Datsun 510 to S chassis adapter hub installation guide
INSTALLATION GUIDE
Foreword
JBC provides suspension components to facilitate the conversion of the front suspension to use Nissan S chassis suspension and brakes into the Datsun PL510. The components are designed with complimentary suspension points to produce favorable suspension geometry in a lowered car. The kit is not complete and will require additional parts to be purchased.Given the vast amount of aftermarket parts available for these cars JBC does not guarantee our components will work effortlessly with all possible suspension combinations.

In this guide we will go over the installation of all of the JBC front hub components
Please read through the entire installation guide before getting started on your project.
Preparation
Before getting started, gather all of the parts needed for the install.
JBC front hub kit. (Comes with hubs only at this time)
Third party parts that need to be sourced elsewhere:
A set of wheel bearing assemblies from a B16 Sentra, 2007-2012.
MUST BE FRONT HUBS NOT REAR.
There are several options available so make sure you get the right parts for your desired build. All variants should be compatible.
The most common is the basic 4 lug 4x114.3 hub available from the 2.0L engine Sentras. These come with and without ABS , most people will want without.
There are also 5 lug 5x114.3 hubs available for anyone completing a conversion. These are available from the 2.5L engine Sentras. These come with and without ABS.
Brake components
The caliper mounting locations and brake rotor offset mimics the exact positioning of the stock Nissan S chassis components. This means that a very simple low cost upgrade is to simply use oem S13 or S14 calipers and rotors and bolt them in place.
Alternatively, any bolt-on brake kit made for the S chassis should also bolt-on to this kit.
There are many options for sourcing these parts so we won’t list any here but stock 240sx parts from any parts store are the baseline option.
Steering Arms
OEM or JBC arms will work equally well with use of OEM ball joints
Coil overs
The strut mounting locations on the JBC hubs are designed to match the S chassis bolt pattern with angles appropriate for a lowered 510.
Any OEM or coilover suspension for an S chassis should bolt-on. This means that you get the option of shopping the entire S chassis coilover aftermarket, either budget friendly or maximum bling factor.
Wheels
The hubs locate the ball joint about 1 inch further backwards on the hub for added caster in the suspension geometry. This moves the steering arm backwards relative to the center of the wheel which means that a larger than normal wheel will be needed to clear the outer tie rods.
15” wheels may not fit but will at least be very tight.
All 16”and up wheels should fit fine.
Hardware
Hub threaded inserts:
The steering arms bolts are threaded into the aluminum hubs. For better wear resistance and strength, a steel threaded insert is used. These inserts convert the aluminum M16x2 thread to the correct M12x1.75 thread of the steering arm bolt.
QTY 4 are needed and can be bought here: https://www.mcmaster.com/97084A260/
An installation tool is also offered but an appropriate sized flat head screw driver also works fine.
Steering Arm bolts:
The steering arms (OEM or JBC) are then held on by high strength M12x1.75, 30mm length bolts, hex head recommended for clearance.
QTY 4 are needed and can be bought here: https://www.mcmaster.com/90854A226/
Hub bolts:
The wheel bearings are held to the aluminum hubs by M12x1.25, 50mm length socket head cap screws
QTY 8 are needed and can be bought here:https://www.mcmaster.com/96144A303/
Brake caliper bolts:
The wheel bearings are held to the aluminum hubs by M12x1.25, 50mm length socket head cap screws

M12 Washers:
Various washers for the M12 hardware.
