Mopar arms will work fine with Rubi suspension.Installing Rubicon suspension on Sport. Mopar extended arms will cost $106 with shipping to Las Vegas or Rancho Sportarms are $200. Rancho arms say for lifts between 1.5" - 3.5".
Suggestions? Budget will not allow for more than $200
Thanks
Is that the quote from Allmoparparts, a vendor here?The arms are only like $31/ea but it’s $45 to ship to Las Vegas.
Those are the same length arms across all JL’s.could you use the rubicon control arms?
so why would a rubicon suspension on a non rubi need longer control arms?Those are the same length arms across all JL’s.
The higher you go, the lower the caster in degrees which makes the steering a little more sensitive/twitchy. The Rubi’s should come from the factory with Mopar LCA’s but they don’t. Probably comes down to cost reasons.so why would a rubicon suspension on a non rubi need longer control arms?
The underlying issue is that the OEM lower control arms are the exact same part for Sport/Sahara/Rubicon. [Hence using the Rubicon's LCA doesn't buy anything]. The Rubicon's should be longer to offset (caster-wise) because it's (slightly) lifted compared to the Sport/Sahara. This is considered to be something of a miscalculation by the factory's setup. So the go-to inexpensive solution is to use the LCAs from the Mopar lift kit because they are .25" longer than the stock bars. If you go to a higher lift, you'll need adjustable LCAs to get another 1/8" or so.could you use the rubicon control arms?
Great explanation brother, I appreciate itThe underlying issue is that the OEM lower control arms are the exact same part for Sport/Sahara/Rubicon.

Gotcha. Thank you muchThe higher you go, the lower the caster in degrees which makes the steering a little more sensitive/twitchy. The Rubi’s should come from the factory with Mopar LCA’s but they don’t. Probably comes down to cost reasons.
