Early TR4. This Fast Road full suspension package incorporates Superpro Polyurethane suspension bushes and is supplied for fitment to Early TR4's with TR3A type front suspension.

This package is suitable for road cars, which may take part in road rallies where a reasonable level of comfort is required.
As early TR4's don't have 3° of caster but later cars do, this kit includes all the necessary components to introduce 3° Caster.

The kit includes; 450lb/in front springs, 160 lb/in rear springs, a 1" front anti roll bar with conventional links and a 5/8" rear anti-roll bar with spherical bearing links. SuperPro polyurethane bushes are supplied for the front wishbone. The 160lb/in springs at the rear allow for a pleasant ride whilst the 5/8" rear antiroll bar provides the cornering ability. For a full list of contents and a fuller explanation of out kits take a look at our information sheet viewable at the 'Product Data Sheets' tab.

Revington TR's range of suspension packages should provide suitable suspension for any application. Below is a chart showing all the fast road/rally packages relevant to the TR4. This chart will help you choose which kit is best for you. Our range is split into early cars and later cars the difference being that early cars do NOT have 3° caster so for these cars we supply the appropriate top wishbone components to introduce this.

 

Customers should check carefully if they already have 3° caster upper wishbones. Take a look at the photo and note the shape of the arms and the style of the outer ball joint. If your top wishbone arrangement does NOT look like this, you do NOT have 3° caster front suspension and will need the suitable kit for the EARLY TR4. If your top wishbone arrangement DOES look like this, you DO have 3° caster front suspension and will need the suitable kit for the LATE TR4.

This Photo shows the upper wishbones fitted to our adjustable upper fulcrum which is also part of this kit.

TESTIMONIAL

Our suspension packages are renowned the world over for their engineering standards and performance. 

We recently had this email from Andreas in Germany who has just fitted our complete suspension package to his TR3A chassis : I am just finishing the Revington Suspension on the TR3 and I have to tell you it is a piece of art, I just cannot look somewhere else. Very nice! 

And from Paul in the USA: - Our race TR4 turned an all time fastest lap at Road America for that car, on the new suspension we got from you. It has been a race car since 62, so that is saying something for your products. We are very happy with the results. Thanks, Paul
