2" Tera Spacers + Rancho 9000XL's

Hey everyone,
I installed the 2" teraflex coil spacer lift. I've been running this with stock shocks (with the bumpstop extensions included in the lift).

I've been unhappy with the ride, so I'm upgrading shocks to the Rancho 9000XL's. When I ordered them I specified I had a 2" lift. Looks like the Rancho 9000XL's they are shipping me call for a 2.5" lift.

So a few questions... Is this going to be an issue? Don't want the shocks to be over compressed, but keep telling myself 0.5" probably isn't that big a deal.

2nd question. Will I need to make any bumpstop adjustments vs what the kit came with?

Thanks

Step by step:
1. what are the shock part numbers front and rear? find those, then look up the compressed shock length with google (or measure it yourself).
2. Now measure how much bumpstop extension was installed with your lift.
3. Now, for every increase in shock length over stock you need a proportional increase in bumpstop extension to prevent the shocks from overcompressing. Stock rear shocks are 12.25" compressed length, stock front shocks are 13" compressed length. So, if your new front shocks are 14.5" compressed length, you need about 1.5" bumpstop extension. For reference, with a BB, the rear bumpstop extensions need to be the same height as the spacer...so this will likely be the determining factor in your case.

Thanks for the response.

2.5-in. W/rancho RS6503
Front:RS999239 (Compressed 14.64")
Rear:RS999241 (Compressed 13.69")

Bump stop extensions that came with kit are 1.5" front 2" rear

Think I'm golden?

I guess the question is; do I need to extend my front bumpstops 0.14"? ((14.64 - 13)- 1.5)?

Really rather not damage these baby's but don't want to do unnecessary work either....
