Heystee Parabolics

[luckyjoe]

I wouldn't compare Classic poly bushing to Series greasable polys - similar material but entirely different animals. I'd never use poly on a Coiler (Classic), but I'm seriously considering them next round on my Series.

There was as good thread on them if you search...

Last time I talked to the makers of the Rocky Mountain Parabolics, they told me that Rovers North is buying their springs from them and re-badging them as their own. Unfortunately, up here in Western Canada, the Rocky Mountain springs seem to have a bad reputation. I know quite a few owners who have had nothing but problems with sagging/leaning issues.

After careful consideration, I decided to spend the extra and buy the Heystee Parabolics. Unfortunately, I am now dealing with a warranty issue with them, as in less then 10 000kms I have developed a very heavy lean to the left! That being said, Paul Heystee has been absolutely incredible to deal with! He appears to offer a level of customer service and pride in his product that you do not see very often. Disregarding the lean, the springs w/ome shocks, offer an incredible ride and articulation. I do believe my problems may be a limited occurence, as other clubmembers have been running the Heystee/TIConsole springs for years under heavy abuse and have reported no problems at all.


fwiw

I talked to Mark at Wise Owl Parts today, they are ordering some of the Heystee springs as well as some of the other products Heystee makes.

A while back RN was supplying RM parabolics. Not any more. The parabolics I received a few month back from RN were definitely not RMs.

I have had my truck for over 18 years and have tried pretty much everything on the market for it at one time or another and I can say with much confidence based on experience that the greasable poly bushes have already outlasted the original LR bushes by far.

funny that there is always somone who gets results that are off the normal charts. Congrats to you.

Usefull info would be;

If you want maintainence free bomb proof forget about it average performance, and count your pennies...use a quality bound (standard) bushing.

If you want slightly better performance, don't mind the maintainence, are capable of changing them, don't mind spending the extra $$....get some greasable polybushes.

Not sure if it is a matter of location and or useage but I run both and have a pretty good barometer of the differences in them and that it is mostely as described above a matter of what you want to get out of them and what you are willing to do to get that.

As for springs. Haystee is definately a quality product. Only had one set fail to date and those were on a Toyota B70.

Some of the less expensive English sold brands are bloody awfull.

Have yet to have any Rocky Mountain springs perform satifactorily and their customer service is (I have found) not the best. Odd sized bushings.

That was a useful way of summarizing. Now the engineer in me would have to point out that to make your last statement of any real value you would have to qusalify what satisfactory performance means to you.
- Durability?
- Ease of installation?
- Articulation?

Interesting.

After this quote from Mr Letorney in explaining why RN is reluctant to disclose their vendor sources.

"......It is extremely important for us to have the ability to change manufacturers smoothly when quality or availability issues surface w/o being subject to false advertising, or bait and switch......

Respectfully,
Mark Letorney".

And in light of this from catalog, which appears to have been printed 4 years ago, and continued to this date (online catalog):

"After years of testing, research and selling four different types of parabolic springs from around the world, we’ve determined these (emphasis mine) to be the best available."

"These" (the "best available") may be a moving target.

Kind regards, Josh

junkydogg would also have to qualify what he considers "off the normal charts" to be. I am not the first person to use and be happy with the greaseable bushings, in fact I am probably part of the majority to be happy with them and have postive results-to each his own I guess, but the normal charts from what I have seen, is greater longevity and performance from the greaseables. I guess we need to define what normal is. Having OEM bushings fail in less than 3 years and 15k miles is not "maintenance free and bombproof " in my book.

Years ago there were definitely some crappy "oem" bushings out there and people had early failures. However I've had a new set of OEM's in one of my trucks for 12 years and ~85,000 miles without having them fail. I was going to replace them this past summer but there really was no point as they were still all good- it was a pleasant surprise.

It appears to be one of those YMMV things.

In this case satisfactory performance would be consistant rates or springs that couldn't be installed without the vehicle leaning fairly severely (more that 3/4") to one side or the other.

It would seem that the majority of people....myself included .....are very happy with polybushes. Most of that same group would also agree that they do not last as long as a quality bound bushing. The poor lifespan you have experienced with bound bushes probably has something more to do with the quality of the bush and or the installation than the type of bushing used.

I knew I'd read where the current RN para's were coming from but took my while to dig it up, from Dec. '07. I believe Woodhead is in India.

Gentlemen,
Its been brought to my attention that some customers think we are hiding the source of our parabolic springs, because when they ask who they are made by you are telling them that you do not know. This is clearly my fault for not telling you, it was just easier to ID them by color. The manufacturer's name is Woodhead. As you know we have made a steady progress w/ manufactures and quality since the early days, and even just recently reevaluated Woodhead against another new manufacturer. They are awesome springs.We have sold hundreds of trouble free sets. This does not mean we will always sell Woodhead, because if we find better you can be assured thats what we will switch to. As you know, our goal is have our ProLine parts represent the best in quality. This is one of the reason for developing our own brand name. Unfortunately it looks like it can be interpreted negatively by prospective customers not familiar w/us. I'm not sure how to correct this, and would appreciate any comments to help build confidence w/ new customers. Thanks,m
