HighlandRover Posted October 31, 2009 Share Posted October 31, 2009 Hi Im about to build a challenge truck with a 3" lift and am at the stage of ordering all of the essentials. My question is, What radius arms do people recommend? I could go for the obvious QT 3 degree castor corrected arms but I have heard a few people with bad things to say about these such as not being strong enough and poor fabrication? Would appreciate everyones thoughts on the subject. Also I have the gywn lewis challenge suspension kit, will 3 degrees of castor corrected-ness be sufficient? Cheers Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 31, 2009 Share Posted October 31, 2009 If it's *just* a challenge truck, why bother with caster correction? Quote Link to comment Share on other sites More sharing options...
HighlandRover Posted October 31, 2009 Author Share Posted October 31, 2009 If it's *just* a challenge truck, why bother with caster correction? When I say challenge truck I also meant to say daily drive aswell ( until I break it that is ) Is there no need for castor correction on a challenge truck? Sorry if its a stupid question but its my first build so there will be a few more to follow I think Quote Link to comment Share on other sites More sharing options...
bishbosh Posted October 31, 2009 Share Posted October 31, 2009 Not answering your question , but why the 3" lift? I would stick with genuine arms and live with the castor issue or speak to Gwyn Lewis and get some genuine ones adjusted to suit your intended lift.

Yeh I know, 3" isn't ideal but I aquired the springs and propshafts on the cheap so due to a limited budget im just gonna stick with them for the time being! I take it Gwyn Lewis still adjusts your arms? Any ruff guesses what he charges for the service? Quote Link to comment Share on other sites More sharing options...
ex_mod_90 Posted October 31, 2009 Share Posted October 31, 2009 No such thing as a stupid question I used to use my challenge truck as a daily drive, 2" lift with 35" Simex. I didnt bother with castor corrected arms and never missed them. In general most people I know have found that they caused more problems than they solved. As others have said you cant beat the genuine article. They are alot stronger than after market items. Trailing arms yes, they should be cranked to take the strain off the chassis bushes. Buy good quality items, I use Gwyn Lewis, and they are pretty much indestructible! Rich. Quote Link to comment Share on other sites More sharing options...

gsr341 Posted October 31, 2009 Share Posted October 31, 2009 are you sure your springs are +3" gwyns kit (as fitted to my truck) is only +2" im using standard arms with no problems at all , still on original bushes 2 years on . alternatvly Gwyn can ''bend'' your original arms to add castor correction , much stronger option . p.s make sure you use genuine trailing arm chassis bushes or you will be for ever replacing the dam things Quote Link to comment Share on other sites More sharing options...

I'll maybe give Gwyn Lewis a call when I return to the UK about bending the arms. Quote Link to comment Share on other sites More sharing options...

m&mv80 Posted October 31, 2009 Share Posted October 31, 2009 anyone know how he bends them? i guess heat them up first then bend to required angle, if so does this affect there strength? Quote Link to comment Share on other sites More sharing options...
ajh Posted November 1, 2009 Share Posted November 1, 2009 Why would you bend the arms rather than re-indexing the swivel balls to correct the castor? Quote Link to comment Share on other sites More sharing options...
redneck Posted November 1, 2009 Share Posted November 1, 2009 Why would you bend the arms rather than re-indexing the swivel balls to correct the castor? Because it`s cheaper to have the wrong pinion angle, have more vibration and replace UJ's/propshafts more often!!!!!!!!!!!! Must be the right way to do it, as everyone else does it????????????????????? Quote Link to comment Share on other sites More sharing options...
andyb Posted November 2, 2009 Share Posted November 2, 2009 anyone know how he bends them? i guess heat them up first then bend to required angle, if so does this affect there strength? I have put S bends and banana shapes into standard front radius arms just by hitting trees, so I can't see how adding bends is a good idea Quote Link to comment Share on other sites More sharing options...
m&mv80 Posted November 2, 2009 Share Posted November 2, 2009 I have put S bends and banana shapes into standard front radius arms just by hitting trees, so I can't see how adding bends is a good idea exactly, i can see how relieving stress on the chassis bushes is a good idea but im not so sure bending a std radius arm is the best way to go about it Quote Link to comment Share on other sites More sharing options...
