How To: Oem SRT8 Bilsteins and Bwoodys Springs

Well these are some pics about the installation of rear suspension of my 06 jeep commander 5.7 hemi limited with OEM SRT8 Bilsteins and Bwoodys Springs (with upgraded bump stop from energy suspension)

Heres a look of the ingredients.

1 Set of Shocks




1 Set of spring (pic oem vs bwoodys)




1 Set of upgrade bump stops (pic oem vs energy suspension)



One side at time.

Fisrt raise the jeep, and secure it with a pair of jack stands, dont put the stands below the axle, use some chasis parts, we need that the axle gets down to release the springs.

Support the the bone that holds the brake caliper and the mass with a hydraulic jack, to hold the axle and get everything under control.

Second remove the bolt of the swar bar (19mm) that goes to the wall of the chasis (in this step is helpful have the axle at normal position with the help of the hydraulic jack, to make the bolt comes out easly).



Third lower the most possible the knuckle but have always the hydraulic jack support it,then when u can move the spring with your hands, its time to remove the oem bump stop, u can use two screw drivers to pop up that yellow gromet, or a small pry bar, then theres a bolt (15mm) that attach a metal cup to the chasis, remove it and know take out the oem spring.




Then just remove the shock, having the axle the most lowest possible to easly remove the stock lower bolt (upper and lower bolts are 15mm).

Fourth place the new bump stop inside the metal cup, theres a small washer that needs to go between them, try to use some energy suspension transparent grease, is useful grease all the gromets that have contact with metal.



Then screw the cup with the new bumpstop to the chasis, with the supplied bolt its a (8mm allen). Dont know how much torque but keep it tight, i also use permatex red locker in hall bolts.



Fifth, install the bwoody spring it can fit with out problem with the bump stop already installed, if not try to lower more the axle, and next install the bilstein shock, you can use the hydraulic jack to line up the holes and insert the bolts with out problem, also for the swar bar bolt. Tight them and torque the shock bolts to 80 ft/lbs and the swar bar bolt to 90 ft/lbs.




Install the wheel and lower the jeep. Here are some pics about the results:







Rear Stock 33 1/2 inchs
Lower Springs 31 inchs

2 1/2 inch lowest...

Re: How To: Oem SRT8 Bilsteins and Bwoodys Springs

Doesn't look like much up travel left even with the shorter bump stops. Are you often hitting them and getting a harsher ride?

They have nothing to do with the hardness of the suspension, because the car is a lot lower.
