Getting Started:
The 7500 DA’s are set from the factory at recommended starting settings for your application. They are pressurized and ready to go. The pressure setting is dependent on your application, drag, road race, short track , etc. This will be specified in your build sheet which you should receive with every Penske Shock.
Some basic tools you will need to adjust your new Penske 7500 DA shocks are:
1.) TL 73HSB Pin tool (for sweep style eyelets): to make rebound adjustments. 2.) Allen Key (5/32”): to make compression adjustments.
3.) Inflation Unit (TL COMPUNIT): to check and adjust pressure in shock. 4.) ¼” punch or pin: to make ride height adjustments to spring perch.
5.) Allen Key (3 mm): to secure ride height adjuster after setting ride height with springs.

To Set Ride Height:
Penske Racing Shocks does not set the spring preload on shocks that include coil over springs. You must set your ride height AFTER installing the shocks on the car. After your ride height is set, tighten the 2 Allen screws (3mm Allen) in the spring perch to prevent loosening. This does not need to be tightened too much – just nip up to prevent damage to the body threads.
