Steering for your E-body
Our 14:1 power steering box conversion kits bolt in with factory-style parts and don’t require cutting your steering column. Challengers and ’Cudas through 1972 use the small-sector kit; 1973–74 cars use the large-sector kit.
Good to know: the updated steering box runs at higher pressure, so we recommend adding a power steering cooler (see “Finish the job” below). Not sure which kit is right for your car? Call or text Peter.
Steering box kits
The Master Kit includes everything for a full swap: steering box, coupler, Saginaw-style pump, bracket, pulleys, hoses and belt.

Building with a Gen III Hemi? There’s a steering kit made for it.
Suspension for your E-body
Not sure where to start? Begin with the lower control arm triangle: strut rods, Delrin bushings and boxing plates tighten the front end and improve alignment geometry. Then add upper control arms, torsion bars, shocks and sway bars as your build calls for.
Start here: lower control arm upgrades

Chassis stiffening for your E-body
Frame connectors and torque boxes stiffen the unibody so the chassis flexes less under power and in corners. Pick your level, then your car: Challenger and ’Cuda use different frame connectors because the wheelbases differ.
- Level 1Frame connectors plus a set of four Hot Rod torque boxes.
- Level 2Adds front inner fender braces and a front lower core support brace.
- Level 3Adds a rear spring relocation kit and a mini-tub kit for up to 4 in. more tire clearance per side.
Early-built 1970 cars: please call before ordering. We have had reports of fitment issues in the torque-box area on early-built 1970 cars.
Dodge Challenger: Level 1, 2 and 3
Plymouth Barracuda & ’Cuda: Level 1, 2 and 3
Brakes for your E-body
Our Mopar brake system upgrade kit is a bolt-in set with Carbon Kevlar pads and shoes, three PTFE-lined stainless-braided brake hoses and DOT 4 fluid. Tell us your vehicle, axle type and brake configuration at checkout, and a technician will be in touch if needed to make sure the right parts ship.
