Yes, but it is modified stock. 7300/3100 is "stone stock". . .the only things open on the suspension are the shocks. Everything else stays stock without reinforcement. No fiberglass, etc.
7100 can run fiberglass fenders/bedsides, no bed, reinforced pivot points, uniballs and aftermarket rearends. Essentially, they go a little faster, but they are a LOT more durable. On paper.
How much less would you worry if you could plate you lower arms and run uni-balls? Oh yeah, I almost forgot, " beef up those uprights". Keep everything else the same for while. Run the same pace and not stop to replace front end parts. You just now ran the same times as a 7100/7s (on average).
Preachin' to the choir Mr. B. . .preacin' to the choir. Heck, just beefing up the lower arms and uprights would solve 98% of the issues we have at our current pace. In fact, if we just could beef up our passenger side upright. . .we'd be Golden!!!
