Sierra Rear Differential

Locost Push Rod Rear Suspension

Anti Squat Independent Rear Suspension for a Locost / Haynes Roadster is not easy. I have used push rod rear suspension to get a rising spring rate and reduced hub weight

Caterham Rear Diff Cover

This Haynes Roadster incorporates a Caterham rear differential cover for increased clearance, along with roller bearing, urethane suspension joints.

Sierra Rear Shafts

There are many different Sierra rear drive shafts. Some are much longer than others but some that may be sold as one length may in fact be slightly different.

Rear Suspension

Fitting inboard shock absorbers and bell cranks to a Haynes Roadster has been a long process, mainly because Sierra Diffs now cost a fortune!

Granada Rear Hubs

Haynes Roadsters can use some pretty old parts, that will turn up in rather rusty condition. These Granada rear hubs were cleaned up using electrolysis and the results even surprised me!

Sierra Tripod Differential

Like many Locosts or Haynes Roadsters this build will use a Sierra Tripod Differential. Drawing it up in AutoCad has taken quite a few lunch hours!. I did notice that the Lobro and Tripod casing had very subtle changes

Sierra Cosworth Differential

Finding a Ford Escort Cosworth 4×4 LSD Diff for this Locost / Haynes Roadster build has taken ages. The prices are rocketing and the choices are getting limited. Luckily, I have mine.

Sierra 100mm Stub Axle

Granada Axle Flange

For this Haynes Roadster build I’ve drawn up Ford Granada 5 stud Axle Flanges in AutoCad. The dimensions will be used to decide upon brake options at a later date.
