Suspension tuning

[agent orange]

Now that my rig is finally 100% on the mechanicals and maintanance (well, minus the new radiator in the mail), im gonna spend some time getting my suspension dialed in. My goal has been to be able to have enough clearance to get my tire to tuck with the axle on the stock bumpstop (or at least close). Once i take a torch to my wheel wells ill post up how my fender trimming worked out, but so far im pretty darn close to my goal. My only issue is that last time i was out wheeling i noticed that at full stuff my front springs are reversing their arch. Ive seen this happen on a lot of built rigs flexing, but im wondering if it would be best to extend the bumpstops so that the stop uptravel at the point where the spring is completely dearched. Im sure it would cost me some uptravel, but id rather not wear my springs out unduly quickly. What do you guys think?

just extend your bump stops...


what wheels are you running that you need to cut out your fenders?
- my brother runs 37's on his 60 without a prob. (SOA)


i think you will regret cutting out your fenders in the event you ever do a spring over...and if it is travel your looking for its SOA you want.. i'm not trying to change what you've done just shooting some ideas out to ya.

I'm asking a question so this might be a highjack...why not use antiinversion shackles to stop the spring problem?

I have anti-inversion shackles, but they have nothing to do with what im talking about. The shackles extend forward like they are supposed to under compression, im saying that the spring flattens out under compression and then continues to compress, reversing its arch.

Bandy rooster, the fenders are done been cut. In hindsight i could have done a little cleaner job if i had taken the time to finally learn how to weld, but its nothing a little sheetmetal work wont solve when i get the skills. I just kinda cut a chunk out of the outer and inner fender where the fender was cutting into the tire. Im just gonna have to form a patch panel to fill the hole and then it will look sweet, i like the way the trimming turned out from a side view, just not the hole on the inside. Plus, a tree already has fallen on my rig, so im already working with a ugly but functional asthetic.

But to get back to my point, should i go play around with a forklift and extend the bumpstops so that uptravel stops right before the tire starts rubbing the inner fender (my original plan, utilizing the most possible travel), or should i extend the bumpstops further so that the spring never reverses its arch (and in so doing lose compression travel that i know i have)?

Bumpity bump.

Cmon, let em reverse their arch or not?

ha! mine are so worn out that the rear spring have been inverted for months. I have new springs they are just sitting in a pile with the other stuff i have not put on yet. The inverted springs ride nice;p
