Mustang II kit Stages 

Fat Man Fabrication offers Stages 2, 3, 4, and 5 to any hub-to-hub suspension kit we manufacture.  All Stages use the same basic parts including our TIG welded tubular steel control arms. The differences are the type of spring used and upper mounts specific to that spring and upper control arm.


Although not shown in photos below all hub-to-hub suspensions include 4 1/2” or 4 3/4” bolt circle OEM style 11″ disc brake kits with your choice of stock height or 2″ drop spindles as standard.

All hub-to-hub suspensions also include paintable TIG-welded mild steel tubular control arms and a manual rack and pinion as standard.


Stage 2 Traditional Coil Spring and Shock

Our huge volume allows us to supply our TIG Welded Tubular Steel Control Arms as standard which eliminates the strut rod by straddling the crossmember for stability. Easily converted to Stage 4 air ride with bolt-on parts and a weld-on shock bracket! Shim alignment is now standard!


Stage 3 Coilover

Stage 3 adds single adjustable coilovers to the TIG welded tubular steel control arms. A shim system is used for ease of adjustment. Easily upgraded to Stage 5 Ridetech Shockwaves with bolt-on parts! 

Now redesigned with a 1-piece upper camber plate and shock mount- easier installation with less measuring and fitting!


Stage 4 Air-Ride

Stage 4 uses Firestone air springs that are so strongly built to act as their own bump stop! The OEM style shock is mounted to the rear of the suspension. Compressor systems and rear air suspensions are available and vary according to your application and budget. We use Ridetech exclusively and can be converted to Stage 2 coil spring with no fab work!


Stage 5 Shockwave

Upgrades the Stage 3 style to Ridetech HQ series Shockwaves. Offers easier adjustability and a premium tunable shock for the ultimate street rod suspension.  - updated upper mounts just like stage 3

All Stages use the same basic parts, including our TIG welded tubular steel control arms and a manual rack and pinion. The differences are the type of spring used and different upper mounts specific to that spring and upper control arm. All Our kits are fully welded and using SAE 1018 steel and we use CAD design software to ensure the accuracy of the geometry.
Air suspensions work best to maintain ride height as the total load changes like a full trunk and backseat. When used to allow an extremely low parked height the rule is to always return the vehicle to normal ride height for driving.  Driving your vehicle lowered or raised can cause damage to the vehicle and its components. Air ride does NOT allow you to vary the ride height for driving.
All Hub-to-Hub kits include the crossmember or frame stub kits from the previous page, manual rack & pinion, new spindles, springs, shocks, TUBULAR STEEL control arms, and upgraded OEM style iron disc brakes in 4 1⁄2” or 4 3⁄4” bolt pattern. We will not risk your safety with small 9” brakes!
For all Hub-to-Hub kits add $200.00 for power rack (we use the improved ‘79-’93 racks) and $80.00 to cover the rack main shaft extension used on widened kits. Narrowed ’35-’40 Ford kits use special rack & pinions add $250.00 For manual add $550.00 For power assist on the ‘33 -’34 For narrowed kits are manual only add $250.00. Ford narrowed kits must upgrade to Stage 3 coilovers.

MII Raised Spindles

Some hot rod enthusiasts prefer a more conservative ride height but efforts to raise the stance of a typical Mustang II IFS kit with taller springs and shocks can lead to other difficulties with alignment and geometry.
Fat Man continues to lead the way with an INNOVATIVE SPINDLE that raises the vehicle 1-1/2” without those problems. The spindles are fabricated duplicating the MII dimensions, however, some brake kits may require different calipers so the brake hose will clear your lower control arms. These will not work with factory stamped steel arms or some other manufacturers' tubular arms 
Precise CNC machining and TIG welding produce a very strong part and excellent fit.

OEM rims do not have the proper inside taper to clear a modern full-size caliper that didn’t exist when the vehicle was manufactured.

We strongly believe in sway bars to control body roll without an excessively stiff suspension.
Rear sway bars are recommended for many early vehicles, except pickups. Since most pre ’55 rods aren’t nose-heavy they rarely need front sway bars with independent suspension. Big block engines and power steering does increase the need for a front bar. We carry an assortment of sway bars for almost every application.
