This document is the manufacturer's installation instruction sheet for Lakewood Traction Bars, part #21715, published by Lakewood Industries (a Mr. Gasket Performance Group Company), copyright 2001. The kit fits 1986-2000 Ford F-150 pickup trucks and 1973-1987 Chevy/GMC 1/2-ton 2-wheel-drive pickup trucks. The sheet opens with safety warnings about working under a supported vehicle (never use a bumper jack), then details preparation steps: leveling the vehicle, blocking the front wheels, and supporting the rear axle on jack stands without letting the axle hang. The nine-step installation procedure covers attaching the snubber with the supplied Ny-lok nut, positioning the traction bar with the rear mount bracket behind the axle and the snubber under the front spring eye, clamping the bar to the leaf spring, setting a recommended 1/8" snubber-to-spring-eye clearance gap using included shims, and torquing the front and rear clamps to 45-50 lb-ft. Final adjustment guidance recommends zero gap for competition vehicles and a 1/2" right-side / 3/8" left-side gap for street/strip use. Notes warn that the snubber end must angle up or be parallel to the chassis and that the snubbers must not be used to level the vehicle. A "Recommended Adjustments" section begins at the bottom and appears to continue on another page.
