This listing is if you want us to re-valve YOUR OWN Bilstein Miata front and rear shocks, proven set-up, designed specifically to maximize tire contact patch time on the tarmac; more time = more grip = lower lap times!

We spend time to force-match (pressure balance) your set; every set we’ve worked on has at least one damper that needs multiple adjustments to get it correct, hence more labor. If we charged less you’d either get a mismatch or we’d be out of business!

Return shipping fees included in this listing. Price is EACH, so you need quantity (4) for your car, two front, two rear shocks revalved. If you’re sending springs that will increase shipping fees, we will call you when we’re shipping for the additional carriage fees.

When tested on a dynamometer forces for bump and rebound will not exceed force limits stated in SCCA or NASA rules. Call for details: 888-407-5122.

YOU MUST INCLUDE CONTACT INFORMATION WITH YOUR SHIPMENT! We need your phone (mobile preferred) and email address!


Optional rod guide replacement is $25 additional; the rod guide is comprised of a Teflon-lined DU bushing, new rod seal and outer rod guide o-ring. High-mileage shocks need this part.
