Strange STS7209S Ultra Series Drag Race Coil-Over Shocks Double Adjustable 8.25" Stroke Piggyback Reservoir (each)

Strange Engineering brings advanced shock technology into the Drag Racing market. As racers become more knowledgeable in chassis tuning, many are seeking qualities normally reserved for tier one vehicles used in other forms of motorsports. These double adjustable shocks address the internal events that normally occur during use, drastically reducing undesired changes in shock dampening. Monotube construction is lighter (and less unsprung weight) than a twin tube design, and dissipates heat more efficiently. The shock features a hollow shock rod, which has less inertia making it more responsive to changes in direction; In addition, the shaft is optimally hardened for increased strength, chromed, and super finished to provide superior life and reduce both deflection and friction. The ultra low friction guide and seal are self aligning that reduces low speed abrasion and wear that occurs during side loading and temperature changes. The large 48mm piston is manufactured from billet aluminium, hard anodized, and Teflon coated. The larger piston area achieves higher dampening forces with lower internal pressures. A thin Teflon coated piston band further reduces friction while allowing a straighter port design that minimizes changes in fluid direction. The result is faster frequency response and lowered hysteresis, which permits a more progressive dampening force without the downside of additional lag that would normally accompany it. The extension and compression oil paths are completely sealed from each other eliminating any cross talk between them.

Features:

MONOTUBE CONSTRUCTION

• Lighter weight / High heat dissipation
• Can be operated inverted- Reduces unsprung weight and provides consistent chassis reaction

GAS CHARGED INTEGRAL RESERVOIR

• Floating piston compensates for oil displaced by piston rod as shock is compressed

WIDE RANGE OF TUNING ADJUSTMENT

• 24 clicks for both compression & rebound
• Clicks are Independent and positively lock
• Allows for fine tuning for varying conditions
• Adjustments are made with a standard 5/32" Allen wrench

ULTRA LOW FRICTION GUIDE AND SEAL

• Reduces wear during side loading and temperature variations, which maximizes performance consistency

HOLLOW INDUCTION HARDENED SUPER FINISHED CHROME ROD

• Lowers inertia, while minimizing deflection and friction

48MM HARDENED PISTON WITH TEFLON COATING

• Provides precise low speed control while maintaining consistency
• Large working pressure area allows for higher dampening forces
• Straighter port design improves oil flow for a quicker response time
• Hysteresis is minimized resulting in improved grip and stability
• Improved stability and traction at launch and down track

PISTON BASED VALVING SYSTEM

• Isolates compression and extension adjustments from affecting each other
• Decreases blow off force requirements / Improves frequency response
• Superior low speed control
• Allows for improved launch control and reduced tire shake

LOCKING ANODIZED SPRING SEAT

• Spring seat and body threads have dissimilar coating for corrosion & galling resistance

INTEGRAL (PIGGYBACK) RESERVOIR

• Can be converted to air adjustable
• Compression adjustment is located in-line with oil flow (working pressure column) reducing oil shear, hysteresis and improving small amplitude frequency response- compared to designs that are adjustable at the canister
• Allows for easier spring installation over a wide range of shock lengths
• Enables use of a longer and lighter spring for improved stored energy
