If you're looking to save money, get the Toytec Boss Aluma Series. Exact same shocks with different branding. Elka makes them.
Resi's will help keep the oil cooler in your shocks, helping to reduce shock fade. If you offroad over fast sections or for extended lengths of time, resi's will be beneficial. If you don't, don't worry about getting them.
I've been looking at both of these, and try as I might, I don't see anything on the Toytec site that compares with these from Elka:
2.5 IFP FRONT & REAR SHOCKS KIT for TOYOTA 4RUNNER, 2010 to 2020 (with KDSS) (0 in. to 2 in. lift) >> Elka Suspension Inc
This configuration is for use with stock geometry and can accommodate 0 in. to 2 in. of lift with either stock or aftermarket upper control arms.
Everything I've found on the Toytec Aluma Series is 2"-3" of lift...it could be I just don't know where to look. If the Aluma Series had something comparable, I think I might just go with those...not everyone wants to start at 2" of lift.
