Hi working on a 74 Duster now.Thinking of getting the mopar xhd springs p4510269 left p4510268 right .Do these springs sit even ? OR should i get 2 right or 2 left.Thank you.

Contact spring n things

we dont have spring n things in canada buying from my local mopar dealer.

Worth ordering from them. Mopar springs are made in Mexico and have had many things wrong or go wrong on their springs. Just my .2

I hate to say it but 71rm23 is right. Forget about that Mexico made Mopar crap. Spend the extra money and go to Springs & Things. Down the road you'll be happy you did.

I'm proud to say it. ESPO has been a mopar staple on the northern east coast for 20 years+. Great prices and products.

XHD springs do generally sit even. It is the SS drag springs that tend to be uneven.

XHD has a nice moderately increased rate vs base model. As new and as designed they sit a little low. Also the newer MP versions seem to sag in use quite a bit which is why they get dissed.

I run a set of XHD's on an E body set up for handling. In that application low is good to a point but the spring rate was not enough and they sagged lower with time. A full leaf added at a local spring shop solved both problems for me.

I too have togive a shout out to ESPO as well. Friends have used them with great results as well

The Mopar Performance XHD springs do sit even when bought as a pair (correct L&R).

I put a set on my 67 Satellite 2 years ago.

I think that they might have settled a little as far as height, but if they did it wasn't very much.

The car rides at stock height, sits level and has a decent ride.

Are they the best springs? Who knows.

Contrary to what some think, not every car guys expectations are all the same.

Price will always decide which parts some people will buy.

Just a simple fact.

I'm guilty of it myself.

Would the ESPO (Springs and things) spring be better? Maybe.

Personally I don't think that M/Perf has the best track record on quality or warranty.
There is No warranty on M/Perf parts.

Why two part numbers if the springs are the same? There must be some difference between the two.

There is a difference between the left and the right spring.

There was on the factory Hemi/440 springs.
The XHD springs are built to their specs IIRC.

I bought my XHD/440-4SP/Hemi springs in 2006 from Summit. I bought 2 RH sides that came with 5 leafs and 2 half leafs. The car has not sagged since, in fact. I added a 1 inch lowering/spacer block to get the height where I like it.

The difference is the right has some extra leaves to resist driveshaft torque reaction on heavy acceleration. Seems like a nice feature and as posted, does not seem to result in noticeable ride height difference.
