Joining the club

Hi All,
New member out of Idaho here. Picked up a 2008 TRD Sport DCLB and couldn't be happier about it. bought it used, 1 owner pickup with 105k miles on it. For starters i'll probably doing simple additions, WO set covers and upgrading audio. Long term i plan on changing out wheels and tires and eventually giving it a little armor. It currently has an all-pro leaf pack with timbren bumpstops in the back, and it looks like it's been lifted front and back but i'm unsure of what the components are up front. If the previous owner is on this forum i'd love to pick their brain a little just to familiarize myself with the upgrades. Side question, the timbrens appear to only have about an 1" to 1.25" gap between them and the frame. Is this standard? Does this have a substantial impact to uptravel, and if so, what would any of you recommend?

At any rate, happy to have joined the club and looking forward to hearing from this deep knowledge base.
