Bilstein 5100 installation on 2in BB

Hello,

Im going to be installing a daystar 2in bb and bilstein 5100 shocks. I was wondering if anyone that has installed these shocks had to do any modifications on the rear bolt and bushing sleeve to prevent clunking. I hear alot about aftermarket shock bushings not fitting the bolt snug enough on the wj.

Thanks,

Scott

Re: Bilstein 5100 installation on 2in BB

When I upgraded to Bilstien HD's I changed out the bolts and torqued them down really well. All I did was order some 10.9 Hex Cap Screw 12MM-1.75x70 from Fastenal. I've got some clunking, but I'm pretty sure that it's not the shocks, and instead the rear upper ball joint that needs to be replaced.

Re: Bilstein 5100 installation on 2in BB

I am going to get new bolts as well. Did the shock fit snug in the mount after torqued? Like all the way to rubber bushing? I know I have read some had to add washers to prevent back and forth movement of the shock in the mount. Maybe it was on the older shocks and hopefully they are more of a direct fit now. I should know in s few days when they arrive, been waiting over a month for them, they have been on back order. Must be a popular shock!

Re: Bilstein 5100 installation on 2in BB

I actually installed the bolt before the shock went on and tightened it a bit to tighten up that gap a bit. They did fit snugly, I remember having to convince them a little to get them in. Actually I compressed the shock while bolted on the bottom and allowed it to expand into the pocket where it mounts on the top.
As far as popularity...at least on this forum, Bilstien is a very popular brand among WJ and WK'ers. The ride difference was like night and day. My stockers had about 70k on them. When these went on it felt so much better and was soooooo much less bouncy.

Re: Bilstein 5100 installation on 2in BB

Well I finally got it all together and all I can say is WOW! What a difference! I love the ride with the 2in BB and bilstein shocks, feels awesome! The bridgestone dueler revo 2's 255/70/17 fit perfect. No rubbing or bumper trimming needed but this is a daily driver no wheeling. I can't say they wouldn't if flexing out the suspension. Everything feels so tight and quiet better then when I bought her at 20,000 miles. I had some nasty clunking with the mx6 shocks that had 50k on them but all that is gone. Changed out the stock shock bolts. Those shocks were toast after 50k. Completely rusted. The bilsteins definitely feel better then the pro comp mx6 ever did. It been a long time waiting for the shocks but well worth the results. I also installed the jks adjustable track bar. I ordered everything through Kolak. Great guy to deal with!

Question though, I took it for a front end alignment after I did all the work and firestone said that the camber and caster adjustment is slightly off do to the lift and cannot be adjusted. Is something I need to be concerned about? I dont want these new tires to wear out prematurly. The jeeps rides perfectly straight no tracking at all. Just wondering if anyone else with a 2in budget boost had this issue.

Thanks,

Scott

Re: Bilstein 5100 installation on 2in BB

Congrats on completing the upgrade. I'm a big fan of the Bilstein shocks as well. I have the HD's with no lift as I do mostly mountain highway driving and no offroad. After one winter season with plenty of snow in the Sierras, not a spec of rust on the shocks and the "handling" on the Jeep has been transformed. They are fantastic.

I'll be watching for any answers to this one also - I just finished the same lift two weeks ago. My front Bilsteins (for 2" lift) came yesterday and the rears are backordered. Picking up my wheels and tires this afternoon... anticipating anxious moments with front tires. The wheels I chose had a little more offset than I'd like and I'm hoping they're going to clear. I don't really want to start messing with inner fender modifications, etc. I'll post again tomorrow after my interesting evening!

You will love the shocks! What size tire are you going to run? Did you go with the 2in daystar lift over upcountry springs?

Re: Bilstein 5100 installation on 2in BB

Oooh! I want to know the answers too! I'm set on some Bilstein HDs but was worried about the bushings/bolts. That seems to have been answered. Now just wondering if I should get up country springs or the 2" BB. Will be upgrading to 17" wheels and new tires later this year. Want to go as big as possible without any rubbing/trimming.

Will you be using it for wheeling or more as a daily driver? I can say anything bigger then 255/70/17 would probably rub slightly
