Lower suspension insulator / lower load pad About

MACK 10QK36B - LOWER SUSPENSION INSULATOR / LOAD PAD - RUBBER - FOR SS34/SS38/SS44 AND SW/ST34 SERIES SUSPENSIONS - 4 PCS PER TRUCK Part No. - Mack 10QK36B Part type - Lower suspension insulator / lower load pad Vehicle - Heavy-duty / semi-truck Manufacturer / OEM - Mack Position - Rear suspension Suspension type - Mack 4-inch spring / Camelback-type suspension Material - Rubber for the standard version Length - Approx. 6-7 inch depending on catalog measurement / reference version Width - Approx. 6-7 inch Height - 3-3/4 inch (=96 mm) Pin / button diameter - 1-3/4 inch (=44.5 mm) Qty. per vehicle - 4 Main function - Supports / cushions the suspension load and reduces metal-to-metal contact, vibration and shock Cross references - 10QK36C, 10QK388, 21036254, 25125064, R302920, R307480, E-2920, E-7480, MA36000, EM47300, 325110/325123, ABP2P The Mack application data gives the lower pad dimensions as 181.77 mm (7-5/32") length 177.80 mm (7") width 96.04 mm (3-25/32") height. Other catalogs measure the pad/plate itself as 6" x 6" x 3-3/4", so the difference is measurement convention / physical configuration. Where is 10QK36B used? - It is used in Mack rear suspension systems, particularly: Mack SS34 / SS38 tandem suspension Mack SS44 Mack S550 Mack SWS57 Mack ST34 tapered-leaf suspension Mack SW / SWW Camelback/walking-beam suspension The documented applications include Mack 38,000-, 44,000- and 46,000-lb rear suspension configurations. Important distinction - 10QK36B = LOWER suspension load pad / insulator. It works together with an upper insulator / load pad. For example, 10QK365A / 25121508 are listed as upper pads for relevant Mack SS /SW / ST applications.
