What ESD does.
Suspension parts manufacturing, custom one-off fabrication and installation services — all at our Ontario, CA facility.
Manufacturing services
Every component we sell is built here. These are the things we manufacture.
Airbags and brackets, four-link systems, step notches, C-notches, control arms, mounting hardware and fabrication components. All designed and built in-house. If it's in the ESD catalog, we made it at our Ontario, CA facility.

Installation services
Available for customers who can bring their vehicle to our Ontario, CA shop.
Complete front and rear air ride installs using ESD-manufactured bags and brackets. Air management system setup, line routing, and leak testing included. We install what we build, so we know exactly how it goes in.
Full kit installs for lowering and lifting applications — drop spindles, flip kits, lowering shocks, lift kits and extended control arms. Alignment check included. ESD parts or your preferred brand.
Step notches and C-notches cut, welded and reinforced at our shop to allow maximum drop clearance without axle contact. Measured, cut clean and finished — not hacked in.
