A true high performance washer from ARP, available in a variety of sizes and thickness, and with or without I.D. (inside diameter) chamfers. All are constructed from premium chrome moly and are parallel-ground, hardened, and finished in black oxide. Our 3/8 I.D. washers, for example, come in four different sizes (O.D.) and different thicknesses. Special connecting rod washers are available, as are some of the more popular metric sizes. All of the washers are available individually, with most of them also
offered in handy 2-piece and 10-piece packages. Build up an inventory of these premium quality washers so you wont get caught short when the need arises.

Found a Thule Vertex bike hitch on here for $50 cheaper than amazon. Extremely fast shipping. Definitely recommend purchasing from here.

Great prices, reasonable shipping costs.  Shipped within 3 days of order.  Didn't receive discount for valid coupon code (25OffShipping).  No response to 2 emails.  No indication of expected delivery date.  Lots of unknowns but you can't beat the pricing.
