SF Racing is the largest shock part supplier and authorized service center in the midwest for PEP.


SF Racing handles all your shock needs from new ATV shocks and ATV suspension to services second to none.


SF Racing has your ATV suspension services covered.


SF Racing is the official Midwest distributor of PEP Suspension and other PEP products. We are the only PEP certified service and repair department in the Midwest. Don't send your parts to a company that does not know your shocks. Send your suspension to our trusted experts to be properly serviced and repaired in house.


SF Racing was started in a small southern Illinois shop.  Thanks to all of our loyal customers, we have now moved to northern Illinois and have grown into the successful business that it is today.  We have expanded our work space to accomadate our world-wide customer base.


SF Racing is owned and operated by Seth Fligge.  This is Seth's 28th year of racing quads and his 17th year of servicing, building, and tuning ATV suspension.  We travel around to as many quad events that our schedules allow us to.  If you can't find Seth on the track then you will find him in someone's trailor or on his knees bouncing bumbers and checking ride heights. I mainly travel the atvmx series races Walnut, Red Bud, Unadilla and Iron Man.


I also two four-legged sons.(Oliver is our 5 year old European Great Dane and Stanley is our 7 year old Golden Retriever.) Stanley and Oliver love to travel around with us from track to track.
