The (UL) Ultra-Lite Road/Track Coilovers are the ultimate in all-around performance and handling. It also features the aluminum pillow ball upper mounts and independent ride height and spring preload adjustability. For the serious Motorsports competitor, the UL version shares all the same features of the Race version but incorporates aluminum strut housings for an approximate 10% decrease in weight making them the competitor’s choice for those watching un-sprung weight. We have used these coilovers for dual duty, Drag and Autocross setups with great Success. With all the adjustment and spring options, it is possible to set up the vehicle to meet all situations and scenarios. Thought the strut housing is aluminum to save weight, the POWERTRIX (UL) Ultra-Lite coilovers use heat tempers forged steel for bottom mounting cups (where other companies use aluminum) for maximum strength where is it needed the most at the point of where the coilover assembly bolts to the hub of the car.
The (UL) Ultra Lite Road/Track Coilovers aluminum shock bodies make an entire assembly approximately 2-3 lbs. lighter than the standard (RT) Road/Track version coilover assembly. Though this does not sound like a lot, it can make a big difference performance-wise when the dynamics of sprung vs. un-sprung weight is considered.
Sprung weight is defined as a parts weight while in motion or constant oscillation. Un-sprung weight is the actual weight of the part as it is at rest or not in motion. Sprung weight is calculated to be approximately 3-4 time its un-sprung weight.
Therefore a coilover assemble that is 2-3 time lighter than another can be as much as 6-12 lbs. lighter while in motion, so calculating that savings on each corner of the car can be as much as 24-48 lbs. of weight savings.
» Re-buildable/Replaceable Premium mono-tube aluminum strut Body
» Pillow ball upper mounts
» Race Grade 55mm aluminum shock body
» 15 way strut damper adjustments
» Independent Ride height and Spring Preload adjustability 13kg/mm front and 11kg/mm rear
All coilover kits are rebuild-able so it will be the last strut and spring combination you will ever need. Fine tuning of the suspension is also possible for any and every type of driving style, or motorsports events as custom spring rates are available from 3kg/mm (168 lbs/in) – 17kg/mm (952 lbs/in)
Note: + or – 2k on spring rate changes will require re-valving.
NEWEST UPGRADES & OPTIONS:

3.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 harsh outside elements.
UPGRADE to The SWIFT Springs advantage:POWERTRIX has partnered with SWIFT Springs to offer the very best in suspension spring technology. 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. Highest durability against loss of spring height = excellent material memory prevents springs sag.
4. Extremely light weight to reduce sprung weight increasing over all agility.
