Hey, So i'm starting my build Tomorrow! Its going to be purely trail driven, not really looking to daily it at all, mostly just dolly or trailer it to the trails! My question is that I got a 3in bds leafs and 3in iro springs, and want to order 4in 5100's. I would bumpstop accordingly and ive heard of people doing this to increase downward travel. From what I understand it would limit upward travel slightly but if bumpstoped correctly it could have benefits on the rocks.. Any input?? Thank you!!

Excessive down travel is over rated. Up travel on the trail is a beautiful thing, being able to move around without riding on your bump stops. Besides, unless you're upgrading everything in your front end you could be limited by the control arms, steering, etc

I agree 100% although I got a good deal on a pair of 5100's "3.5 to 4in" shocks.. Me being just over 3in in total lift, would a .5in to 1in longer shock really hurt my uptravel that much to where i'm riding on bump stops? Thank you for your reply!!

No one else with thoughts?

I've never bought shocks for a certain lift height. I usually just measure the suspension travel and buy shocks accordingly. If you've already got the shocks then I say run what you brung and adjust later if necessary

I dont have them yet but my buddie has a pair brand new for sale.. hmmm. How do you measure the suspension travel Im very curious as that sounds 10x more accurate!! Thank you for your advice!

If your buddy had a new set for sale then you need to adj. price for that fact and tell him so, they aren't the exact size needed and you may have to modify yours. That affects the sale price.
