Heystee Parabolics

[east high]

Thanks, junkyddog11. This is the kind of firsthand feedback I was looking for. The RN parabolic kit is a pretty enticing when you throw in their occasional free shipping offers.

occasional free shipping offers.

The spring kits are not generally included in those offers - overweight.

Thanks for the input Matt (junkyddog11), just what I was hoping to hear. I just need to sell a couple of the Longboards to fund the new springs

Gah! I had a feeling...

I have installed the RN parabolics on many trucks, both the 3 leafs and 4. the 4 can carry a good load and are a good option for the LWB. the 3 leafs are a little soft for a 109 sw but would likely work well for a pick up that just carries people around. I have yet to see the helper spring on the 3 leafs get caught on anything. I suppose you could just pull them up toward the other leafs some how to prevent them getting caught up.

Heystee are the only way to go with the greasable bushings and Old Man Emu shocks. They rest of the parabolics on the market are questionable.

I have RMs on my IIA and have liked them, but they're due for replacement this year (I hope). I would love to hear reviews on the ones RN is selling, considering the chronic availability/support problems with RM.

Not saying much about the quality of RM springs, unless they have been on your truck for 30years and gone over 100k miles.

I have a set of parabolics from Rovers North on my '66 II-A for 3 years now. I am very pleased with them, whether under heavy loads [clearly woodlots], highway use or off roading. My Rover is run as both a safari top and as a softop. The shocks on the car are Old Man Emu's.

My other II-A still has the original Land Rover springs. You can sure feel the difference in operation, less on smooth roads than on bumpy or dirt roads.

My IIA Station Wagon was fitted with 2-leaf (front and rear) RMs in 2002. The light-duty 2 leaf setup was chosen for maximum axle articulation and it has performed well, but now has gotten tired and sags under the weight of camping gear, dogs, spare fuel, etc. all added to the heavy tropical top with roof rack. So, I'm planning on replacing the springs with a 2-leaf/3-leaf setup; a little less flexible but better for the loaded weight of my rig. Its worth noting that RM does not recommend the setup I have for the configuration of my truck because of the issue I'm experiencing. Just not sure who's springs to use (leaning towards RNs units).

Best regards, Andrew

FWIW, the Rovers North ones have the helper spring on them. At least thats what they told me a few months back.

I bought a set of RN parabolics a few months back, and the 3rd leaf is part of the same spring "pack" - it definitely is not a 'helper' type leaf. IIRC, the 3rd leaf does sit slightly farther away from the other 2 leafs, but the ends contact the leaf above.

Long term, greased polybushes really aren't that great (although they will offer a slightly higher degree of resistance free movement) but will wear out faster than plain old rubber bushes, a fact not missed by working truck fleets world wide. They are significantly easier to change, which is good as you will need to change them fairly frequently (depending on operating conditions) unless the wandering truck syndrome is tolerable.

.....trying to temp me with the boards again?


one other note about the Rocky Mtn spring is that they use an odd size bushing. Not that big a deal as they are of a very high quality and wear well....just a PITA to find (and they manufacturers seldom seem to have any)

[junkyddog11]

....yup. I spend much time messing with springs, and not just Rover springs.

[CliftonRover]

I bought poly bushes for a classic and the rear ones failed almost immediately. they were torn to pieces, I replaced with the genuine ones. the leaf bushings are different but it was still clearly a sub-par material for my application

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.

as with everything on the market there are different manufacturers of the same looking part, some are good and some are not.
