AEM Electronics offers this special kit designed to adapt the frame of a 1973-87 Chevy C10 pickup (long or short bed) to accept a 12-21 Model S or 15-21 Model X Tesla rear subframe/motor assembly. Each kit is pre-engineered to rigidly mount the applicable Tesla subframe in the correct position on the truck frame—to achieve proper suspension geometry while substantially increasing the rigidity of the truck frame. The kit also incorporates upper coilover shock mounts to pair with Holley part number HEV001-001; this successfully converts the stock Tesla coilover suspension to an aftermarket coilover shock system that's positioned lower to allow a clean fit into the swap truck without having to clearance any of the truck bed. Depending on the coilover shocks used, this subframe mount kit will accommodate a 4-6 in. drop from factory ride height in the rear of vehicle—so it's advisable to also lower the front of the vehicle. (An excellent addition to this kit is the SpeedMax kits for the front of the vehicle offered by Detroit Speed.)

NOTE: This kit requires notching of the truck frame and installs very similarly to a typical C-notch kit. It is also required to drill additional holes in the frame to rigidly bolt the subframe mounts to the frame. While welding the frame mounts to the truck frame is not required, it is possible to further strengthen the assembly.

Depending on the front-end conditions of the vehicle and the weight balance front to rear, it's recommended to run 200 to 300 lb.-in. coil springs with the coilover shocks (not provided). Coilover shock/spring assemblies should be standard 14 in. x 2.5 in. size.

* Wheel recommendations: The Tesla suspension has a wider track width than the OE truck track width does. In order to fit wheels and tires in the fender wells without modifications, AEM recommends using 10 in. wide wheels with an 8 in. backspace measurement to optimize clearance with the outer fender and the frame rail on the inner side. Wider wheels will not fit without modification. If narrower wheels are chosen, the backspace should be calculated in a fashion that keeps the position of the outer face of the wheel in the same location (width should be removed from the inside of the wheel).
