Product Details

The Skunk2 521-99-1010 Race Spring is a straight-style coil spring measuring 7.0 inches in length with a 2.5-inch inner diameter and a spring rate of 6 kg/mm (335 lb/in). Sold individually, these race springs give experienced tuners the flexibility to build fully custom suspension setups tailored to their specific performance goals.

These are the identical springs found in Skunk2's adjustable coilover kits, and are also available separately for mix-and-match tuning across a wide range of lengths, rates, and profiles — including straight, elliptical, and cone-tapered designs.

Key Features:

  • Dimensions: 7.0" length x 2.50" inner diameter
  • Spring Rate: 6 kg/mm (approximately 335 lb/in)
  • Style: Straight coil spring
  • Construction: CNC-wound from SAE 9254V high-quality spring steel
  • Finish: Shot-peen stress relieved, phosphate treated, and gloss powder coated for corrosion resistance
  • Sold individually (1 spring per order)
  • Direct replacement or upgrade spring for Skunk2 adjustable coilover kits

How to Read a Skunk2 Spring Part Number:

Example: 0700.250.006

  • 0700 — Spring length = 7.0 inches
  • 250 — Inner diameter = 2.50 inches
  • 006 — Spring rate = 6 kg/mm

Spring Rate Conversion: 1 kg/mm = 55.88 lb/in

Skunk2 Race Springs are precision-engineered for sport compact performance applications, offering a durable, track-tested solution for tuners who demand exact control over their suspension setup.

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

Super easy to browse web site and find the product I wanted.<br>The price was unmatched.<br>Shipping was fast and cheap.<br>Super shopping experience.

Great prices, helpful customer service. Ordered 2 by mistake. And they got it cleared up real fast. Saved over $80 off retail. Will be ordering from the, again!!!!! <br>

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.

Excellent service with the actual stock on hand, shipment was made the next day and a tracking number was provided. I have tried 2 other online supply stores which don't know what they have in stock.
