Pre-Assembly
If you want to have your shocks, collars, springs and perches all assembled and ready to install on the car, we do offer that as an option.
Not all pre-assebly is the same. Simply sliding the threaded coil over kit over the shock is not what we are doing here. There is a big difference between simply assembly and race prep of the suspension kit.
Choose from the drop down list below to purchase a pre-assembled version of the suspension kit. What does the pre-assembled version get me?
- NB Shock Hats - Modified to accept the Penske shock.
- Spring Isolator - We beadblast the shock hat spacer and the 99 shock hat to help them handle glue a little better, and then glue the shock hat spacer to the shock hat so that it can not move.
- Installed Penske Bump Stop Kit - We properly modify the OEM Shock hat per the installation instructions and then install them into the OEM hat and onto the shock with the spring.
- Springs - We then assemble the entire package with properly positioining the spring on the perch relative to the perch, threaded collar and relation to the corner of the car that it lives on.
Your pre-assembled suspension kit will come to you all put together so that all you have to do is install each shock assembly on each corner of the car and you are done.
If you have a 1990-1997 model car and will be doing the suspensin kit assembly yourself, you will need to update your shock hats to the 1999-2005 style. You can add those to the drop down list from the menu. These would only be needed for 1990-1997 model vehicles.
If you want to add some of the Mazda OEM suspension cam bolts choose form the drop down list. Price is for (1) Bolt, (1) Washer and (1) Nut.
