Bilstein 5125

Bilstein 5125's are a monotube, nitrogen charged design.  The monotube design means a bigger working piston and a larger working tube area which means better cooling and better performance.  The 5125's are charged at a much higher pressure than twin tube shocks which better prevent aeration.  Additionally, these shocks are really where we can start applying shock valving that is really meant for our fullsize Chevy trucks rather than a more generic shock. 



$380 for a set of four (or $95 each).  For Chevy trucks with 4" of lift or less it's highly recommended to switch to longer front shock mounts to make sure that they don't bottom out.  The Bilsteins have a longer body due to their design and so they need more space between the shock mounts than twin tube shocks.

Guys always ask us if the Bilsteins are worth it, nobody ever regrets buying a good shock. At this level of shock, you pretty much get what you pay for.

The shocks on this page apply to the '67-'87 ('91) Chevy 4WD trucks, including Blazers and Suburbans.  In 1988 GM switched their truck line up to independent front suspensions with a body style change, however, the full size Blazers, Suburbans and crew cab and cab & chassis 1 ton trucks stayed the old body style (with a solid axle in front) through 1991.

The lengths given are for the stock shock mounts, the Bilstein shocks use 1/2" bolts through each eye (the sleeve in the shock is removed for the frame side of the rear shocks).

Shocks for '76-87 (Up to '91 For Crew Cab and Cab & Chassis) 1 Ton Chevy Trucks

1 ton rear axles use 9/16" bolts through the shocks on the axle side, these are unique to the 1 tons and not supported by the aftermarket.  You can:

  •  Weld a 1/2" washer on each side of your shock brackets

  • Drill the bracket out to 5/8" and delete the sleeve in the shock, use a 5/8" bolt

  • Replace the shock mounts with our shock tabs.  If you choose to replace the shock mounts, use the shock lengths for a 1/2 or 3/4 ton truck so that the shocks don't hang too far below the axle.

  • When using a shackle flip on a 1 ton rear axle, it's common for the shock tabs to need to be relocated higher up on the axle tube as the shock body can contact the axle tube.  It's also a good time to consider our shock tabs as they use the more common 1/2" bolt size

ORD-F3 Shocks are a special 5100 series Bilstein that we've selected because the valving works excellent on full size Chevy trucks.  We use them on the front wherever they fit, we modify them in house to fit '73-'87 ('91) Chevy trucks.
