indespension units

Mercury · 22 June 2016, 10:56

Hi My trailer indespension units could do with replacing, but not sure which to buy, Boat is SR4. with 50hp 2 stroke merc. Boat and trailer weigh approx 450 kgs. I don't think I need braked hubs. I have looked at some units but different weights are quoted eg. 250 kgs. 350kgs. and so on. Can any one advice me as to which to buy please. thank you...

331250840926 i just got these of ebay 500kg and galvanised

Linky for the above: TRAILER SUSPENSION UNITS 500KG WITH HUBS 4"PCD FULLY GALVANIZED | eBay

Usually sold as pairs & the weight given is the max loading for the pair.
If you intend to use your current wheels check that the replacements have the same PCD as the old: http://www.uk-trailer-parts.co.uk/wo...diameters-pcd/
Also check that the mounting holes in the new ones are the same number & spacing as the old or you'll have to deal with that.

Can I suggest before you buy that you take the trailer fully laden to a local weighbridge & weigh it just to be sure. Can sometimes be a bit of a surprise.
Also what does the plate on your trailer say weightwise?

If you are in Sheffield, as your details state, get yourself down 'Holme Lane' in Hillsborough, and have a word with one of the fitters at Towsure.

Been and done that, they want to sell me units with hubs and bearings already fitted, and charge me double. I just want to replace the units and use my own hubs and bearings, because they are in perfect condition having had a bearing saver fitted for the last umpteen years. I just needed to know which size units to buy. but I have just bought some from a co. called "Autow Wharehouse" I have gone for the 500 kgs. priced at just under £52. for the pair. Roof Boxes, Roof Racks, Trailers Parts, Snow Chains & Winches

Autow warehouse is the retail website for Peak Dynamics (who I buy my axles from). Good quality stuff.

Not like for like, no. You'll find that Indespension's boat trailer axles have mounting arms that hold the axle to the chassis rails, utilising three u-bolts on each side, which are specific to them.

Unless, of course, you just drill the chassis and mount the axle that way. In which case you can fit whatever axle you like. Just note that it'll then be fixed, with no adjustment, and you'll have four M12 holes through your chassis rails.

If you'd like I can see what they'll offer me an axle at trade for?

I guess not... I'm not on here all that often, so if you'd like some help best to email directly. All the best.

beerbelly · 27 June 2016, 13:55

Sorry I appreciate your offer I have been. Busy sorting a fuel tank full of crap out (I really wish folk were a little more honest when selling stuff) and at £320 plus vat for a new traile axler it will have to wait a while but thanks anyway for the offer of help

Although trailers these days have type approval from new, there are certain exemption for 'single use design' trailers ......... i.e. a boat trailer is for carrying boats and not a lot else, they are not a GP trailer.

On older trailers, homebuilt trailers, and rebuilt trailers, no plate is needed............ with an unbraked hitch the Plod / VOSA will take 750kg as the gross weight unless otherwise marked ...........

With a braked trailer, that is not weight plated, they will use the hitch plate info as the definitive gross trailer weight.
