Product Details

The Vortex CK5231 is a complete 520 chain and sprocket conversion kit featuring a hardcoat aluminum rear sprocket and a high-performance SV3 series drive chain. This kit is engineered for riders looking to improve acceleration with a shorter gear ratio, dropping one tooth in front while retaining the stock rear sprocket count.

The included 520SV3 chain is manufactured in Japan to premium quality specifications and features a dual pocket sealing system that delivers up to 7 times longer wear life compared to standard O-ring chains. The pre-sized 114-link chain requires no cutting or modification — this kit is truly ready to install straight out of the box.

Kit Specifications:

  • Chain: 520SV3 — 114 links, Japan-made, dual pocket sealed
  • Front Sprocket: 15 teeth (steel)
  • Rear Sprocket: 43 teeth — hardcoat anodized aluminum
  • OE Gearing: 16/43
  • Kit Gearing: 15/43 (one tooth down in front for quicker acceleration)
  • No chain cutting required — pre-sized for direct installation

Key Features:

  • SV3 dual pocket seal technology for extended chain life
  • Hardcoat aluminum rear sprocket for reduced rotating mass
  • 520 pitch conversion reduces weight over larger OEM chain pitches
  • Complete kit includes front sprocket, rear sprocket, and chain

This Vortex chain and sprocket kit is an ideal upgrade for riders seeking sharper throttle response and quicker acceleration from a drop in overall gear ratio. Compare OE gearing to kit gearing to fully understand the ratio difference before installation.

The experience was very good and fast. Thank You

easy to find the Cab Spoiler for my 2003 GMC Sonoma Extended Cab SLS. Great price also!

GOOD SO FAR

Quick and easy. Good price

Great experience

Ok

Saved some money and it was quick and easy to checkout

Very easy to order , not to shabby.

Great price and easy ordering. Had a problem with the sensor not turning on the fans. Used an old sensor and everything is working good now.

Easy lookup and like style of shock listing

If this item is real at this price, this is the best shopping experience of my life so far.

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.
