    Arthur gets new (parabolic) spring in his step

    G'day everyone..

    After reading about how parabolic springs are next nearest thing to riding on clouds, Arthur now has been upgraded with a set of Britpart parabolics.

    Whilst I've only driven around town so far, they do seem to feel more supple and I reckon cornering has improved a lot. Being a SWB there is still plenty of bounce in the ride, but its feels more 'wavy' now

    The test for me will be how much better badly corrugated roads go.

    I'd be interested to hear in any tips and tricks in how to get them to work best.

    Like any spring, they will work to their optimum with a decent shock. You dont say whether you changed these as well. A longer travel shock would be in order, as parabolics give greater articulation.

    When we put parabolics on our Stage 1, they were bought as a set with shocks, although I wasn't that fussed with the ones supplied.

    Yep, sorry I forgot to mention I have a set of new heavy duty "Tough Dog"s all round. I put them for our last trip with the old springs (the old shocks were dead).

    I also kept the rebound straps on the back, which I replaced not long ago. The old ones were broke off years ago (before I got Arthur).

    Hi Landydude,

    I have also recently put a set of Britpart parabolics on my Game and while they ride well I have a problem with a lean to the drivers side. I was wondering if you have the same issue or if yours sits level? I have swapped the rears from one side to the other and it still leans to the drivers side so I am thinking it is something to do with the car rather than the springs unless it is just a fact of life with the parabolics as they are not different side to side like the standards.

    Thanks,

    TimJ.

    Funny you should mention that. On my old springs I had a lean to the drivers side of about 2" (simple measure from the ground to the top of the rear wheel arches). I had put that down to the old springs.

    But with my new ones I still reckon there is a bit of a lean. I was going to get around for a bit, let them settle in, and then and measure it properly in various places and see if its real or my imagination.

    I wonder how much this might have to do with the fuel tank also being on the drivers side. I have also modified mine, changing the 10gal tank to a 16 gal tank.

    All Series Landrovers have a weight bias to the right - fuel tank, transfer case, battery, steering gear, and usually driver. For this reason all RH factory springs have more set on them to get them to sit level. However, they usually sag to the right anyway eventually. But if the parabolics are not handed, they must give a lean to the right.

    Ah I never figured the springs would be handed! I didn't see any difference between the two rears, (but wasn't looking either), so I think I should have a better look and make sure they have the same part number of have some differentiating markings. I'd hate to have to swap them over though. Took me a few hours to fit them trying to get everthing to line up (especially the locator pin on the dif). I did it all in the home garage with a couple of jacks.

    Dont think the parabolics are handed. When fitted, you should do all bolts up lightly, take the vehicle for a short drive, allowing everything to find it's comfort zone and then tighten them all up.

    Two jacks and a pair of axle stands are the go for fitting/removing springs. Mine were Rocky Mountain springs.
