Detroit Speed ARP Stainless Steel Body Bolt Kit (1968-1974 GM X-Body) - 010803DS
Finish your classic GM X-Body body mount installation with premium hardware designed for the job using the Detroit Speed 010803DS ARP Stainless Steel Body Bolt Kit. Built around 1968-1974 X-Body applications, this kit replaces critical body-to-subframe and core-support mounting hardware with polished 17-4 stainless steel fasteners. It is an ideal companion to Detroit Speed solid body mounts and provides the proper hardware needed when tightening up the chassis connection on a performance-oriented restoration, street machine, or Pro-Touring build.
The 010803DS kit includes application-specific hardware for the X-Body chassis rather than simply supplying a collection of generic fasteners. Detroit Speed includes two 5/8-11 x 3.5 inch body-mount bolts and two 5/8-11 x 4 inch body-mount bolts, along with two 1/2-13 x 3 inch core-support bolts and two 1/2-13 stainless steel Nylock nuts. The different body bolt lengths accommodate the mounting requirements of the X-Body chassis.
Detroit Speed also includes two factory-style aluminum firewall body mount spacers. These spacers are important because Detroit Speed specifies that 1968-1974 Nova-style X-Body applications require spacers at the firewall body mounts between the body mounts and the body. Including them makes the 010803DS a purpose-built hardware package for this chassis rather than a universal stainless bolt assortment.
The polished 17-4 stainless steel construction provides durable, corrosion-resistant hardware while delivering the clean appearance expected on a detailed chassis build. Detroit Speed specifies 35 feet-pounds of torque for the core-support fasteners and 85 feet-pounds for the frame-to-body fasteners. Anti-seize should be applied to stainless steel bolt threads during installation.
