Powertrix (RT)Road/Track Coilovers – 240SX S13


SKU: RT-S13 Category: Tags: , , , , , , , , ,


The (R/T) Road/Track Coilovers feature the same robust premium grade mono tube dampers/shocks as our (SS) Sport Street Coilovers system, but adds the increased performance dimension of pillow ball upper mounts. Which transfer more suspension energy through the strut piston shaft increasing the efficiency of the overall suspension duty. Full forged steel threaded shock bodies for independent ride height and spring pre-load adjust-ability and 8k/6k linear springs make the (R/T) Coilover System an “All Business” tool for Auto crossing and Road Racing with the ability to go to and from the track on. Designed for the true performance enthusiast looking for the extra edge during track time yet offers a ride quality comfortable enough to run on the street on a daily basis.


  • Direct Bolt On Fit, no modification required.
  • Independent Ride height and Spring Preload adjust-ability
  • Rebuild-able/Replaceable Premium mono-tube forge steel strut Body (inverted front)
  • Front Adjustable Camber Plates and Rear Pillow ball upper mounts
  • 15 way strut damper adjustments

Anti-Corrosive Magnicoated Damper Housings (PPI) Polymer Plastic Injected dust boots (New Feature)Upgraded Front Lower mounting bracket and bushings (New Feature)

(Standard 8k/6k Spring Rates) 175mm front and 200mm rear spring length.*Custom Spring Rates also Available

*All coilover kits are rebuild-able / replace-able so it can be last strut and spring combination ever needed. Fine tuning of the suspension is also possible for every type of driving style. Custom spring rates are available from 3kg/mm (168 lbs/in) – 17kg/mm (952 lbs/in) Note: + or – 2 kg/mm on spring rate changes will require re-valving.



Longer mounting cup to provide more mount to shock thread contact for increased structure ability.

Upgraded Bushing durometer for increased suspension performance and durability yet still maintaining comfort.

NEW for 2016 (BLACK) Magnicoated Damper Housings

Dampers / Shocks will now be (BLACK) Magnicoated. Magnicoating is a high performance corrosion protection coating.

It is a chrome-free duplex coating engineered specifically for automotive use and other structural components. This process is much stronger than conventional e-coat (zinc style plating), and will provide extended field protection, and minimizes the degradation of the structure – ability of the material.

NEW (PPI) Dust Boots

(PPI) Polymer Plastic Injected dust boots – These plastic injected boots are proven to be more durable and will resist breakdown due to the outside elements. 


For best results, we recommend upgrading to the Swift Springs.

SWIFT spring composition is manufactured using their own proprietary steel alloy “HS5.TW”. This material was formulated in order to maintain the 4 major performance factors listed below, as well as achieving the fastest reaction speed possible to get compliance on road surface conditions.

“SWIFT springs are created with proprietary winding methods, as well as some other trade secrets focused on ensuring the their product separates them from the standard market.”

 The 4 Factors that separate Swift from the rest of the spring industry: 

  1. Consistent spring rate throughout the stroke = more consistent performance
  2. The largest amount of stroke to maximize suspension motion.
  3. The highest durability against loss of spring height = excellent material memory prevents springs sag over.
  4. Extremely light weight to reduce sprung weight increasing over all agility.
