Truxxx 1.250" Rear spacer does not fit!

^^^ Who has installed Daystar DT09100BK on a 5th gen w/ 5.0" rear bumpstop? Any troubles? Just got mine but ID only measures about 4 7/8". Not sure if it will squeeze in there with the weight of the truck or what (press fit). Piecing together my lift and would prefer to get it installed in one shot.

Update: It Fits!

Installed one of these last night to check fit and although things did not nest together just sitting on the bench, after putting a little weight on it everything pressed together nicely. Full install is next weekend with a set of Firestone Coil-Rite air bags and Bilstein 5100s for the front
