Lol sorry fellas, was too excited to put them in, but diameter wise they're about the same without measuring. For what its worth to my eyes the SVT's looked slightly larger diameter but it could have been the piggy back making it seem that way. Overall the SVT's were beefier feeling for sure and about 2x heavier than the Elkas. I was able to compress the Elkas with my bodyweight to install them originally, but with the SVT's I was forced to use the ratchet strap method.
Rebound wise they are just like everyone else said, composed on big dips with quick settling (This is with about 400lbs in the bed, carry about 600-700 full loaded on overlanding trips). It feels closer to how my 4Runner feels with Dobinsons. I actually had to lower my airbag PSI to 20psi to make it less bouncy.
Unfortunately my impression of the ride is going to be skewed because one of the Elka's was blown in the rear with no oil leakage and I was probably overcompensating with 50psi on the bags. When I took out the lower bolt I was completely surprised it didnt extend, so it explains the issues I was experiencing leading me to hunt for new shocks. Im a little disapointed because I have only about 4000 miles on this Tremor since its reserved only for offroading, and maybe about 3000 of those miles were highway/offroad with the Elkas.
Honestly if someone is hunting for new shocks strictly for offroad/overlanding/southwest desert I wouldnt recommend Elkas, and thats not considering the bad shock. I feel like they were valved more for the street than the rocky southwest.
