Rubicon Express Coil Springs

A: Do not powder coat springs, the heat from baking ruins the tempering of the spring.

A: We only have these available in the gray. If you want to powder coat them when you get them you can.

A: That answer isn't right. He's asking for overall length (which you should have on all your springs. They aren't 5.5" to 6.5" at ride height. They are 5.5" to 6.5" taller than stock springs.

A: Depending on the accessories you have installed, these coil springs are 5.5-6.5" tall.

A: Per Rubicon Express-Part Number 1345 &1352 are the same part for a 5.5" lift for the front spring XJ & TJ.

A: PN: RE1359 | Rear 7.5" | 224 lbs/in

A: Free Length 21.25 Spring Rate 164 lbs

A: Measurements are not taken at compression, only at free height. RE1373 are free length at 22.0-22.5”

A: RE1376 is correct. This part number is just a pair of coil springs.

A: Spring rate is 241lbs Uncompressed length: 19”

A: 2.5-3.5" depending on if you have heavy accessories mounted on the front (bumper, winch).

A: These are sold as a pair.

A: No, these should not sag with a V8. Adding heavier accessories like bumpers and winches would affect the spring height.

A: These coil springs are 5.5-6.5" lift height, depending on the weight of your accessories. If you have heavy bumpers or a hard top, this will affect your lift height.

A: Hi Anthony, The best people to ask would be in our customer service center. They know all the details about the Rubicon Express Rear Progressive Rate Coil Springs and what will fit on vehicles that have already been modified. They can be reached at 877-474-4821

A: Hi Austin, I recommend Rubicon Express 4.5 inch front lift coil springs. They are the best quality springs on the market. The part # R/ERE1310 at $174.99 for the pair. The complete Rubicon Express lift with front and rear springs is R/ERE6130 at $1049.99. I recommend the R/ERJX701B front shocks for 2 each and R/ERXJ507B rear shocks for 2 each. These shocks are made by Bilstein and are $79.99 each We can also offer you EXP55592 3 inch front coil springs for $160.99. I hope this is helpfull. Thank You Jon Snyder 4Wheelparts nt

A: Hello The Rubicon Express springs are not progressive. We do carry the Icon springs which are progressive for the Jeep JK's. Part number ICO 24010 and ICO 24015 Thanks

A: Thanks for the question Chris, You can measure the ride height at the shocks and then we can help determine your lift size.

A: These coils would require longer arms unless yours are adjustable, longer shocks and longer track bars. The sway bar links should be long enough.

A: Thanks for the question Bruce Rubicon Express Front Coil Springs R/ERE1370 These springs will work just fine for what you are doing to your vehicle. Thank you Answer box sales

A: Jeeper01ca, Thank you for asking. If you go to 5.5" coils such as the Rubicon Express Coil Springs Front TJ 5.5"/Pair you are going to need new brake lines,sway bar end links.The track bar might be off as well. You would probably be better off going to a 4.5" coil instead. http://jo.my/ad69hc

A: Eric- Thanks for the question. The amount of bump stop is a direct relation to your tire size. This means, if you lift 4 inches but run stock size tires you don't need any more bump stop. with a 4.5 inch lift on an Xj you can run 33 inch tires with minimal trimming. I would recommend 2 inch bump stop pucks by rubicon express found here http://jo.my/kclyqp . Remember, if you plan on going fast and hitting the bumps hard you should look at the stop material or the day star stinger system.

A: Chris- Thank you for your question. The spring rate for Rubicon Express Coil Springs Front TJ/XJ 7.5"/Pair is 213 lbs in. Over all un sprung length is 23.44 inches
