Horstman has been a go-to name in karting for chassis and suspension setups that take a beating on the track. They make parts that keep your kart planted through corners and straight on straights. No fluff, just components built for guys who race every weekend.
Horstman Torsion Bars
These bars control suspension flex better than coil springs in most setups. Pick from different diameters and lengths to match your kart's weight and track conditions. A 1-inch bar works for lighter 125cc classes, while 1.25-inch handles heavier outlaw karts. They resist twisting under load, so your axle stays level over bumps. We've tuned plenty of Horstman bars on dirt ovals, and they dial in handling fast.
Axles and Spindles
Horstman axles come in solid and hollow styles, with options for camber adjustment. The 1-inch solid axle suits sprint tracks; go hollow for more give on loamy dirt. Pair them with drop spindles to lower your center of gravity without messing up bump steer. These hold up to 40 hours of hard racing before needing a check.
Chassis Components
Full chassis frames, kingpin kits, and brake components round out the line. Their welded frames use 4130 chromoly tubing for strength without extra weight. A-arms and radius rods keep geometry precise lap after lap. We stock hubs that fit most rear ends, from Winters to Galigher.

Installing Horstman parts means less downtime. Swap a torsion bar in 30 minutes with basic tools. They run cooler than competitors in long mains, cutting fade. Racers tell us these setups shave seconds on technical tracks like tracks with whoops and hairpins.
