    i replaced my old rear springs with proline standard leafs.Left side went in fine.I bent the right one while installing it so I ordered another at my cost and now installed that one.It still seems to sag a little. I think the quality of steel used is a big factor.I liked the price but im wondering if they bend that easily whats gonna happen on the trail loaded with camping gear?

        How the hell did you bend a leaf spring? Do you mean that you permenantly changed the bend in it, or you just compressed it and it sprang back?

        I have never permenantly bent a leaf spring, that wouldn't sit well with me.

          Now back to the thread.

          My parabolics on the 88" are from British Steel (purchased from Paddock's). I have had no problems out of them. They installed fine and have not affected my driveshafts thus far.

          Wallace,

          I hate to say this, but you must have installed something wrong. There are only two other explanations if you didn't. 1. One of your new springs is badly bent (which should be fairly easy to spot). or 2. Your frame is badly bent (which should be easy to spot).

          As for the rear tires being more to one side, can you measure this? How much to one side? Take a measurement to the brake drum on each side (not the tire). It is possible that one wheel has a different offset than the others and maybe you never noticed.

            I've got RM parabolics installed by the PO and there doesn't seem to be any problem to date. Try switching the rear springs and see if that make any difference. As far as the driveshaft noise goes, you may very well have been facing U-joint problems and the parabolics just brought them out.

              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.

                I really like Rovers North and their parts quality has always been high HOWEVER, I have yet to hear anything good about there parabolic spings. I too almost got hooked into the cheaper shipping, but decided to hold off. If you cant get a straight answer from them, you should return the springs.

                  This issue of springs "bending" has gotten my attention as I am about to buy 2 sets for my projects.....If a spring is soft enough to bend , it has to be really inferior quality steel, or perhaps made in 3rd world shops.. anybody see The New York Times last week, where the manhole covers for Manhatten were being cast in a foundry in India? Front page with photos..Sadly, a lot of our parts are being made in these primitive sweat shops.. I guess I better do some research before moving onward........
                  I spent most of my money on women & cars, the rest of it I just wasted.......

                    Price is soon forgotten quality is not!


                    With all the headaches some of you have been having I would be happy to pay an extra $200 more to for go the headaches. So the question now is who builds the absolute best Parabolic springs?

                      Are these guys high quality? I really like there Front Disc brake conversions and the Power steering unit. I would also like to go with Parabolic springs since you loose so much unsprung weight Or should I say Sprung weight. Anyway. I just wanted to hear if these guys are top notch or not. Thanks.

                        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...

                          I have Rovers North parabolics - not from Rocky Mtn. Love 'em.

                          Put them on a year ago - no problems. In fact, I just took of the Old Man Emu shocks (too stiff for me) and reinstalled the Woodheads - love the cushy ride and find the handling to be fine.

                            I have had the RM parabolics for 6 months and have found them to be good and no problem with fit.

                              I'll put in another vote for RM springs. I've had them on for about 6 years now and I've never had a problem. I have a hardtop on my '71 88 and run the 2 leaf up front and 3 leaf rears. She rides nicely and handles with the best of them. I went with the Rancho shocks. With the RM set up you need the longer shocks as the Woodheads are too short and will top out.

                              Mind you I was just considering that Ray has had good business out of me. I was looking at my 88 and so far it has RM:
                              - Parabolic springs and Rancho shocks
                              - Spin on oil filter adapter.
                              - Transfer case bottom plate.
                              - Roverdrive.

                              When Ray gets the new doors sorted I will probably spring for a set of those too.

                              Cheers

                                They are awesome. I, too, will get his galvanized door bottoms when available.
