series3_mad Posted November 2, 2005 Share Posted November 2, 2005 i gto some procomp es3000 shocks to go with my new rocky mountian paras but wat way dose the shock go, is it so the damper rod is at the top or is it at the bottom. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 2, 2005 Share Posted November 2, 2005 Rod up. Quote Link to comment Share on other sites More sharing options...
Tonk Posted November 3, 2005 Share Posted November 3, 2005 small rod (shiny chrome bit) upwards, body (bigger white bit) downwards. Quote Link to comment Share on other sites More sharing options...
Jon White Posted November 3, 2005 Share Posted November 3, 2005 And whatever you do do not fit the rubber boots cause they fill up with mud and make the shafts go rusty. They're far better without them! Jon Quote Link to comment Share on other sites More sharing options...

02GF74 Posted November 3, 2005 Share Posted November 3, 2005 I thought it didn't matter? Wouldn't the better design have been for the body to be attached to the chasis reducing unsprung weight? (critical in a LR!) Quote Link to comment Share on other sites More sharing options...
Tonk Posted November 3, 2005 Share Posted November 3, 2005 which way up did lr fit the body of the shock as standard? (dont answer cos i already know) Quote Link to comment Share on other sites More sharing options...
ltwt1981 Posted November 3, 2005 Share Posted November 3, 2005 Not that I will do this, but why can't you fit gas shocks upside down. With oil I guess they may leak but gas will leak either way up. Just thinking out of the box. Quote Link to comment Share on other sites More sharing options...
Tonk Posted November 3, 2005 Share Posted November 3, 2005 i did hear somewhere that procomps /can/ be fitted either way up, but why would u want/need to? Quote Link to comment Share on other sites More sharing options...
ltwt1981 Posted November 3, 2005 Share Posted November 3, 2005 I don't but theres always one! Quote Link to comment Share on other sites More sharing options...

02GF74 Posted November 3, 2005 Share Posted November 3, 2005 i did hear somewhere that procomps /can/ be fitted either way up, but why would u want/need to? less unsprung weight? Quote Link to comment Share on other sites More sharing options...
Tonk Posted November 3, 2005 Share Posted November 3, 2005 i really can see it makin any diffence TBH. would it actually less unsprung weight? Quote Link to comment Share on other sites More sharing options...
minivin Posted November 3, 2005 Share Posted November 3, 2005 i really can see it makin any diffence TBH. would it actually less unsprung weight? on a coilie it would be comparable to comparing convention motorbike forks to Up Side Down (USD) forks, just that the springs are on the outside rather than on the inside Quote Link to comment Share on other sites More sharing options...
02GF74 Posted November 3, 2005 Share Posted November 3, 2005 i really can see it makin any diffence TBH. would it actually less unsprung weight? gggrrrrrrr.... I knew someone would say that! Q. was why would you want to, I gave reason. I didn't say it would make a big difference so I'm with you on that point, maybe up to 1 or 2 kg? which when compared to weight of everything else axle/tyres is not that mcuh but if you are a top competitor and looking for every little advantage.... yes - (I think). Surely even with a leafer, bolting more mass to the axle will increase the unsprung weight regardless of whether it is a damper body or brake disc????

Tonk Posted November 3, 2005 Share Posted November 3, 2005 brake disc?????? where did that come from? i think my brake disc conversion is probably lighter than a drum set up (no, i'm not takin them off to weigh them). i agree that less unsprung weight is an advantage but if all the weight is at the top of vehicle with feather weight axles then on a side slope u would roll easier Quote Link to comment Share on other sites More sharing options...
02GF74 Posted November 3, 2005 Share Posted November 3, 2005 brake disc??????where did that come from? This came from me nosing round on kit car forums where there was disccusion about the merits of rear disc vs drums regarding performance, weight, complexity, handbrake etc. So as not to keep you in suspense, the drums came out lighter, performance between the 2 was neglibile as most braking being done by the front; handbrake arrangement simpler and better.

Tonk Posted November 3, 2005 Share Posted November 3, 2005 alot of weight differences must depend on wot drum (lr must be much heavier than normal car) and wot disc it is replaced with, alloy calipers etc Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 3, 2005 Share Posted November 3, 2005 If I remember correctly, even gas shocks contain oil hence benefit from being mounted the right way up. Will have to dig up the PPC article... Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted November 3, 2005 Share Posted November 3, 2005 Jons comment re boots is true, as such if you fit the shocks upside down (ie canister at the top), the mud water and rubbish will leak out of the boots as they are lower and gravity will do its thing. There is also the reduction of COG to take into account, fitting a 4 shocks canister down means the weight is lower down and therefore better of road as less able to roll over, to get the best of both worls how about fitting them alternately on each axle ? inok actually do shocks speacially made to be fitted cylinder side up I'll get me coat Nige Quote Link to comment Share on other sites More sharing options...
Les Henson Posted November 4, 2005 Share Posted November 4, 2005 There's also the more obvious reason why you don't fit them upside down - if the body of the shock gets a bit bashed the shock will still work probably, but if the rod gets damaged, the shock will leak or even break. Just common sense really. Some gas shocks do indeed contain oil as well. This is done to better graduate the performance of the unit. Les.

LR90 Posted November 4, 2005 Share Posted November 4, 2005 The consensus seems to be that boots are a bad thing. I could see the merit in this arguement and have left the boots off of mine. However, the pitting on the fornt side of the shaft, is now very obvious on mine and will I'm sure lead to rust / seal failure in due course. A boot would have prevented this. I for one am now wondering if the boot might not be the better idea afterall? Quote Link to comment Share on other sites More sharing options...
series3_mad Posted November 6, 2005 Author Share Posted November 6, 2005 Well i finished putting my springs on yeasterday only got front shocks coz when i went to get a full set bearmach said they didnt have the back shocks so got to wait for them now Quote Link to comment Share on other sites More sharing options...
Tonk Posted November 7, 2005 Share Posted November 7, 2005 the boots just fill up with mud and keep it all wet in there, personally i wouldn't fit them Quote Link to comment Share on other sites More sharing options...
series3_mad Posted November 7, 2005 Author Share Posted November 7, 2005 i havent fitted the boots. mud+water+metal= rush Quote Link to comment Share on other sites More sharing options...
