I really had to dig through the info on extreme terrain's crappy webstore, but it appears these shocks are part numbers 60046 and 60048. OME offers two different valving options for TJs, and these are the softer riding of the two. I believe that's a wise choice if going with the OME shocks.
Regarding bump stops, the front shock is the same closed length as a stock shock, so no additional bump stop is required there. However, the rear shock's closed length is about 1" longer than the stock shock, so you will need a 1" - 1.25" bump stop extension. To get precise, you would have to pull the springs with the shocks in place, compress the suspension until the shocks bottom, and measure the gap between the lower perch and upper bump stop cup.
Thank you. Your part #s look correct. Extreme terrain is terrible about listing these manufacture part #s. In lieu of a 1” bump stop extension, could I add a hockey puck to the axel side?
