Parabolic installation issues...

[PH4]

RM is getting ready to produce Galvinzed door bottoms? Great news.

Ray has been working on them on and off for quite a while.

He told me he got a small shipment once but wasn't happy enough with them to get a production run. I call him every so often and annoy him about it - would love to have them up here in Salt-Land.

hmm, makes me think about my method. lets see.

with a trolley jack under the frame, jack up the end of the car you are working on until the wheel is off the ground.
support the frame with a BIG jackstand. repeat on the other side.

now you should have the tires off the ground and the frame securely resting on jackstands. i.e., the suspension is @ rest, not extended or compressed.

remove road wheels.

choose a side to work on and support that side of the axle with a jack but don't lift it.

undo the spring u bolts.

undo the shocks if necessary

undo the spring eye bolts as nec.

install the new spring fixed eye, then the shackle end. put the bolts through but only loosely. this should put the center bolt in about the same spot as the old one, you will need to jockey the axle a bit to make the holes line up. install u bolts, double check the center bolt alignment and tighten the ubolts up.

this method eliminates all the risks of installing and removing springs under compression. I know there are other ways to do it but this si the one that has worked the best for me in all the ways I have done it.

Of course it isn't that often so sometimes I forget.

HTH,

I bent it by jacking the spring up to the axel which was on jack stands.I place the pumpjack in between the axel and spring mount-jacked it up about 3 inches to the axel.Put on my ubolts and shock plate-tightened all the nuts-released the jack and there it was- a nice crimp in the spring.So i ordered another one thinking that It was my fault for bending it.So i tried again with a new one. This time I placed the pumpjack as close to shock plate as possible but still allowing me to get the ubolts and nuts on.Jacked it up less this time to the axel ,about an inch, which was on jack stands.Tightened everything up.Released jack.Noticed slight sag but not as bad as the first time.Truck is still a little tilted.

Im happy to say that I spoke to mark at RN and they think maybe I got a bad batch of proline springs.So they are sending me some genuine ones and taking back the prolines.Great support.Thankyou RN

Well after reading this thread I'm getting a little nervous. I received my springs a little over a week ago after a 2-month wait. the springs arrived the day after I left for a business trip to Dubai, go figure (my poor wife had to carry them to the garage for me). and now I can't install them until after the new year. I really hope they're not part of the bad batch 'cause it looks like I'll be beyond the 30-day return period. has anyone else had issues with this latest shipment of parabolics?

[ctrover]

mine were regular springs,not parabolics

[SHORLAND]

those look pretty good, as do the disc conversions. (though not sure how those stack up against Timm's)

it sure does hurt to buy stuff from europe right now though. I onder what a set of springs + shipping would set me back...

Who is TIMM? Sorry for being such a noob!

Who is TIMM? Sorry for being such a noob!

no worries man i haven't really been around here that long either. Timm Cooper is the guy i was talking about. supposed to be pretty amazing rover guy. RN used to sell his disc conversions a few years back

here's a great thread, with pics. the guy at the top of the thread is now the go-between for the conversion kits
