B8 5100 rear shocks

Chosen

Bilstein

Received

Bolted in at the top by 14 Oct 2026, not yet connected at the axle

Part number: 33-318950

Why this option

Matched to the 6112 front kit so damping is consistent front to rear rather than mixing valving philosophies across the truck.

Trade-offs

Fixed-valve monotube — no adjustability if the loaded and unloaded ride ends up wanting different damping.

What it actually cost

Part: $228.48
Tax: $22.49
Hardware not included: $30.88
All-in: $281.85

$255.90 for the pair on eBay on 2 Sep 2026, less a $12.80 item discount and a $14.62 share of that order's $37.27 coupon (split by line value across the items kept; tax was charged before the coupon). Hardware is from the Stumpf Ford axle-parts order as shipped: two lower mounting bolts W506545-S439 and two nuts W520214-S440, which the workshop manual says to discard, plus two shock retainer nuts W720200-S440.
