block with an adjustable pin that allows you to change the wheelbase on the car from side to side and tighten it, or loosen it, on roundy-round cars.

I don't understand what you mean by this comment.
