Bilstein B16 (PSS10) Coilover Kit
Utilizing Bilstein''s monotube shock absorber design for heat dissipation and ride control, the PSS10 (B16) Coil-Over System, evolved from the PSS9 system, adds a matched performance spring and threaded ride height adjuster to provide a complete suspension system for your vehicle.
The Bilstein PSS10 (B16) Coil-Over System offers ten vehicle adjustment settings and includes numbered adjusters at the base of the shock body so you know exactly what setting you are on without counting clicks. Set your vehicle low and tight for optimized performance or revert to a more stock-like ride height and handling characteristics.
This system features both coil-over and standard monotube gas pressure shocks with performance level valving along with application specific, progressive rate coil springs. Ride height adjustments can be made on the vehicle without removing the suspension. The solid aluminum spring seat and lock nut allow a selective adjustment of the vehicle''s ride height. Spring travel and vehicle body height change, but the spring seat remains pre-loaded throughout the allowable range of adjustment.
- Ride height adjustable from -1.0" to -1.75" (front) & -1.0" to -1.75" (rear. minimum 1" lowering)
- Wrenches to adjust front and rear ride height included!
- Lighter weight reduces wear and tear on suspension components
- About the Bilstein Shocks Included in this System
All Bilstein gas pressure struts/inserts and gas pressure shock absorbers operate on the same principle. They are manufactured with the rod pointing down into the strut tube, thereby utilizing the thicker, stouter body portion of the shock absorber to dissipate side loads. Consequently, due to the increased diameter and surface of the pressure tube, the Bilstein gas pressure strut/insert or shock is better suited to take increased side loads when compared with the conventional version.
Additional advantages, based on development strongly influenced by the motorsport industry, include greater stability, better road handling, and accurate steering. And extremely high quality manufacturing and materials as well as a weather resistant coating to resist oxidation, mean Bilsteins will last approximately four times as long as Original Equipment.
Battling Heat Build Up
Conventional shocks trap the heat within the shock body and prevent adequate dissipation, making them prone to heat build up, fade and eventual failure.
Bilstein's patented design allows the excessive heat from the oil to transfer to the outer surface of the shock body and dissipate more efficiently. The dividing piston also permits the oil to expand as heat builds, preventing aeration (foaming) and viscosity loss. This allows the shock to maintain full damping characteristics as temperatures rise.
The tube of a Bilstein gas pressure shock or strut is fabricated using a special extrusion method. This process achieves an extremely tight peak-to-valley tolerance and maintains consistent wall thickness. Bilstein's seamless monotube design provides superior tube strength while maximizing heat dissipation and shock life.
Ride Comfort and Performance Without Compromise
The piston head design allows independent tuning of the compression and rebound damping forces to provide optimum ride comfort and performance without compromise. It features fewer parts than most conventional designs. The product's simple, yet exceptionally functional digressive design contributes to the extreme durability and long life of Bilstein Shock Absorbers.
Better Built
Bilstein's shock bodies are precision formed through a unique seamless extrusion process. This provides superior strength along with high finish tolerances. The shock body is then treated with a special paint finish durable enough to withstand grueling 240-hour salt spray tests. The finished body is mated with a solid, induction-hardened steel chrome plated and polished shaft, machined valving components and highest quality seals.

Save yourself the headache and go with something else. Bought these based on the Bilstein name. Installation is a pain compared to other coilover systems. Can't adjust the spring compression without changing the height. Doesn't come with top hats and you have to bore your OE top hats to fit, so if you ever decide to switch to something else, you're scrapping the top hats too. You have to disassemble and reassemble the entire rear adjustment system based on lackluster instructions in broken English in order to complete the installation. You have to carve up your interior trunk liners to get access to the adjusters, and the only way they properly reach through is if you have a near maximum height drop/maximum spring compression on them.
All of that just for my rear adjusters to end up stripping after 6 months of use so they just free spin and have no effect on the damping anymore, and you can't replace anything on these without buying a whole new set of coilovers. Oh, and the warranty is worthless, which is surprising for Bilstein.
This was my upgrade to the factory bilstein struts with swift spec r springs. Over all these are amazing coilovers and do an excellent job supporting the car in the off road rally X of New Mexico and Colorado. Only down side was you have to get a drill bit and expand the rear strut mount hole. After that the sturts bolt up super easy and we were able to dial in the alignment easily.
