Thread: Trailing arm which one would be best?

I already use superpro

I had a quick look and came across two on a short search.

these ones from APT

APT Fabrication for Land Rover parts - Cranked rear trailing arms pair 2" lift

Of these ones from Terrafirma

Land Rover :: Accessories :: TERRA FIRMA Rear Castor Corrected Trailing arms (cranked suit lifted vehicles) PAIR Discovery 1, Range Rover Classic & Defender - Complete 4X4 - 4wd parts and accessories

now they are both the same price they both seem to have the same wall thickness but I think the apt ones are slightly larger in diameter only a little

however the APT are made from cold drawn welded tube and the Terras are made from co0ld drawn seamless should this come in to the decision making? or ultimately does it not matter?

Watching with interest as I just fitted TF radius arms to my 110 and am now considering APT or TF cranked arms to relieve the rear bushes.

Anyone know if either are longer than standard - my rear wheels are definitely attle further forward than they used to be....

Don't let welded vs seamless influence your decision making in the slightest.

I have noticed that too, some brands of aftermarket trailing arms seem short. When comparing a pair of 110s each with 3" lift on flat ground, one had Equipe arms the other Gwyn Lewis, the Equipe equipped 110 appeared to have a shorter wheelbase. Wouldn't have been by much but visually it was noticeable.

The Foundry 4x4 items when compared the std defender ones were exact same length.

careful fitting the wrong length trailing arms, the rear diff flange will no longer be in the same plane as the tc output flange, you could get out of phase vibrations & uj / spline wear

rather than using cranked arms you can get the same effect by using nolathane 48040 bushes, each half is angled about 15 deg and thus point your arms down toward the axle,( the center of its travel) . rather than horizontal, which is more like the upper limit of travel. that is probably why the std ones dont last. (apart from them being made by Britpart)

I haven seen a superpro so can't comment if they are the same

Before


After




they are going strong, after 4 months outback touring (towing van) they still look new

No the superpro are completely different and a MUCH better design IMHO. My SuperPro bushes have been in for >3 years now and are still like new.

The same SP bushes on mine (chassis end, upper trailing arm) have now gone well past 200,000km and are still fine.

The OE ones were flogged out by 80,000km encouraging lots of rear/roll steer, but standard rubber ones are superior, so the www experts would have us believe

I fitted SP's when I lived in NSW which was 6 years ago and they are as good today as the day I fitted them. Pat
