Who Is Super Shox? Meet Brian, the Brains Behind the Perfect Shock Setup
Last updated: November 10, 2026
Brian Goscinski started at Scott Manufacturing in 1987 and started Super Shox in 1997, when he took over the Grayslake machine shop. He is a precision machinist, shock builder, and Harley rider who, in his own words, "always wanted to keep motorcycles out of business because that is what I did for fun." A harsh bagger ride in 2014 changed his mind. By Daytona Bike Week 2015, Super Shox had Harley bagger shocks, and he still checks every setup himself before the build.

The Tinkerer in Grayslake: Machinist First, Shock Builder Always
Brian Goscinski didn't come to shocks from a marketing department. He came from the machine shop. "I started at Scott Mfg in 87 then started Super Shox in 97 when the owner of Scott Mfg was ready to retire and I took over." He studied machining at the College of Lake County, and he still runs Scott Manufacturing, a precision CNC shop, out of the same Grayslake building as Super Shox. On his own résumé he lists the unglamorous skills that make a great shock: multi-axis CNC programming, tool grinding, process engineering, quality control, "design and engineering of shock absorbers," and "setting up shock absorbers for race cars and motorcycles with correct spring rates and damping rates."
Walk into the shop and it feels more like a lab than a warehouse: bar stock waiting to become shock bodies, CNC machines, a test station with damping curves on the monitor, and race car photos on the wall. Brian says the shop also built precision-machined race car parts for Indy Car teams in the 1990s, along with other specialized components. That last line of his résumé is the whole philosophy. A shock isn't just a part. It's a spring rate and a damping curve matched to a load. Get it wrong and the best-machined aluminum in the world still rides badly.

Racers learned that Brian answers the phone. In 2012 the ASCS Lone Star sprint car points leader said of Super Shox, "if you have a question [Brian] is only a phone call away," and described a manual and a dyno sheet for every shock "so you know exactly where you are at." That same year Brian sat on the "State-of-the-Art Sprint Car Shock Technology" panel at Knoxville Raceway, the self-described Sprint Car Capital of the World, alongside guests from AFCO, CSI, Penske and Pro Shocks. Harley riders got the same treatment later. When a rider emailed with detailed valving questions in 2015, the reply came from Brian himself.


Every shock is tested and tuned before it ships.
"Being a precision machinist, my approach has always been accuracy and precise fitments," Brian says. When the shop assembles a shock, the shims are measured and the oil is metered by a filling machine. "The shocks are serial numbered and dyno tested to match the targets we have developed. If the shock does not match it comes apart and gets corrected until it does match the valving profile. There is not a close enough for us it is either right or not." Springs are checked on a compressor at every quarter inch up to coil bind, so the shop can track each batch. Getting a setup right, he says, takes hours of riding on as many different road conditions as possible, at varying loads and speeds.
Born on the Bullrings: Super Shox's Racing Years (1997–2014)
Super Shox started in 1997 with one idea: build a better aluminum monotube gas shock for sprint cars and midgets. Sprint cars are brutal on shocks. They're light, they make huge horsepower, and they run on dirt that changes from tacky to slick in a single night. A shock has to keep the car stable and still let the chassis squat and find grip. Brian wrote about exactly that balance in 2011: running very low gas pressure so the car can "squat and load the tires to get that grip in the slick," without letting the shock cavitate. "It takes a careful balance between valving and gas pressure," he wrote.


Timeline: from a shock idea to the Chili Bowl
(From Super Shox's published history. The wins belong to the racers who ran Super Shox.)
- 1997
The idea for an aluminum monotube gas shock for sprint cars and midgets is born.
- 1998
The first 100% Super Shox runs on a pavement midget at Grundy County Speedway. Sammy Swindell tests a set and wins two World of Outlaws races at Calistoga, California, in his first two nights on them, then makes the switch permanent.
- 2000
First single-adjustable Super Shox built and track-tested.
- 2004
First Super Shox double-adjustable shock launched.
- 2010
The "D9 piston" is developed and, per Super Shox, "significantly improves the performance of the shock."
- 2010–2011
Kevin Swindell wins back-to-back Chili Bowl Midget Nationals on Super Shox, which Super Shox's history calls the first back-to-back win in the event's 25 years.
- 2011
Dirt Late Model debut.
- 2014
Design validation of a Harley-Davidson Super Shox is underway.
- 2015
The SR1 rear shock for Harley-Davidson touring models launches.



Super Shox says racers on its shocks have been "in the winner's circle 1,000's of times, leading to over 75 major championships." Brian puts it this way: "With Super Shox racers have won about every major sprint car and midget race in the US multiple times and numerous titles in Australia and New Zealand over the years."
The Ride That Got Brian Building Harley Shocks
Brian did not set out to put Super Shox on Harleys. "I always wanted to keep motorcycles out of business because that is what I did for fun." As friends started asking for bagger shocks, he tested the idea. "In 97 I got a new Road King and did not really like the suspension and asked a few dealers if there was interest from riders in a better shock, but the feedback was not really and with being so focused on racing it was not a good time to work on motorcycle shocks."
"In 2004 I built a set of shocks for a V-Rod and those worked great." He had moved on from the Road King by 2003 and was riding a Buell and a custom V-8 chopper with a 383 ci 500 hp engine and a rigid suspension. He had not been on a bagger in 10 years. "When I did get on one in 2014 it was harsher than the rigid V-8 chopper. That’s when I figured it was time to get to work on the bagger shocks."
"By Daytona Bike Week 2015 we had bagger shocks and since then the demand has taken over our business and bike shocks is most of what we do." Super Shox launched the SR1 for Harley touring models on June 1, 2015, "engineered for a smooth ride, eating small bumps while lessening the impact of the big hits the rider and their passenger encounter." Every major part was made in-house in Grayslake, every shock was dyno tested, and it came with a 30-day money-back guarantee and a limited lifetime warranty. American Iron Garage called it "the company's spearheading effort into the motorcycle market." American Bagger wrote that year that Super Shox was "loaded with Harley enthusiasts who knew they could take their suspension expertise and apply it to the rough ride of their Baggers." As Brian puts it, "We still stay involved with racing and enjoy helping the racers who use Super Shox win races and championships."

Brian rides. He's on camera riding and testing Super Shox in the company's own videos. You can watch him ride a Harley Ultra on the street outside the shop in "Don't try this unless you have Super Shox!" The shocks get tested by the man who builds them, on the kind of bike you ride.
Looking back, Brian does not point to one trophy. "I have been fortunate to celebrate many wins with racers and work with the best in the business. Hearing from riders who love the shocks and how it has changed how they ride is just as rewarding." He has also heard from riders who say the difference was being able to go hundreds of miles in a day.
"For me this is living a dream, building parts for race cars and motorcycles while owning my own business. There is nothing else that could have brought this level of satisfaction for me it’s not just a job it is my way of life."
What Racing Taught Brian About Your Harley's Ride
Same DNA, different job.
Super Shox motorcycle shocks are gas-assist monotube shocks "built using similar internal parts as our high performance line of racing shocks."
Light on the small stuff, firm on the big hits.
Super Shox describes the motorcycle shocks as having "a very light initial movement to let the suspension move freely, along with advanced valving to control the more substantial impacts." A rider who talked shop with Brian in 2015 described the valving as "light on low speed compression with a stack that steps up control when the shaft speed increases," and said they did "quite a bit of work on the bump stop."
Match the shock to the load.
In racing that meant a manual and a dyno sheet for every set. On a Harley it means the shock is set up for your rider weight, passenger, luggage, and Tour Pak, with a numbered preload scale so you can fine-tune it.
Make it in-house so you control it.
"By manufacturing all of our parts in house we are able to have complete control over the design and machining process," Brian wrote in 2011. In November 2026 he said the shop makes everything in house "other than seals, bearings and springs."
Two Sets of Eyes on Every Setup
Most shocks get picked off a chart and shipped. Every Super Shox set ordered from Dreaded Iron is checked twice before a single part is assembled:
- 1Dreaded Iron checks your setup first. We review your bike, year, rider weight, passenger, luggage and Tour Pak, and make sure everything adds up before we hand it to Brian.
- 2Brian checks it again himself. Brian Goscinski personally reviews every setup before the build. That's the same person who has been matching spring rates and damping to race cars since the late '90s.
We're about 20 minutes from Brian's Grayslake shop and work closely with him, so when a setup question comes up we can talk it through with the builder directly.
