Hi, what longer dampers can I reasonably buy for my pick-up? the existing ones (as bought with vehicle) are 440 long and the springs when unloaded are 445 mm centre of bolt to mounting. so to get them on a fat bloke has to jump on the back to compress the spring to 440.
the springs are standard multi-leaf and the shackles are at 45 degrees .
It is undrivable as the back skips and bounces all over the place.
ideas???

I had exactly the same problem with my 109, although it runs on parabolic springs. I used some pro-comp dampers [link below] to allow the suspension some rebound travel. I also used some balata belting to make up some longer axle straps, although I don't think they are strictly necessary.

Thanks, mine has the eye fitting at both ends- But the SWB rear pro-comp extended should fit- do you think there is any reason not to use SWB on LWB?

thanks- interesting reading--- why did LR make the dampers near the end of travel- I have about 40-50 mm between axle and bump stop-so 200+mm of travel is wasted.........

As long as the damper is secure, and has some rebound travel, then, I think you'll notice a considerable improvement in ride quality. There isn't need for much rebound travel from the static unladen position, because you need most of the travel to allow for loading the vehicle up and then some extra bump travel beyond that. Phrased another way, it would be a waste of damper travel to set the damper up mid-travel when the vehicle is unladen. The situation is similar, but less extereme, when dealing with ordinary cars where the difference between unladen and laden is not as severe.
