About SDI – Suspension Direct Inc.

Suspension Direct Inc. (SDI) has built its reputation as one of the most respected names in off-road and performance suspension. Suspension kits, shock absorber kits, coil springs, and a full range of chassis components form the backbone of a catalog that serves everyone from weekend trail riders to professional racers. Founded on the principle of being a true one-stop shop for suspension components, SDI has grown into an industry leader in suspension and chassis innovation for Side-by-Side UTVs, motocross bikes, trucks, Jeeps, and beyond.

Racing Roots, Real-World Results

SDI's engineering pedigree runs deep. The brand was built on hands-on experience as suspension engineers and test riders, working alongside some of the most iconic names in motorsport — including Factory KTM, Joe Gibbs Racing (MX), and championship-winning riders like Ricky Carmichael and Chad Reed. That race-bred knowledge translates directly into the components SDI designs and distributes, giving everyday riders and off-road enthusiasts access to genuinely competition-tested technology.

One of SDI's most notable innovations is the E-CLIK Intelligent Active Suspension (IAS) system — a semi-active electronic coilover platform that uses an ECU, IMU, and touchscreen controller to continuously adapt damping to terrain in real time. It represents the cutting edge of what suspension engineering can deliver for UTVs and trucks alike.

A Broad Suspension Catalog

Beyond their own manufactured lines, SDI leverages deep partnerships with the industry's top suspension suppliers — including WP, Showa, KYB, Walker Evans, and Fox — to offer a remarkably comprehensive parts inventory. Whether you need a single shock absorber bushing or a complete suspension kit overhaul, SDI stocks components down to the individual part level, reducing the need for expensive full-assembly replacements.

Their catalog also extends into chassis support components such as motor mounts, which play a critical role in keeping drivetrain forces from upsetting suspension geometry — an often-overlooked factor in overall handling performance. From the spring rates that govern ride height and compliance to the coil springs and shock bushings that maintain precise geometry under load, SDI approaches the suspension system as a whole.

Who SDI Is Built For

SDI products are designed for Polaris, Can-Am, Honda, Yamaha, Kawasaki, and Arctic Cat UTVs, as well as popular truck platforms like the Toyota Tacoma, Ford Raptor, and Jeep. Whether you're building a race machine or simply want a more controlled, comfortable ride on the trail, SDI's combination of engineered product lines and top-brand distribution makes them a go-to resource for serious suspension upgrades.
