Mustang Strut 2011/2012 Introduction: Thank you for your purchase of your new Penske Racing Shocks Mustang package! The Mustang package can be used in all forms of racing. This manual will explain the details of the strut, give torque specifications, and give all part #’s.
Mustang Strut 2011/2012 Terminology: INFLATION VALVE SPING RETAINER TL-COMPUNIT IS THE REQUIRED TOOL TO CHECK AND FILL PRESSURE AVAILABLE FOR 2.25” OR 2.5” SPRINGS INNER TUBE SWAY BAR MOUNT BOLT SPING PRELOAD ADJUSTER TORQUE TO 30 FT/LBS AVAILABLE FOR 2.25” OR 2.
Mustang Strut 2011/2012 Getting Started: The Mustang Struts are set from the factory at recommended starting settings for your application. They are pressurized and ready to go. The starting pressure for the Mustang Strut is will range from 75-225 psi, depending on application. Adjusters: The most popular and common adjuster are the dual-bleed adjusters, these are nested within the same mechanism. This means that when making a compression adjustment, the rebound adjuster will NOT turn.
Mustang Strut 2011/2012 To adjust, follow the procedure as follows (if this procedure is not followed in the recommended sequence, the intended settings may not be achieved in practice): To Set Adjusters: 1.) Turn REBOUND full clockwise until it stops. 2.) Turn COMPRESSION full clockwise until it stops. 3.) Turn the COMPRESSION counterclockwise to desired setting. 4.) Turn the REBOUND counterclockwise to desired setting. 5.
Mustang Strut 2011/2012 Adjustment Range: COMPRESSION (20 Clicks) The adjustment range of the compression adjuster works primarily in the low-speed area of the velocity spectrum. This is from 0-2 in/sec in strut velocity. Testing has shown that this is the area where transients to the chassis can be tuned depending on driver preference and down-track aero performance. These adjusters are very driver sensitive, so 2 clicks, sometimes 1 click driver will feel. LF LF LF LF LF CD+ C-15 R-15.cvp CD+ C-20 R-20.
Mustang Strut 2011/2012 Disassembly Procedure: This is a brief explanation of how to disassemble your strut unit so you can service and or re-valve you strut. 1. Remove lower mount. 2. Remove Dual Bleed Adjuster Knob assembly. a. Do this by turning rebound knob counter clockwise unit entire assembly (a) is unthreaded. b. **a small steel washer and aluminum plug (b) should be with adjuster assembly** (a) (b) 3. Clamp outer tube into TL-BDCL-MUSTANG-OUTER (c).
Mustang Strut 2011/2012 4. Remove inner tube assembly from outer tube by pulling inner tube out. 5. Depressurize tube assembly at this point. Remove valve cap from inflation unit (e) and depress valve core. (e) 6. Hold inner tube assembly in vise using flats on body cap or using inner body clamp. Then using the proper spanner wrench (f), unthread the shaft bearing (g) from the inner body. Before removing shaft assembly from body, install TL-45RNG (h) to capture any oil overflow.
Mustang Strut 2011/2012 7. You are then ready to remove the Ring Nut from the shaft. Hold the shaft in the TL-SH-CLAMP (i), and with a ¾” socket, remove the nut. You can then make changes to the shim stack and change pistons if desired. See below for our piston tuning guide. After desired vavling is installed, tighten ring nut and torque to 25 ft/lbs.
Mustang Strut 2011/2012 Piston Selections: Piston selection is critical to achieve your desired damping curve. For recommendations, please contact a Penske Racing Shocks representative.
Mustang Strut 2011/2012 Reassemble: Once you have your desired piston and shim stack on the shaft assembly and the ring nut is torque, you are now ready to reassemble the inner tube. 1. Install Floating Piston tool TL TL-FP-MUSTANG (j) into body. Do this by removing the inflation valve, then thread the tool into the floating piston, then into the body. This will hold the floating piston in place so you can properly bleed the shaft assembly and will. (j) Remove with 7/16 socket.
Mustang Strut 2011/2012 (l) (n) (k) (m) Next take the shaft assembly and submerge it into the oil, make sure the cross holes,(k), on the shaft are submerged in the oil, from this point on, don’t allow the cross holes to come out of the oil. Manually displace the shaft up and down (l). You will get air out of it initially; continue to displace the shaft up and down until you get a smooth, solid feel.

Mustang Strut 2011/2012 Warnings: Make sure the circled bolts torque to the appropriate spec before running vehicle. By not having proper torque, strut could become loose and cause damage.
